I have changed studio64x.vmoptions file to make studio faster but ever since I made change, android studio is not opening. it shows error about JAVA_HOME environment variable but I already have added that. please help!
tried reinstalling android studio, adding Java_Home , deleting studio64x.exe.vmoptions. still not opening
I was able to resolve the same issue (Android Studio was not opening) by refer to the solution provided in Android Developer Portal,
Studio doesn't start after upgrade
If Studio doesn't start after an upgrade, the problem may be due to an invalid Android Studio configuration imported from a previous version of Android Studio or an incompatible plugin. As a workaround, try deleting (or renaming, for backup purposes) the directory below, depending on the Android Studio version and operating system, and start Android Studio again. This will reset Android Studio to its default state, with all third-party plugins removed.
For Android Studio 4.1 and later:
Windows: %APPDATA%\Google\AndroidStudio Example: C:\Users\your_user_name\AppData\Roaming\Google\AndroidStudio4.1
macOS: ~/Library/Application Support/Google/AndroidStudio Example: ~/Library/Application Support/Google/AndroidStudio4.1
Linux: ~/.config/Google/AndroidStudio and ~/.local/share/Google/AndroidStudio Example: ~/.config/Google/AndroidStudio4.1 and ~/.local/share/Google/AndroidStudio4.1
unable to connect to adb.check the event log for a possible issue, verify that localhost entry is pointing to 127.0.0.1 or:: 1 for ipv4 or ipv6
Tried adb kill-server, restart, invalidate restart nothing works.
Same issue reported over here https://issuetracker.google.com/issues/130791561
Note: I have not added any file or anything in studio, it's fresh installed Studio after format a full system still issue is there.
Replace your platform-tools with this one and delete the other one.
https://dl.google.com/android/repository/platform-tools_r26.0.0-windows.zip
I was also facing this issue in android Studio 3.4 version, but now I have fixed it , if you are using windows then follow these steps:
Download Platform tools from here
https://dl.google.com/android/repository/platform-tools_r26.0.0-windows.zip
Extract downloaded zip file
Go To location "C:\Users\your_computer_user_name\AppData\Local\Android\Sdk" and Delete "Platform tools" folder
Copy and Paste, downloaded platform tool folder to above location
Now Go to your android studio and Rebuild your project Then run.
For Mac Users, follow these simple steps :
Just simply Navigate to Tools > SDK Manager> Android SDK>, then click on the Tab of SDK Tools, then look for Android SDK Platform-tools and update it.
Then the last step, Invalidate cache and restart your IDE, after that, then finally you restart your Mac. (Sometimes it's this step is unnecessary)
It will work out successfully.
Solution for Linux Users.
System info: Linux Mint Cinnamon 19.1 , Android Studio 3.4.1
Issue description: Problem with platform tools.
Solution: Remove the folder manually and update SDK tools through Android Studio.
Step 1: Go to your Android SDK installation folder. By default under your home directory. Choose platform-tools and simply delete. (/home//Android/SDK)
Step 2: Open Android Studio and go to SDK Tools. (File -> Settings -> Appearance & Behaviour -> System Settings -> Android SDK -> SDK Tools) By the moment you should be able to see Android SDK Platform Tools line unchecked.
Step 3: Put a check to install Platform Tools and press OK. Notice it'll relocate the folder to the directory where deleted.
Now that you re-installed the platform tools, restart the Android Studio and your deployment targets should show up.
If you don't install the platform tool back and ever try to build or run a project you'll get this IDE error. Just FYI :)
So that's all. Enjoy.
Happy coding
If you use Windows, you might have a corruption in api-ms-win-crt-runtime-l1-1-0.dll.
Try to update it - you can get the update from Microsoft's website.
You should check it - path/to/sdk/platform-tools and try to run adb.exe
When you update Sdk platform tools(which contains adb.exe) to release 28.0.2 and if you are using windows 8.1 then it needs few updates from windows.
As per SDK Platform tools release notes(https://developer.android.com/studio/releases/platform-tools):
Updated Windows requirements : The platform tools now depend on the Windows Universal C Runtime, which is usually installed by default via Windows Update. If you see errors mentioning missing DLLs, you may need to manually fetch and install the runtime package."
Windows update url: https://support.microsoft.com/en-ca/help/2999226/update-for-universal-c-runtime-in-windows
Prerequisite for Windows update url: https://www.microsoft.com/en-us/download/details.aspx?id=42327
Faced the exact same issue but after updating with prerequisite url first then the other url provided now it is working perfectly fine for me.
It worked for me by selecting -> Use libusb backend
This worked for me on Windows:
Goto cmd write %temp% hit enter -> delete all data from there.
Restart your Computer.
Open Android Studio now, it will work.
Clear all cache memory (related to Android Studio)
Restart ADB manually from Android Studio (first option)
Open Command prompt and got android sdk>platform-tools> adb kill-server
press enter
and again adb start-server
press enter
Restart ADB manually form Android Stidio (second option)
go to your (SDK store path) sdk>platform-tools>adb
press enter
ex. D drive > sdk>platform-tools>adb
Restart your system
Delete the platform-tools folder from the sdk and replacing with the same from your another pc. I am also facing this problem after updating to 3.4. If you face same problem please update to Android Studio 3.5 Canary Channel.
The reason is for ADB server problem. Simply re-run your adb.
(Go to your SDK folder then inside platform-tools folder you can see adb.exe. copy the path location and paste it in your computers system Environment variable. Set a new path there and paste the adb.exe file location there. hope it will solve )
If you are using Genymotion, there is an update that fix the problem.
Genymotion 3.0.2 (April 18th, 2019)
Corrections
We have fixed an
incompatibility with the adb tool bundled in the platform-tools 28.0.2
package of the Android SDK, which caused failures to start virtual
devices.
This new version of adb changed the behavior of the “adb connect
:” command by making the “port” part mandatory. This
broke Genymotion Desktop in a few places where it did not pass the
port. We have adjusted the way we call “adb connect” and also updated
the version we ship with the product to match the one in
platform-tools 28.0.2.
If non of the above answers worked for you (as same happend to me), down grade to the old version of Android Studio by following these steps:
Uninstall current Android Studio
Go to Android Studio Archive and download any older version
After installation, Open the project. You might see an error like this
This version of Android Studio cannot open this project, please retry with Android Studio 3.4 or newer.
Now, open project gradle and update classpath tools.build version. I.e. in my case Android studio version is 3.2 and classpath 3.2.1
Hope it might save someone time.
I faced this issue last night, and I tried these methods to fix:
download older platform-tools and place it in the android sdk folder.(not work for me)
adb kill-server, adb start-server.(not work for me, adb had no response with these cmd)
kill the process that occupies port 5037.(for me, there is no other .exe run at this port)
reinstall platform-tools in Android Studio.(not work)
download ADB Kits and replace them in platform-tools folder.(work!!!)
It seems that my adb file has been modified or replaced by some programs. You can try these methods, and I hope some of them can work for you.
I had this issue only after a Genymotion update, on Mac.
What worked for me: Open Genymotion preferences, Select ADB, choose "Use custom Android SDK tools" and points to your Android SDK folder.
Actually the problem is not with the android studio version 3.4
Problem is with the android platform tools version which is latest one 29.
So install the previous version of the android platform tools version it will solve your problem. as above #Ved mentioned.

EndTask adb.exe from Background processes (TaskManager) and Run Application again.
It works for me
I'm completely new to Android and Android Studio. I was just coding.
So I was running the previous version of Android Emulator and it worked perfectly fine.
However, when I downloaded the latest Android Emulator 27.1.12, my Emulator couldn't run properly.
Issue: The code is running fine, but the Emulator can't display my application. When I click on the Emulator screen, I can still hear the Audio of my app. So I think the problem would be with my computer's hardware.
Because the Emulator couldn't run, I uninstalled the Android Emulator 27.1.12 and Android Studio reported these errors:
Issue:
08:32 Emulator: [6684]:ERROR:android/android-emu/android/qt/qt_setup.cpp:28:Qt library not found at C:\Users\dell\AppData\Local\Android\Sdk\emulator\lib64\qt\lib
08:32 Emulator: Could not launch ‘C:\Users\dell\AppData\Local\Android\Sdk\emulator/qemu/windows-x86_64/qemu-system-i386.exe’: No such file or directory.
So, when I install the Emulator, it crashes, when I un-install it, I encounter these 2 errors. So is there a way for me to use the Emulator without causing the 2 errors?
I am not sure from your question, whether or not you have uninstalled and reinstalled the AVD Manager, so in the case you haven't:
I suggest you completely uninstall and then reinstall the Android Virtual Devices SDK (AVD Manager).
You can use the following instructions to help you out:
To uninstall/install the AVD Manager, go to Tools > SDK Manager > Android SDK and select the SDK Tools Tab. Then scroll down until you find the Android AVD/Virtual Devices SDK.
Also, make sure that the Android Emulator SDK is also installed.
I see in the new update of Android Studio, the Android Emulator option is not enabled by default.
So, let enable it in the Settings as the bellow and run Android Emulator again.
Have Android 3.2.1 which you need to install emulator manually by going into
Tools > SDK Manager > Android SDK and then select the SDK Tools Tab. Check the 'Android Emulator' then Apply.
Few days ago I have received an update patch(I don't remember what for were that update it was 5 MB of size), after installing it, studio somehow crashed and stopped working, when I'm starting it there is not wizard for creating android project. I tried to uninstall every file of android studio then download fresh download pack, install it but same problem. (OS Ubuntu 16.04)
Possible reason Plugin for Android is disabled or removed/corrupt
From your Home Screen of your Android Studio
Configure -> Plugins -> Enable Plugin for Android
Then Ok, and Restart
In my case, it was the Android Studio file corrupted file problem.
Close your Android Studio then Delete .AndroidStudio directory from the Users directory and start Android Studio Again is works for me.
C:\Users\[use_name]\\.AndroidStudio
My android studio 15.1 gives this error when i try to run an emulator and it does not allow me to click on the button AVD manager. please help
I was faceting the same error. When I had been trying to add a new Virtual Device Android Studio was telling me Android Emulator was not installed even though it was installed. If I was keeping trying to add to the virtual device it warned me to check logs.
Looking at my idea.log file I found the following message
'mksdcard' is missing from the SDK tools folder.
So I tried to reinstall Android Emulator from SDK Manager at Tools -> SDK Manager and it was solved.
