        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

could anyone let me know what i have problem? or could you provide me some sample configuration with android and cobertura?

The cobertura plugin is attempting to add the ‘java’ plugin, which is incompatible with the android plugin. The authors of the cobertura plugin will have to update their plugin to be compatible with Android projects.

Issue #82 has been created against the Cobertura plugin for this problem.

I’m not sure how to proceed with a fix though. The plugin currently assumes that certain things exist such as a test task and a sourceSets.main property. When I apply the android plugin without the java plugin, these things don’t appear to be present.

If you’ve got ideas, please follow up in the Gradle plugin issue.

Thanks,
