ant emma BUILD FAILED

I try to run android unit test with code coverage. I'm using the Android example NotePad.

These are the commands I used:

cd <main project folder>
android update project --path .
android update test-project -m <full path to main project> -p <full path to main project>\tests
cd ./tests
ant emma debug install test

the tests runs successfully. But in the end emma can't generate the report html File.

Here you get the commandline output of ant emma debug install test

BUILD FAILED
C:\Android\android-sdk\tools\ant\build.xml:1313: [EMMA v2.0.5312] report: no valid input data files have been specified

Total time...

I would like to post the C:\Android\android-sdk\tools\ant\build.xml but the file is to long. But i guess it is always the same...

Any ideas?

Solution

The command ant emma debug install test is only successfull on a rooted device or on an emulator (otherwise permission denied).

Useful hints:

If you're using SDK 13 or older you've to use ant coverage instead of ant emma debug install test
One of the last output lines show you where the report file has been saved
If you use Windows you have to add the Path of the android.bat (normally /tools) and the path of the ant.bat (depending where you installed Ant; If you use Eclipse with ADT it is normally there: /plugins/org.apache.ant.../bin) to the PATH Variable (you may also have to do this with a diffrent OS)
