I've Installed the newest version of Android studio, including the newest version of HAXM, ndk, sdk and whatever other related dependencies it installs. Intel Virtualization bios setting thingy I can't remember the name of is enabled and I have no trouble in virtual box and such.
I created an empty activity and tried testing it on the phone, works perfectly. Then I tried it on the emulator and there is a problem when it is hardware accelerated. It just opens a white window. The android studio displays 0 errors and thinks it ran the app properly. The graphics card I have is a gtx 1060 6gb. When it is software accelerated it works but is so slow I would rather use a chisel on a rock to draw the application usage.
So if someone knows a fix it would be nice.
Thanks
Well I have discovered that in order to solve the issue you have to go to the sidebar menu click More>Settings>OpenGL ES Renderer and(in my case) set it to Angle(D3D11) or Angle(D3D9) or Swiftshader. After that you simply restart the emulator and the issue should be gone.
For me Desktop native OpenGL and Autodetect based on host(which probably sets it to the first thing) don't work and leave you with a white screen.
In case someone finds this useful, you can set software acceleration as below and this solved the issue for me on Mac OS. (OP also mentions it works with software acceleration)
Tools > AVD Manager
Select virtual device
Click on Edit (pencil icon for me)
Click "Show Advanced Settings"
Look for Emulated Performance - Graphics
Select "Software" option
Current version of the emulator (27.1.3) doesn't work for me. The emulator just shows a white screen. Even playing with the gpu in the .ini configuration didn't work.
Once I downgraded to 26.1.4 (https://dl.google.com/android/repository/emulator-darwin-4266726.zip) the emulator started working again.
It seems that the Android Emulator is somehow conflicting with the NVidia Web driver on Mac OS. I had the latest NVidia Web driver (378.05.05.25f04) installed and I was having this same problem - the white screen whenever I used Desktop Native rendering (or left it at the automatic default which selects that as well).
I tried the Swift Shader as well, it works but the performance is abysmal!
On a hunch, I switched back to the OS X Default Graphic Driver from the Nvidia Pref Pane in Apple menu settings, and the Desktop Native driver is now working great after the computer restart!
The same problem can happen to the lightning fast Microsoft Android Emulators utilizing Hyper-V that work on both Intel and AMD CPU based PCs. The solution is in the same line as the accepted answer. For those who use Microsoft Android Emulators and land here by searching "android emulator white screen", here is the screenshot showing how to solve the problem by changing the default hw.gpu.mode from the default "auto" to "mesa":
So sorry
Check your onCreate method in your MainActivity.java, it should have setContextView(R.layout.activity_main)
I decided to try Android Studio 2.0 having used Eclipse in the past but I'm having considerable difficulty getting the AVD to load correctly. I've done quite a bit of googling and research into the problem, both here on SO and Google.So far nothing has worked.
The emulator simply hangs on the android load-up screen ever time I try to run it. I've seen it advised to use Genymotion but I would first prefer to resolve the issue natively in Android Studio to feel confident going forward using the IDE for building projects.
Here's what I've tried:
Complete reinstall of Android, SDK and SDK Tools
Install and configure of Intel x86 accelerator
Lowered the RAM amount to 512 in AVD settings
Multiple attempts at deleting and recreating AVD's
Tried creating different AVD phone models(Nexus One,Nexus 5x etc.)
Resetting ADB in AVD Monitor Tool
Starting ADB server from terminal
Restarting Android Studio multiple times after changes
Running SDK/SDK Tools updates several times
Made sure the SDK path is correct
These are the majority of the "solutions" I found either on other similar SO questions or by googling none of which has resolved the problem.
When I run the emulator currently it displays the following in the run window:
/Users/<username>/Library/Android/sdk/tools/emulator -netdelay none -netspeed full -avd Nexus_5X_API_23
Warning: requested ram_size 1024M too big, reduced to 512M
emulator: WARNING: Increasing RAM size to 1024MB
emulator: WARNING: VM heap size set below hardware specified minimum of 228MB
emulator: WARNING: Setting VM heap size to 256MB
Hax is enabled
Hax ram_size 0x20000000
HAX is working and emulator runs in fast virt mode.
console on port 5554, ADB on port 5555
The emulator shows up fine in the Android AVD Monitor devices pane and even appears to go through the entire booting process on the emulator screen itself but never gets to the Android home screen.
Also, Logcat seems to be looping continuously through dozens of errors and warnings, which don't offer any clear indication of what the issue might be or direction of how to resolve it.
I feel like I've exhausted every idea and not sure how to move forward.Just for the record, I am running El Capitan 10.9.2 with a 2.4gh Intel Core 2 Duo and 4gb ram.It's not the fastest machine for sure but should be capable of running Android Studio and the emulator.
Any help or guidance resolving this problem is gratefully appreciated!
For me this worked: in AVD(Tools->AVD) click on the small arrow for desired emulator then click on "Wipe data".
After that, it successfully started - passed the android logo screen - although a bit slowly.
You have two thing:
You should Increase your ADB emulator Heap to the minimum required.
in your case: 512M
into your AVD Manager:
Click Edit on your Emulator
"Show Advanced Settings" at the bottom
Go to: "Memory and Storage"
Edit the VM heap value to 512 MB
Finished
Image:
You can Wipe data to your Emulator. here is an exemple website
At one point my laptop hit a kernel panic and restarted while running an active AVD emulator session. When attempting to restart the emulator, the emulated device (Pixel 3) stayed stuck on the startup splash logo screen.
Fix steps:
Stop hung emulator session.
rm ~/.android/avd/name_of_emulated_device.avd/*.lock
rm ~/.android/avd/name_of_emulated_device.avd/*.qcow2
Restarting the emulated AVD should now be successful.
Windows equivalent for ~/.android should be C:\Users\.android, but I can't confirm this myself.
Note: You will likely lose any additionally installed apps and current work that was on the AVD.
Unfortunately, increasing the heap size didn't help in my case. The virtual device was actually running fine before with the previous amount of heap.
What I eventually ended up doing was just creating a new virtual device through the AVD manager leaving most of the fields the default value. The new device ran fine and booted up as expected and was able to run my app. It's possible something in my first virtual device became corrupted.
I had the same problem. I'm running El Capitan 10.11.5 with a 2.0GHz Intel Core 2 Duo and 8GB RAM, Android Studio 1.5.1.
After upgrading to Intel x86 Emulator Accelerator (HAXM Installer), rev 6.1.1 and deleting my API 14 SDK and related files, the newly installed API 23's Google APIs Intel x86 Atom System Image would not get past the Android logo screen.
After much trial & error, the Intel x86 Atom System Image (not Google APIs Intel x86 Atom System Image) for API 15 finally loaded the home screen on the emulator after ~ 8 min and one android system crash.
Will try the Intel x86 Atom System Image for API 23 later. Hope that helps.
I had the same problem and none of the steps listed here helped me, either.
But since the solution that worked for me was not mentioned here yet, I thought it might help you or one of the others finding this thread:
What did work for me was disabling certain settings in my Avast Antivirus as proposed by the Android studio troubleshooting page here.
My version of Avast did not have the setting "Use nested virtualization when available", however just turning off "Enable Hardware assisted virtualization" (note: restart is required for it to take effect) solved the problem just fine.
So if you are using Avast or another Antivirus which manipulates virtualization, be sure to look through the correspondent settings.
I had experienced same problem, What I did was, I clicked on the drop down in the actions column, then clicked on wipe Data, and that resolved it for me on ubuntu 20.04
I had this problem and running as admin fixed this (drove me crazy).
Hope this works for you too tried some many fixes.
What worked for me?
Create new project with same configs.
And start your old emulators in it.
What did not work?
Wiping data.
Increasing Heap size.
Creating new virtual device.
I also had the same problem with my AVD. After lots of trial and error I arrived at a solution for my problem. the problem was with the Heap size and the RAM size.
Initially the default heap size was 128 MB and RAM was 1563 , I just changed the heap size to 512 MB and reduced the RAM size( high RAM was making my pc run slow) also I enabled hardware acceleration. And Yipeee, it worked.
It's very easy to fix all you need to do is go in AVD Manager click on the small arrow on most right side of the screen beside the edit icon. Click that small arrow and select wipe data.
Now when you'll start your AVD it will restart and work properly.
I recently upgraded from Eclipse to Android Studio and I'm not really liking the experience. I'm comparing them both on a Windows 7 64 bit ultimate with 16GB of ram and Intel i7 4770 running NVidia Geforce 780 with the latest NVidia drivers if it matters and I'm running the latest JDK and the latest Android Studio.
The Android Studio is very slow in building the project which I can live with but it's also extremely resource intensive and sometimes slows down the PC to a crawl.
Whenever I'm building or running anything in AS, my PC seems to become extremely sluggish. It also causes flickering of screen and occasionally blanking my second monitor if I click on "Gradle build running" spinner which I find very odd. The RAM usage also shoots up to ~3GB which I find excessive for doing nothing (this is when it's idle after a few builds).
In addition, the panels at the bottom of AS keep jumping around which is a horrible user experience (moves from Android to Messages to Version Control or anything else on an ad-hoc basis depending on what's happening which is very, very annoying).
What I would like to know is basically:
1) How do I make Android Studio run better? I may be doing something wrong or missing some updates that I'm not aware of and I'm sure others have also noticed these behaviors and have found some solutions to it.
2) How do I "pin" the bottom panels so that they don't jump around and instead, let me, the user, navigate to them when I wish to instead of automatically switching them?
Many thanks and my apologies again if it's not the correct place for these questions.
Edit 1
Some more comments:
I'm using the latest stable build as of today. The build is Android Studio 1.2.2 Build # AI-141.1980579, Build on June 3, 2015
The behavior happens when using either Java 7 or 8. It doesn't appear to be related to the version of Java.
I am not using Presentation Mode. Just the vanilla view.
Doing the changes to the build configuration (thanks to #Blackbelt and his answer) appears to have helped with the build but the other problems with sluggishness and general user experience remain.
to sum it up
1) in AndroidStudio's settings > compile enable checkbox named Compile independent modules in parallel.
2) Under Help> Edit Custom VM Options I have:
-Xms1024m
-Xmx4096m # <------ increase this to most of your RAM
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=440m
-XX:+UseCompressedOops
-XX:-HeapDumpOnOutOfMemoryError
-Dfile.encoding=UTF-8
P.S. - Some people say Note, instead of VM options, it's better to combine can be overriden by combining those lines into one line single command in gradle.properties, like this :
org.gradle.jvmargs=-Xms1024m -Xmx4096m ......
3) I have an old dual core with 4GB ram, running ubuntu. Qs command line option I have only --offline (which specifies that the build should operate without accessing network resources). I also enabled the remaining checkboxes and now it's running ok:
Make project automatically
Use in-process building Configure on demand
Check the AndroidStudio's settings, under compile that the checkbox Compile independent modules in parallel is enabled.
Under Vmoptions I have
-Xmx2048m -XX:MaxPermSize=1024
I have an old dual core with 4GB ram, running ubuntu. Qs commandline option I have only --offline , which specifies that the build should operate without accessing network resources. I enabled also the remaining checkboxes:
Make project automatically
Use in-process building
Configure on demand
and it is running ok
Edit
It is possible to provide additional options through studio.vmoptions located at (just replace X.X with version):
Windows: go to %USERPROFILE%\.AndroidStudioX.X\studio.exe.vmoptions (or studio64.exe.vmoptions)
Mac: ~/Library/Preferences/.AndroidStudioX.X/studio.vmoptions
Linux: ~/.AndroidStudioX.X/studio.vmoptions (and/or studio64.vmoptions)
Increasing the value of -Xmx should help a lot. E.g
-Xms1024m
-Xmx4096m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=256m
-XX:+UseCompressedOops
will assign 4G as max heap, with initial value of 1G
Edit:
On windows the defaults are stored into C:\Program Files\Android\Android Studio\bin\*.vmoptions. The IDE allows you to tweak those values through Help->Edit Custom VM options (thanks to #Code-Read for pointing it out).
EDIT 2:
Android studio 3.5 makes easier to change same of those values. Just go to:
Preferences > Appearance & Behavior > System Settings > Memory Settings
Tips to make android studio fast:
Enable Offline Work:
Click File -> Settings. Search for "gradle" and click in Offline work box.
Go to Compiler (in same settings dialog just below Gradle) and add --offline to Command-line Options text box.
Improve Gradle Performance
gradle can be optimized too. The easy way is to modify the settings in global gradle.properties (create it if not exists in the following folders: Windows - C:\users\your_name\.gradle\; Linux- /home/<username>/.gradle/; Mac- /Users/<username>/.gradle/; ) and in that file, add these two lines:
org.gradle.daemon=true
org.gradle.parallel=true
For More: http://www.viralandroid.com/2015/08/how-to-make-android-studio-fast.html
I detected another reason - Thumbs.db, which affected performance badly.
Go to File > Settings > Editor > File Types and in field Ignore files and folders add this: Thumbs.db;
Now, Android Studio runs like a charm.
Adding more memory helped me:
Click "Help"
Edit Custom VM Options
Android Studio 2.1.2 Edit Custom VM Options:
Change values
like below:
-Xms512m
-Xmx2560m
-XX:MaxPermSize=700m
-XX:ReservedCodeCacheSize=480m
-XX:+UseCompressedOops
Restart Android Studio
Recommendations:
MUST TO SAY: if you have any chance, spend some money for better PC(cpu),
it's Most important ..
Tweaks:
Some people say, that OS (Operating System) might cause much slowness. For example, XP or LINUX (or etc) was mentioned to perform 70% faster (don't know why..).
Disable VCS by File > Settings > Plugins and disable the following things :
CVS Integration; Git Integration; GitHub; Google Cloud ... things; Subversion Integration; hg4idea;
Editor is a resource eating too (especially on Large Monitors) and slow. Make it much much faster: click Help > Edit custom VM options and add these lines :
-Dsun.java2d.d3d=false
-Dsun.java2d.opengl=true
save it and Restart Android Studio.
If Android Studio has a proxy server setting and can't reach the server then it takes a long time to build and waiting for a timeout. Removing it helps much. File > Settings > Appearance & Behavior > System settings > HTTP Proxy.
Another Useful quote (from article):
Modules are expensive… On my current project I had to build some libraries from scratch and had to fork some that almost fitted my needs but not quite! If that modules are not constantly modified, it’s important to have this into consideration: the time needed to compile them from scratch, or even to check if the previous individual module build is up-to-date, can be up to almost 4x greater than to simply load that dependency as a binary .jar/.aar.
Hint: run the gradle build -profile for an HTML report showing where
the time goes regarding the build process.
Note: keep that “unnecessary” modules in your version control system
for the eventuallity of a quickfix/improvement in that dependency.
In your Gradle build script, use only
specific Google Service, like: compile 'com.google.android.gms:play-services-maps:...'
Instead of full Google Library: compile 'com.google.android.gms:play-services:...'
(Compile time goes from 2 minutes to around 25 seconds).
Gradle configures every project before executing tasks, regardless of whether the project is actually needed for the particular build. In global gradle.properties adding this will help much: org.gradle.configureondemand=true
Surprisingly, some people say , they solved problem by reducing: 1) heapsizes to -Xmx256m (instead of higher values); 2) Emulator Ram-size (from Edit AVD > Advanced Settings);
Everyday Recommendations:
Don't run multiple projects simultaneously.
Don't close emulator after using once (use same emulator for running app each time; If you test large apps, better to use a real mobile phone instead of emulator).
clean your project every time after running your app in emulator - click Build > Clean Project (or Rebuild), you can use keyboard shortcut.
An anti-virus is causing the slow-down
In one particular system I looked at, this issue was caused by an over-zealous anti-virus that was interfering with Gradle, the build manager for Android Studio. It seems every time Gradle was "touching" a .jar file, the virus checker was unzipping the .jar and scanning it for viruses first. The Gradle build could only continue once the unzipping and scan was complete, thus leading to very long build times (5 min plus). Since Android Studio, by default, runs a Gradle build when you start up, it manifests as an extremely slow start-up.
The problem is extremely easy to check for:
While you are experiencing the symptoms of a slow Android Studio, press Ctrl- Alt-Delete and open Windows Task Manager.
Click on the Processes tab to see the active processes and sort by CPU. If you see an anti-virus taking significant amounts of CPU percentage intermittently while Android Studio appears to be loading, it is likely to be the same issue.
You can verify further by looking at the scan logs of the anti-virus to see if it is indeed, examining the .jar files.
To solve this, you will have to add the correct directories to the "excluded folders" of your anti-virus. Assume that your Windows username is "Username" and you have installed Android Studio on C: drive. You would then request to exclude from the virus check the following directories:
C:\Users\Username\.android
C:\Users\Username\.AndroidStudio2.2
C:\Users\Username\.gradle
C:\Users\Username\.m2
C:\Users\Username\AppData\Local\Android\Sdk
Please note that you may need to take additional security precautions if you exclude these directories and you should co-operate with your security department in the workplace. This may involve setting up your own Maven repository if deemed necessary.
(I am aware that this is a late answer, but none of the previous answers have addressed this potential issue)
The best way to boost up android studio runtime performance is to use SSD Drive. It will boost the performance as very much. I did all the above things and felt I should go for new laptop, but suddenly I came to know about SSD Drive and I tried it. Its Much Much better.....
Starting from Android Studio 3.5 some of the settings can be configured via:
Preferences > Appearance & Behavior > System Settings > Memory Settings
As you are learning, performance problems with AS are not trivial to diagnose! In my case, an array of 9215-character-long strings (see below) was causing AS to dump threads every time I typed a few characters. The thread dump in turn caused AS to freeze for many seconds at a time. This bug appeared in the Windows 64 bit release of AS 2.2, still occurs in 2.2.1, but was not present in 2.1.
Finding out that long strings were causing my lockups involved a lot of trial and error. But, I learned a lot in the process, to wit:
idea.log contains excellent diagnostics (Help->Show Log in Explorer);
If you see extreme, but intermittent slowdowns, suspect AS is dumping threads. This will be reported in idea.log. If threads are being dumped, the dumps will tell what code AS was executing when the problem occurred;
Find out whether the problem occurs in other projects. If not:
Look for unusual content in the project file you are editing when it happens (atypical indentation, long lines, overall size, special characters, etc.);
Try exporting settings from another project (File->Export Settings) and importing them to the problem project (File->Import Settings);
If so:
If threads were dumped, consult these and text in idea.log near in time to the dump notices for details;
Consult idea.log for messages about memory consumption and see other answers to this question such as https://stackoverflow.com/a/30818099/5025060 for advice regarding memory and other tunables.
BTW, for the present I have worked around the problem I describe above by moving my long strings into a separate file (a new class containing only the array itself). I try not to edit this file with AS:
package com.code_read.numerous;
// Stored in this separate file as workaround for but in Android Studio 2.2 and 2.2.1:
public class numstrings {

It's not compiling that's hurting me here, it's the typing. I could disable all the smart features and be back to notepad++ like TomTsagk suggested in a comment. For today I need more cores and RAM.
Playing devil's advocate I'd argue that typing shouldn't require a 16Gb PC octacore PC. Liked Sajan Rana's advice but things are so slow here it felt mostly a placebo.
To be fair I am using 1.4RC1, which is just short of being in the stable branch. Turning the internet off helped a little. The new feature of simultaneous Design (Preview) and Text views working with XML layouts is very helpful.
No, it is ridiculous. Never leave the stable channel.
This answer pertains to slow Gradle build speeds for Windows 10 after you've already gotten the Xmx and Xms memory settings straightened out.
Windows Defender
As far as Windows Defender is concerned it's simply not enough to add folders / files to the Windows Defender exclusion list via "Files" or "Folders".
You must add directories pertaining to Android Studio / Gradle / Java (embedded JDK or Oracle JDK) as "Process" exclusions to Windows Defender :
Go through the answer by David Rawson
During a Gradle build... monitor the Windows Task Manager's Processes
To Windows Defender, add "Process" exclusions for directories containing the file/executable you see utilizing the CPU during a build associated with Android Studio / Gradle
This obviously comes with security implications.
The following describes more details pertaining to using a "Process" exclusion in Windows Defender (as opposed to adding a simple "File" or "Folder" exclusion) :
A file name with full path causes the particular binary file to be excluded, i.e. any files it touches, regardless of where the file is located, will not be scanned by Windows Defender. A file name without any path causes any binary file with this file name to be excluded regardless of its location. A path followed by a "*" (e.g. c:\my\private\tools*) causes any binaries under this path to be excluded. Any files touched by these processes will be excluded. This is different from a path exclusion, where files touched by any process under the excluded path is excluded.
The key here being....adding these exclusions as "Process" type exclusions takes into account "files the binary touches" as opposed to manually finding and excluding every file / folder that is generated by Android Studio / Gradle.
Windows File Indexing
Windows file indexing seems to also slow down Gradle builds. Turn off Windows File Indexing for the directories used by Gradle / Android Studio.
Here are my "Windows File Indexing" and "Windows Defender Process" exclusions :
C:\Program Files\Android\*
C:\Users\<yourUserAcct>\.android\*
C:\Users\<yourUserAcct>\.AndroidStudio3.0\*
C:\Users\<yourUserAcct>\.gradle\*
C:<pathToYourAndroidStudioProjectFolder>
In case setting -Xmx4096m -XX:MaxHeapSize=256m (and etc.. mentioned in above answers) doest work, then do this manually:
Step 1 : Start Android studio and close any open project (File > Close Project).
Step 2 : On Welcome window, Go to Configure > Settings.
Step 3 : Go to Build, Execution, Deployment > Compiler
Step 4 : Change Build process heap size (Mbytes) to 1024 and Additional build process to VM Options to -Xmx512m.
Step 5 : Close or Restart Android Studio.
This might sound stupid and off topic but in my case I was using an external 4k Monitor with my MacBook Pro 13' (MacOS High Sierra, 2016) and I had the resolution set to the wrong scaled resolution. Switching to another scaled resolution where there was no "using a scaled resolution may affect performance" warning resolved my overall performance issues. In my case I had to increase the resolution to max.
So for me it was an overall performance problem which first surfaced with Android Studio, it was not an Android Studio specific problem.
EDIT 25.11.2017
As a result I had to increase font sizes in Android Studio:
and on my Mac in General. I followed some of these tips to get that done.
Just for anyone looking, after upgrading to El Capitan, I noticed a huge lag with the IDE. After increasing a ton of RAM and using the suggestions above, it turned out that I needed to update the legacy Java, and reinstall via: https://support.apple.com/kb/DL1572?locale=en_US
After installing this, all lag was gone.
Well, one thing that worked for me is using physical android device instead of emulator. As in my PC( i5 and 4GB RAM ) the android studio takes about 700MB of memory and the emulator takes another 700. Thus the whole performance of the computer goes down. Working with a physical device saves the strain from the emulator.
DO NOT EDIT studio.vmoptions ,It may not work.
In gradle.properties file (in app directory) add this :
org.gradle.parallel=true
org.gradle.jvmargs=-Xmx7g -XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
I followed this post and it worked great for me.
EDIT:
Following tips have been mentioned in the above post.
In gradle.properties, put this:
org.gradle.daemon=true
org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
org.gradle.parallel=true
org.gradle.configureondemand=true
And in build.gradle, put this (Note this will disable lint check):
tasks.whenTaskAdded { task ->
if (task.name.equals("lint")) {
task.enabled = false
}
}
I just want to share my case:
if you need play-store library, don't compile all of it, just compile library that you need. example: if you only need maps library instead of compile 'com.google.android.gms:play-services:9.0.2' do this compile 'com.google.android.gms:play-services-maps:9.0.2' on your gradle
Dont use OpenJDK for the java, I use java 7 oracle and it works well. if yout need to change default java do this on linux terminal sudo update-alternatives --config java and pick the number
I'm using ubuntu 32bit 4GB RAM. that's all the issue I ever encounter with AS.
There are many ways to speed up Android Studio.
Speed up gradle build time.
1.Go to Project gradle.properties file and remove comment from both line.
2.copy gradle.properties file to your .gradle folder so that you don't need to setup for every project.
Enable Work Offline so that Android studio/Gradle don't need to check for newer file over internet every time.
I've quickly resolved this issue by upgrading gradle (Android Studio seems to use old version).
1) Download latest version (https://gradle.org/gradle-download/) and unpack somewhere.
2) Update path in Android Studio: File > Settings > Build, Ex../Gradle
This worked for me!
Open build.gradle (it's inside your project) and change the both jcenter to mavenCentral
(you can do it in Global file too: C:\Program Files\AndroidStudio\plugins\android\lib\templates\gradle-projects\NewAndroidProject\root\build.gradle.ftl however, you will need to do this modification again after AndroidStudio upgrade)
My Android Studio was not only slow in general use, but also when building.
Here's what I did:
Uninstalled Android Studio (Don't delete, uninstall it and check delete the SDK too). Then delete Android folders located in C:\Users\\ folder namely: .android, AndroidStudioX.X
Uninstall the SDKs via the SDK manager, remove everything ( If there is lef SDK folder, delete them )
Download and Reinstall the latest build for Android Studio (v2.1.2 as of this writing); Install only the SDK/Emulators you need;
It's fast now.
My Story before that:
My laptop sports an Intel Core i7-3612QM and 8gig of ram. When I builded, all the 4 cores/8 threads were on 100% usage. My entire system froze until the ~10 minute wass done. Gradle took me like ~10 unproductive minutes of slow down. This is very annoying. I am using Android Studio since 1.4. There were also tremendous slow down when I copy paste code to and from, selecting menus, right-click context menus, editing manifest, editing gradle files, opening layout files, rendering in the UI Editor, etc. Its was very unusable most of the time.
Due to frustration, I did the above steps. Its fast now. Very usable just as before. I build for only ~20 seconds compare to ~10minutes before that. Also, Android Studio eats about 6gig with emulator and browser with lots of tab open, unlike before its hovering on 98% RAM usage. Not just that, I even saved 45 gigs of space for whatever reason. I only use couple of SDKs and Emulators when I checked the Android SDK folder, it occupies 45gig of space! I think the IDE is having a hard time accessing/IO on my SDK folder.
If you've tried other given solutions and still experiencing the same issue, it may be time to remove Android IDE/SDKs altogether and start anew (it might take you sometime to setup that newly, but its worth it. Considering I've been suffering this sluggishness for months and cost me my productivity).
I really guess that this might be caused by cumulative patches that has been done since then. Or the 45 gig SDK folder on my poorly defragmented drive. I don't know and I could be wrong.
Thank you! HTH
I should mention that if you are using Mac, downloading and running an app from the App Store (like "iBoostUp" etc.) which will clean out unused system files can speed up your computer dramatically, including AS.
I also found that adding more memory to my Mac sped up AS as well.
I noticed that AS transfers too much data from/to HDD. It is very annoying, especially when starting to write a new line of code. So, I think, better will be reinstalling a hard disk with SSD. I have i5 with 6 Gb of memory, and the CPU seldom loads more than 50% even at build time. So, the most weak place is HDD.
Click Help > Edit Custom properties and add this line:
sun.java2d.noddraw=false
... worked successfully for me to fix the speed issues (Windows 10 64-bit). It's absolute voodoo as far as I'm concerned (I haven't done any research on why that should work), and there is a warning above that property that it can cause blinking and fail to repaint on some graphics cards, but there you go. (Inspired by LairdPleng's comment, further information)
1 The most common cause of slowness is using Emulator, especially more than one. USB debugging with the external mobile device can be used.
2 Invalidate caches every month or so
One Simple thing that no one has mentioned is File>Invalidate Caches.
Please add in setting.gradle (root folder)
startParameter.offline=true
I have tried to measure speed of Android Studio 3.1.4 on the same hardware: Macbook Pro 2011, RAM 4Gb, SSD 240GB Samsung, Core i5 2.4Ghz. I have installed on this machine 3 different OS: Windows 10, MacOS Hight Sierra 10.13, Ubuntu 18.04. Avarage build time (running command: gradlew clean build, gradlew clean assembleRelease) on MacOS/Ubuntu was around 30% faster than on Windows.
On my another working machine: Core i5 3.0 Ghz 7400, RAM 16Gb, SSD 250Gb. Build time takes 4.34min on Windows 10 machine. The same project on a little bit slower processor, but with the same RAM and SSD and it is running Ubuntu 16.04 build time takes two times faster!! Well I was shocked with results, but still I choose Windows as development machine, because it's much more comfortable for me to use comfortable and usable keyboard and sotfware than on Unix like systems. And even if I had to choose between MacOS and Ubuntu - mac is really much easier to setup everything, and Ubuntu is too complex to use for usual people. Choise is up to you.
Apart from following the optimizations mentioned in existing answers (not much helpful, was still painfully slow), doing below did the trick for me.
HP Notebook with 6 GM RAM and i5 processor I have, still android studio was terribly slow.
After checking task manager for memory usage, noticed that there is a software called "HP Touchpoint Analytics Client" that was taking more than 1 GB memory.
Found that it's a spyware installed by HP in Windows 10 after searching about it in Google.
Uninstalled a bunch of HP software which does nothing and slows down the system.
Now, Android studio is considerably fast - Gradle build completes in less than 30 seconds when compared to more than 2 minutes before. Every keystroke would take 5 seconds to respond, now it is real time and performance is comparable with Eclipse.
This might be true for Laptops from other vendors as well like Dell, etc.
HP really messed up the user experience with their spyware for Windows 10 users.
Uninstall them, it will help Android studio and improves the overall laptop experience as well.
Hope this helps someone. Thanks.
