How to use EMMA code coverage in android

Question

I\'m new to EMMA, I don\'t know how to use this for android system. Can anyone please give a sample for using this with android. Thanks a lot.

I've only been able to get emma working using ant. If you've got an ant build set up then you can run:

ant emma debug install
ant emma debug install test

The first is run in your project directory, the second from your test directory. See the docs for more details: http://developer.android.com/guide/developing/building/building-cmdline.html

If you don't have an ant build.xml file already you can see how to generate one from your current project here: http://developer.android.com/guide/developing/projects/projects-cmdline.html

The sad part is this will only work on the emulator or a rooted device. This is because the coverage file gets generated in a folder that requires root. I also needed to modify the android-sdk/tools/ant/build.xml file to copy the file on my rooted device elsewhere so I could pull it off. I modified the emma block of the xml to be the following:

    
        
            WARNING: Code Coverage is currently only supported on the emulator and rooted devices.
