I just moved to Android Studio from Eclipse, and I found that it always shows "fetching documentation" when I use quick documentation (Ctrl+Q).
How can I solve this problem?
I downloaded the documentation for API 19, and the problem persists.
The problem is Android Studio does not automatically update the source link of reference even when the documentation is already downloaded.
The default link in jdk.table.xml is http://developer.android.com/reference/ (android studio tries to connect to this online server even if the network is blocked).
To solve the problem, we can just redirect the reference to local source.
MacOS
On MacOS, the config file jdk.table.xml is under
~/Library/Preferences/AndroidStudio<version>/options/, and the docs are here:
~/Library/Android/sdk/docs/, or the custom path of your Android SDK.
In jdk.table.xml, find all the lines:
<root type="simple" url="http://developer.android.com/reference/">
and modify them to
<root type="simple" url="file://$USER_HOME$/Library/Android/sdk/docs/reference/">
Windows
On Windows, the file jdk.table.xml is under
C:\Users\Name\.AndroidStudio<version>\config\options
In AndroidStudio 3.3, modify to
<root type="simple" url="file://$USER_HOME$/AppData/Local/Android/sdk/docs/reference" />
Android Studio (any os)
Then, in File -> Invalidate Caches / Restart… select Invalidate, and retry using Quick Documentation. It should display instantly. If it doesn't, select Invalidate and Restart, and you should be good to go.
Update:
On the newest Android Studio versions you can do as following:
Navigate to Tools > SDK Manager
Select the SDK Platforms tab
Make sure the Show Package Details checkbox, at the bottom right, is checked.
Select your target API level from the list, check the Sources for Android [API_Level] and click apply.
For older Android Studio versions:
Go to: Tools > Android > SDK Manager. Select SDK Tools tab and:
if Documentation for Android SDK is unchecked, check it and click apply
If Documentation for Android SDK is checked, uncheck it and click apply. After uninstall completes check it again and click apply.
UPDATE: out-of-date, please check #Htea's answer.
I was having the same issue as you. Here's what fixed it for me:
Make sure you have the Documentation package downloaded in SDK Manager.
Exit Studio if it's running.
Delete the file named "jdk.table.xml" located in ~/.AndroidStudioX.Y/config/options/ (remember to take a backup first!).
Relaunch Android Studio. should work correctly now and it should regenerate the file automatically.
Note:
This worked for me on Ubuntu 14.04 & Android Studio 0.8.11 (EDIT: Several users are reporting this solution also works for newer versions of Android Studio).
If it still doesn't work, try deleting and re-downloading the Documentation package from inside Android SDK Manager then try the above steps.
If you're running Windows, the file is located at "%UserProfile%.AndroidStudio\config\options", and if you're running OS X, it's located at "~/Library/Preferences/AndroidStudio/options" (credits to #Gero and #Alex Lipov).
Hope it helps.
The reason for me was that I had not downloaded sources for my SDK version defined by compileSdkVersion property in the build file (now called compileSdk in AGP 7.0.0).
So, in Android Studio 4.0 and higher do this:
Go to Settings 🡲 Android SDK 🡲 SDK Platforms tab 🡲 select Show Package Details checkbox at the bottom 🡲 under your target API Android section check the Sources for Android xx 🡲 click Ok and wait for the download to finish.
Thanks to Cyn45 for their answer.
As other answers said, it's because the Android Studio is trying to fetch the javadoc online (from http://developer.android.com/reference/), which will be very slow if the network not good, especially in China because google is blocked. So we should change this setting and let Android Studio fetch javadoc locally:
Download Android SDK Documentation using the Android SDK Manager.
Open the file ~/Library/Preferences/AndroidStudio2.2/options/jdk.table.xml, see notes below to make sure the correct file is edited.
In the file jdk.table.xml, replace all http://developer.android.com/reference/ to the path to your sdk reference folder. For example file://$USER_HOME$/tools/adt-bundle-mac/sdk/docs/reference on my Mac.
On OS X, if you have used several versions of Android Studio, there may be several configuration folders for each version (under ~/Library/Preferences/), you should change the jdk.table.xml in the right folder, in my case I should edit jdk.table.xml under the folder AndroidStudio2.2.
On Windows
File location of jdk.table.xml
C:\Users\[your windows user name]\.AndroidStudio2.3\config\options\jdk.table.xml
Notes
"." before AndroidStudio directory
version number after ".AndroidStudio". Be sure to edit the version number of Android Studio you're currently using. Previous versions will still have directories here as well.
Line to edit
Before
<root type="simple" url="http://developer.android.com/reference/" />
After
<root type="simple" url="file://C:/Android/sdk/docs/reference" />
Notes
C:/Android/sdk/docs/reference replace with Android SDK location on your machine
if you're copy/pasting location from File Explorer, replace backslashes (\) with forward slashes (/)
Each installed Android SDK version will have its own docs XML entry
Edit the line above in each SDK version found in jdk.table.xml (if you want quick docs when targeting those versions in build.gradle). e.g. If you have Android SDK API 25 installed, you'd find a section to edit under <name value="Android API 25 Platform" />
Invalidate Caches / Restart after change!
File -> Invalidate Caches / Restart...
I also found this issue with Android studio 0.8.9 & 0.8.14, here's a simple solution:
File -> Invalid Caches/Restart -> Invalidate and Restart
Sometimes the documentation package may be missing or not up-to-date.
Try open the Android SDK manager(Tool->Android->SDK Manager) and install the 'Documentation for Android SDK' in the latest release, for now it's Android 5.0(API 21), then restart Android studio.
If this happens again, just invalidate the caches.
For android studio 3.4, all you need to do is go to sdk manager -> SDK Tools, check "Documentation for Android SDK" and click apply.
It will automatically update the jdk.table.xml to point to the source you have downloaded.
I found a solution.
Close the android studio and delete the c:\Users\xxx.AndroidStudioBeta\ (in my case)
Change the android sdk path name
Open the android studio, it will ask for the sdk path
Now you can change back the sdk path or using the new sdk path.
You will find Ctrl+Q will work fine. (Don't import old setting)
I think we need download the sdk document before set the sdk path to Android studio. But the Android studio should handle this case or give us a option to set it.
For a quick workaround edit /etc/hosts (or C:\Windows\System32\Drivers\etc\hosts) file and add the line:
0.0.0.0 developer.android.com
This will prevent it but you can comment it out when you need to fetch the latest or ones not cached or read the docs online.
UPDATE: From unknown exactly version, just simply download Android Documentation in SDK Manager could fix the problem. My 3.4.1 do so.
But I don't know whether older version could works as well or not.
I meet the same issue too,but I solved it just now. I used the Android Studio with SDK before I solved it,and then I download a Android Studio Zip without SDK,and run it,and the issue disappeared.
You can try it.
you can disable it, in Android Studio Preference
Android Studio -> Preference -> Editor -> General -> Code Completion -> Show the documentation pupup in XX ms

I have installed Android Studio, but its not locating Android SDK, I even tried to change the directory, but in vain.
Please check the photo to see the problem
go to the SDK manager just like in you image, press on edit, you'll get a setup wizard that will download the SDK files for you, if you think it's already been installed try to use the following directory
C:\Users'your_username'\AppData\Local\Android\Sdk
this is where the SDK is usually downloaded to, also note that the appdata folder is hidden in the file explorer

Error:Unable to locate adb within SDK in Android Studio
(31 answers)
Closed 4 years ago.
I have been trying to test my app on real device. I keep receiving error message that "unable to locate adb". I have the USB driver for my phone installed. Thank you for the help. The snap shot is shown below.
on your android studio at the top right corner beside the search icon you can find the SDK Manager.
view android SDK location (this will show you your sdk path)
navigate to file explorer on your system, and locate the file path, this should be found something like
Windows=> c://Users/johndoe/AppData/local/android (you can now see the sdk.)
Mac=>/Users/johndoe/Library/Android/sdk
check the platform tools folder and see if you would see anything like adb.exe (it should be missing probably because it was corrupted and your antivirus or windows defender has quarantined it)
close Android Studio, open the Task Manager and finish the ADB.exe process if it's running and then delete the platform tools folder
go back to android studio and from where you left off navigate to sdk tools (this should be right under android sdk location)
uncheck android sdk platform-tools and select ok. (this will uninstall the platform tools from your ide) wait till it is done and then your gradle will sync.
after sync is complete, go back and check the box of android sdk platform-tools (this will install a fresh one with new adb.exe) wait till it is done and sync project and then you are good to go.
If you are still having problems, you may need to set the Project SDK.
I hope this saves someone some hours of pain.
if using avast go for virus chest,will find adb,restore it by clicking right button..thats all,perfectly works
open Studio settings-->System settings --> Android SDK --> select SDK tool tab -->> select "Android SDK platform tool" and install
(I am using Android Studio 3.0.1)
I downloaded "SDK Platform-Tools" from
https://developer.android.com/studio/releases/platform-tools
Copied 'adb.exe' to C:\Users\user\AppData\Local\Android\Sdk\platform-tools.
Then I got no errors when running the app.
I also added C:\Users\user\AppData\Local\Android\Sdk\platform-tools\adb.exe to the exception list of my anti-virus tool
I use android studio in Windows 7 and i have AVG for antivirus. The first time you launch adb, AVG prompts you to add avg.exe in antivirus vault. If you accept, then you android studio dont have access to run adb.exe. So open
avg >> options >> Virus Vault >> Restore (select the adb file)
In Android Studio, Click on 'Tools' on the top tab bar of android studio
Tools >> Android >> SDK Manager >> Launch Standalone Sdk manager
there you can clearly see which platform tool is missing , then just install that and your adb will start working properly.In Image You Can see every thing
Due to some problem my adb.exe, was lost. My space of work suffered an electrical energy interruption, after that, I could not run or compile android programs.
Adb.exe is a file which should be located in your [android directory]/sdk/platform-tools. In my case, the file dissapeared, however the platform-tools was ther. My solution was as follows:
I changed the name directory of [android directory]/sdk/platform-tools towards platform-tools_OLD, in order to hide it for android studio without erase it.
In [android directory]/sdk there is a file SDK Manager.exe, ... I launched it.
A window of "Android SDK Manager" is shown, then, in the Tools folder I chose "Android SDK Platform Tools" and then, Install packages.
Enter to Android Studio
This was well for me
Else this will helps you
The ADB is now located in the Android SDK platform-tools.
Check your [sdk directory]/platform-tools directory and if it does not exist, then open the SDK manager in the Android Studio (a button somewhere in the top menu, android logo with a down arrow), switch to SDK tools tab and and select/install the Android SDK Platform-tools.
Alternatively, you can try the standalone SDK Manager: Open the SDK manager and you should see a "Launch Standalone SDK manager" link somewhere at the bottom of the settings window. Click and open the standalone SDK manager, then install/update the
"Tools > Android SDK platform tools".
If the above does not solve the problem, try reinstalling the tools: open the "Standalone SDK manager" and uninstall the Android SDK platform-tools, delete the [your sdk directory]/platform-tools directory completely and install it again using the SDK manager.
Hope this helps!
I had the same problem, and I solved it by doing:
(You should be connected to the internet)
click the logo of the SDK Manager
click Launch StandAlone SDK Manager (wait a moment)
if the dialog of the SDK manager shows, you click cexbox [Tools] and Install all packages
if the download is finished, you restart android studio and boot again..
After that, it should work.
Got it to work go to the local.properties file under your build.gradle files to find out the PATH to your SDK, from the SDK location go into the platform-tools folder and look and see if you have adb.exe. If not go to http://adbshell.com/downloads and download ADB KITS. Copy the zip folder's contents into the platform-tools folder and re-make your project.
I didn't need to update the PATH in the Extended Controls Settings section on the emulator, I left Use detected ADB location settings on. Hope this makes this faster for you !
I fixed this issue by deleting and inserting new platform-tools folder inside android sdk folder.
But it is caused by my Avast anti virus software. Where I can found my adb.exe in Avast chest. You can also solve by restoring it from Avast chest.
If you are using Anti-Virus, you can first check virus chest and restore from there. Otherwise, just go to your SDK Manager and install Android SDK Tools.
Check your [sdk directory]/platform-tools directory and if it does not exist, then open the SDK manager in the Android Studio (a button somewhere in the top menu, android logo with a down arrow), switch to SDK tools tab and and select/install the Android SDK Platform-tools.
Alternatively, you can try the standalone SDK Manager: Open the SDK manager and you should see a "Launch Standalone SDK manager" link somewhere at the bottom of the settings window. Click and open the standalone SDK manager, then install/update the
"Tools > Android SDK platform tools".
If the above does not solve the problem, try reinstalling the tools: open the "Standalone SDK manager" and uninstall the Android SDK platform-tools, delete the [your sdk directory]/platform-tools directory completely and install it again using the SDK manager.
Hope this helps!
I was installed new version of Android Studio but its not show the SDK .Any one help to solve this path issue.See this images.
Android studio configure that not show the SDk where i fix it path of sdk[enter image description here]1
Generally the stored path of android sdk in generally hidden.
So as per my experiences go as i say,
First allow your Pc to show hidden file.
Go to the following directory of your Pc or Lappy:
C:\Users\user\AppData\Local\Android
Here You can see your Sdks.
Open Android Studio
Press CTRL+ALT+SHIFT
In search bar type "sdk" .(Beside it you will see the android sdk location.Change it.)
Set the path of android sdk which you went into earlier in your lappy's directory shown above.

Here's the link..
And I ain't on Skype. Sorry😔
Thanks to all who give me suggestion.
Now its fix to reinstall complete android studio.
jdk file croup t or missing that why its show many problem.
I copy sdk file in another place and paste again when i reinstall my android studio its fix:) and no need to be download again sdk packages.
I have recently updated Android Studio from 2.2.3 to 2.3. Now can't see the option "Launch Standalone SDK Manager", which is useful to check for updates, google play services, etc.
It is a deprecated feature: https://code.google.com/p/android/issues/detail?id=235625 There is an option in Android Studio to "Show Package Details".
For manual SDK and AVD management, please use Android Studio.
For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager
See also: https://www.reddit.com/r/androiddev/comments/5x6adh/android_studio_23_is_now_available_in_the_stable/deg48lj/
Even I had this issue when I updated to Android Studio 2.3
Click on Configure on the bottom left side
Select the Check Box to Show Package Details on the bottom left side
Move between the different tabs as per your requirements.
Can't working on Android Studio 2.3.3
On Mac :
/Users/YourAccount/Library/Android/sdk/tools
click android, you'll see standalone SDK manager
On Windows :
C:\Productivity\android-sdks\tools
double click on android.bat, standalone SDK Manger will be launched (see image below).
As the standalone sdk manager has been deprecated in favor of studio builtin sdk manager, there's a workaround to get back the standalone sdk manager.
Step1.
Download command line sdk tools for your platform:
http://dl.google.com/android/installer_r24-windows.exe
http://dl.google.com/android/android-sdk_r24-windows.zip
the links refer to an old distribution intentionally (see note below).
Step2.
Copy the SDK Manager.exe, tools/android.bat and tools/lib/archquery.jar into your existing sdk to which android studio is currently being pointed.
Step3.
Run SDK Manager or tools/android.bat and you will get back your beloved standalone sdk manager while having latest android studio > 2.3
Note
if you download latest command line tools for sdk, you wont be able to find the archquery.jar which is required to run the standalone sdk utility.
In this latest version (2.3.1 and 2.3.1+), after some digging, I found a faster way to open AVD and SDK: In the welcome interface of Android Studio, after pressing CTRL+SHIFT+A, a search box will jump out, then you can input "AVD", the AVD manager will come out. To open SDK is the same way.
However, AVD does not work in the welcome interface but SDK works. If you want to use CTRL+SHIFT+A to quickly open AVD you must create a new project and open AVD in the project interface.
If you are a Xamarin user, you can install the Xamarin Android SDK Manager, available on the Visual Studio Marketplace which will give you an interface like this:
NOTE: The Xamarin SDK manager has to be accessed from visual studio, but it will (should) work on both windows and mac
You can open it from your SDK path which in my case is
C:\Users\Akshay\AppData\Local\Android\sdk
Double click on SDK Manager.exe and it will open standalone SDK manager, refer attached Screenshot.
When I open Android SDK Manager from Android Studio, the SDK Path displayed is:
\android-studio\sdk
I want to change this path. How do I do it?
From Android Studio 1.0.1
Go to
File -> project Structure into Project Structure
Left -> SDK Location
SDK location select Android SDK location (old version use Press +, add another sdk)
For projects default:
Close current Project (File->Close project)
You'll get a Welcome to Android Studio Dialog. In that:
Click on Configure -> Project Defaults -> Project Structure
Click on SDK Location in the left column
Put the path to the Android SDK in "Android SDK location" field.
(Example SDK location: C:\android-sdk; I have sub-folders like
add-ons, platforms etc under C:\android-sdk)
Click OK to save changes
Have fun!
Following steps were for older versions(<1.0) of Android Studio
In the middle column Click on Android SDK (with Android icon) OR click + on the top if you don't see an entry with Android icon.
Change SDK Home Path and select valid Target.
From the quick start window, choose Configure, then choose Project Defaults, and then choose Project Structure. Then on the left under Platform Settings choose SDKs. Then to the right of that choose the current android platform, mine was Android 4.2.2 Platform, and delete it using the red minus button at the top, then add a new android platform using the green plus button at the top and point it to your current SDK folder and that is it.
I Configured in this way
on
Welcome to Android Studio Screen
Click Configure Then
Project Defaults and then Project Structure
Then
Android SDK and Selected the path to my current location of Android SDK
Changing the sdk location in Project Settings will solve the problem partially. When Android Studio is used to download a new SDK, it will place the new SDK in the internal SDK folder (inside Android Studio).
Existing android developers will already have a large sdks folder (hereinafter referred to as external SDK folder) containing all the SDKs downloaded before Android Studio came around.
For Mac/Linux users though there is a good way out. Soft links!
Exit Android Studio and perform the following steps:
cp -r <Android Studio>/sdk/ <external SDK folder>/
cd <Android Studio>/
mv <Android Studio>/sdk/ mv <Android Studio>/sdk.orig
ln -s <external SDK folder>/ sdk
And we're good to go. Launch SDK Manager after starting Android Studio, watch as it discovers all your existing SDKs like a charm :).
EUREKA I found it!
With the current Studio 1.3 each project has a local.properties file where you can edit the SDK!
Here's how you can change the android sdk path in Android studio:
Open your required android project in Android studio
Click on the main project folder and press F4
Now click on "SDKs" under Platform Settings (Left hand side of the dialog box)
You should now see a plus sign on the top, click it and choose "Android SDK"
Now you would be asked to choose the required SDK folder
Select the required build target(if necessary) and click "ok"
Now you should see the new entry in the list of SDKs
Click "Modules" under Project Settings
Select your project folder and in the Dropdown for "Module SDK", select the new SDK entry and click "apply"
Now click "OK" and your done.
Note: If changes do not take effect, restarting android studio should fix the problem.
Make your life easy with shortcut keys ctrl+shift+alt+S
or
by going to file->project structure:
it will open this window, where you can select your SDK
Try this way i try in Android Studio 2.0
Step 1: File->Settings
Step 2: Settings->SDK options
Step 3: Click Edit option in Sdk Location
Step 4: Show "SDK Components Setup"
Step 5: Click on Three "..." in "SDK Components Wizad"
Step 6: Select your new SDK Path
I noticed that the latest version of Android Studio doesn't seem to have the option "SDKs" path that's mentioned in many of the answers. I'm guessing that disappeared in one of the updates, somewhere down the line?
The way i solved this issue (osx) was:
Go to Project Settings (Cmd + ;)
In SDK Location make sure you're pointing to the correct SDK location (typically /Applications/Android Studio.app/sdk) then hit Apply
Most important step - hit "Sync Project with Gradle files"
I wasn't doing Step 3 and that was throwing me off. After a sync all your source r belong to us....
goto menu File->Project Strucurt or key Ctrl + Alt + Shift + S
and example http://how-to-android-studio.blogspot.com/2014/11/set-sdk-location.html
You can also create the environment variable (in Windows) ANDROID_HOME to the location of the Android SDK and Android Studio will use that.
Above answers are pretty correct, but some times Android Studio, does not like to refresh after SDK path change, a quick solution is to make some change in you Build file, and click on Sync. It will refresh you project.
Happy coding... :)
While first installation There are two situations either you have pre-installed Android SDK if you had used it in past or you have nothing at all, At a time of installation Installer always ask user how you want to configure SDK with your studio.
You can simply give a path here or browse folder where sdk is available in local system. If you already have SDK, Another option as shown in below picture at Left down corner there is a nice option for download SDK, by clicking it you can download SDK with latest release right from there,You can also use third option see in right down corner setup Android SDK for me by clicking it you can step by step set your sdk.
Although you can also set it up when Android shows you list of available projects, a starting prompt window shown below
That's pretty easy, and also sometime if you want to change your SDK you can always change it right in your Android Studio from
On windows system
File --> Project Structure and then you will see SDK Location Option and from there you can set it up by providing a path or by browse it.
Or if you are on MAC system then from Platform settings.
In Android Studio 2.2.3 I think you can change default SDK location for all projects from the top menu:
File -> Project Structure...
A window like below shows up:
in windows press ctrl+shift+alt+s which will open project properties where you can find first option named SDK Location click on it and there you can change SDK path, JDK path and NDK path also
This may not be what you want, but being an eclipse user I had the same problem having duplicate sdk folders which were eating all my ssd space. Currently you can only change sdk path inside android studio project wide which is annoying. What I did instead was I copied all the previous android sdk files that I was using with eclipse to /Android Studio/sdk/ and then just changed the sdk path inside eclipse.
Now both android studio and eclipse are happy.
Here is some ways, as far as I know now.
Android Studio 3.3.2 (testing is OK)
method: 1
just following steps of the official docs, as bellow link shows
https://developer.android.com/studio/intro/studio-config#jdk
method: 2
following steps of the screen shortcuts, as bellow shows
method: 3
following steps of the screen shortcut, as bellow shows
Tap --> file --> close current project.
You'll Android Studio home page
Click on Configure -> Project Defaults -> Project Structure
Click on SDK Location in the left column and copy the path.
Paste the path in My computer --> Right Click -> Properties -> click on Advanced system settings -> Environment variables and change the android home path.
click on 'OK' to save the session.
Add tools and platforms tools in path and save the changes.
Open command prompt[window+R] and type adb + enter.
In Android Studio you can set the general Android SDK path in the file: %Home%.AndroidStudio2.1\config\options\jdk.table.xml
Click on File menu.
Select Project Structure.
Edit the path in SDK Location text box.
From the next time Android Studio will use this location for all your projects.
N.B.: Avoid having spaces in the path as it may sometimes lead to issues.
This is how its done,in Android Studio for windows
Done
For Android Studio 3.1.2:
Tools>> SDK Manager>> Edit "Android SDK Location" to new location
After that, Set environment variable $ANDROID_HOME to your new SDK location
I had the same problem, but with the sdk path pointing to a mounted drive. I found, that simply quit Android Studio, unmount the device and restart Android Studio made it ask for the sdk location, because it had none (Android Studio Beta 0.8.7).
Therefore I guess if you just quit Android Studio, delete \android-studio\sdk or move it somewhere else and start Android Studio again, it should ask for the sdk location aswell.
Though many of the above answers serve the purpose, there is one straight forward thing we can do in project itself.
In Eclipse, go to Window->Preferences, select "Android" from left side menu. On the right panel you will see "SDK Location". Provide the path here.
Good luck.
In Android studio 1.2.2 you can simply changes project based SDK,
Steps:
Right click on Module and select Open module setting or press F12
Select SDK location from left hand side
Now you can change SDK location as well as JDK location from this page
When I ran into trouble with this on Android Studio 3.1.4 the solution was to go into the app dropdown on my project, then Edit Configurations > Defaults > JAR Application where there is a JRE box on the initial Configuration tab. Setting that to my JRE path solved the problem for me.
Simple Answer Work For Sure...
Step 1: Right Click On The Project>> Select Open Module Setting -->
Step 2: Select SDK Location From the Right Side below image
Step 3: Now browse the SDK location from your computer as show below...
Step 4: Click on OK.
I'm guessing from the responses that people aren't understanding your question... If I'm right in that you want to have ~\Desktop\github\ then changing the SDK location isn't what you're after.
From Android Studio 3.2.1:
From the new project dialog, choose
Configure -> Preferences -> Tools -> Terminal -> Start Directory
Put the folder you want as your project default in the field.
e.g. Mine is set to
~/Desktop/github/
since all my work is in
~/Desktop/github/
Just go to
(Main Menu) File > "Sync Project With Gradle Files"
click ok on the popup, it will change your sdk directory.
