I have following problem:
I try to use SupportMapFragment from com.google.android.gms.maps.SupportMapFragment which is part of Google Maps Android
Some of the solutions described here did not work for me. Others did, however they produced warnings on runtime and javadoc was still not linked. After some experimenting, I managed to solve this. The steps are:
Install the Google Play Services as recommended on Android Developers.
Set up your project as recommended on Android Developers.
If you followed 1. and 2., you should see two projects in your workspace: your project and google-play-services_lib project. Copy the docs folder which contains the javadoc from to libs folder of your project.
Copy google-play-services.jar from to 'libs' folder of your project.
In google-play-services_lib project, edit libs/google-play-services.jar.properties . The in doc= should point to the subfolder reference of the folder docs, which you created in step 3.
In Eclipse, do Project > Clean. Done, javadoc is now linked.
