I am trying to debug a simple Android app with Eclipse 3.7.1. I attachted the Android SDK sources so I can step through the code of the SDK also. I can set unconditional breakpoints on code of the SDK but not conditional breakpoints. I get the following error message if I try:
Conditional Breakpoint Error
Conditional breakpoint has compilation error(s).
Unable to compile conditional breakpoint - missing java Project context
Conditional breakpoints on by own sources work, however.
The only relevant search result on the topic I found suggests to convert the project containing the third party jar into a Java project. But I do not know how to do this for the Android SDK, i.e. how to add it as an Eclipse project at all. (Would that be even sensible?)
To fix this error, create a new Java project for the Android library your project uses. Link the sources of the Android library delivered by the SDK to that project. Exclude everything (*), otherwise warning and error messages will flood your log! Attach the source code from that new project to the «android.jar» your project uses. That's it.
I wrote a more step-by-step solution here.
