How to attach Android Source to Eclipse

By | December 1, 2017

I’ve previously had success attaching the Android Source to Eclipse by following Finn Johnsen’s instructions here.

However this approach seems to have stopped working:

samuel-josephs-computer-4:android-sources samueljoseph$ git checkout origin/froyo-release
Previous HEAD position was 1de4a2c... am 62619392: Merge "Fix leak when keylock is recreated."
HEAD is now at adba66b... This class no longer exists.

There was a more recent blog here which had some pre-organized source for Eclair, but nothing since.

There are also some StackOverflow posts from 2008 (older than both the above), e.g.

What is the current guidance for accomplishing this?


There is an Eclipse plugin called Android Sources that installs the sources up through Gingerbread. I haven’t tried it recently.


There is a updated guide. So, you don’t need to install an eclipse plugin for this.

Here is the link

Snip from above Link:

follow below steps if you already have downloaded Android sources

  1. Head into eclipse, and press F3 over some android source you’re missing, like Activity. And get this pesky window, which we all hate:

  2. Click Attach Source, choose External Folder, and choose the core/java in the base folder.


For Android 4+ here’s a tutorial for attaching sources to eclipse.


  1. First download the source and javadoc from sdk manager.Download these.
  2. Goto Your_Project>>Android XXX, Right-Click on android.jar and select Properties.

  3. Point the sources path as Java Source Attachment>>Location Path by clicking on External Folderenter image description here

  4. Point the reference path as Javadoc Location>>Javadoc Location Path by clicking on Browseenter image description here

Now you can browse sources like this:

Here’s a tutorial:

  1. Make sure you have installed/downloaded the Android source for the appropriate Android SDK API version.

    1.1 Check the API version you have specified in Eclipse for Android/Project Build target:

    project Properties/Android

  2. Open project Properties/Java Build Path and click the “Link Source…” button on the Source tab:

    project Properties/Java Build Path

  3. Point to where you have installed the Android SDK, expand the “sources” folder, select the appropriate source API version (and click “OK”):

    select source API version

  4. Next…:

    Link Source

  5. Important step is to exclude the whole linked source from building. Otherwise we could have some duplicate source errors plus who wants to build the whole Android source when we have jars already! So, click “Add…”, type in *, click “OK” (and then “Finish”):

    exclude everything

  6. Verify everything is configured correctly:


Desired result — linked platform source w/o side effects:


I hope this helped 🙂


The best way is as below.

  1. Update Android SDK Manager, including source of the version you need.

  2. click on Any class like activity, if source is properly attached, it will open the Activity class.

  3. If it is not opening up, then click on the attach source and can give source path as above.

  4. Source path will be like android-sdk-windows\sources\android-17

This will help you to add source for android SDK


You can do it this way …. hover or copy paste any class_name which is provided from android , just press F3 you will find a Attach_a_source tag there , click in it & here browse your android-sdk folder
and from it just pick source folder because inside it , every android files resides .
