Question

I have a eclipse workspace with 3 subprojects

• myMp3TagBusineslogic (lib that can be used for android and for j2se)
• myMp3TagActivity_Plugin (android activity that uses myMp3TagBusineslogic and that can be launched by MyFIles, OIFilemanager and other apps: A gui to edit/view mp3-tags )
• myMp3Tag_Test_Activity (some android activity used to test myMp3TagActivityPlugin by just executing Intent mp3Tagger = ... ; startActivity(mp3Tagger);

Reason for this layout: seperate guiplugin from testcode.

my qestion: how is it possible to debug the code of myMp3TagActivityPlugin by executing myMp3TagTestActivity?

What I tried so far:

• Set a breakpoint in onCreate of myMp3TagActivity_Plugin and started debugging myMp3Tag_Test_Activity
  • effect: debugger does not stop in myMp3TagActivity_Plugin. Plugin is executed correctly.
• Add plugin and myMp3TagBusineslogic to buildpath of myMp3Tag_Test_Activity
  • effect: cannot start myMp3Tag_TestActivity: myMp3TagActivityPlugin class not found.

Edit: Update and solution for those who have the same problem:

• as the comment below states the buildpath that includes the plugin into the test was not complete and therefore the testactivity crashed. Correct buildpath
  • add projects plugin
  • add projects busines
  • order and exports check plugin (i forgot before)
  • order and exports check busines (i forgot before)
• however after uninstalling the plugin.apk from the device and debugging the test.apk (that now really contains the plugin-code and a combined manifest) the debugger still does not stop in the plugin-code.
• after adding Debug.waitForDebugger() to the plugin-source and debugging the test.apk i finally could debug the plugin source.

You could try below method, might well work.

Add a call Debug.waitfordebugger() in myMp3TagActivity_Plugin entry point. Execute myMp3Tag_Test_Activity. Now the activity will show waiting for debugger to connect.
Then find the port of the process myMp3TagActivity_Plugin , usually starts from 8600 as you can see below.

Then Right click myMp3TagActivity_Plugin project, debug as -> Debug Configurations -> Double click remote java app change port in connection properties to match above(8600) -> Debug.
