I\'m trying to make jacoco create a code coverage report for my android test project. I have the following in build.gradle:

Now (Oct 2015) you can use it as android team has fixed the bug.

android {
    ...
    buildTypes {
        debug {
            testCoverageEnabled true
        }
    }
    ...
    dependencies{
        androidTestCompile 'com.android.support.test:runner:0.4.1'
        // Set this dependency to use JUnit 4 rules
        androidTestCompile 'com.android.support.test:rules:0.4.1'
        // Set this dependency to build and run Espresso tests
        androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
        // Espresso-contrib for DatePicker, RecyclerView, Drawer actions, Accessibility checks, CountingIdlingResource
        androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.1'
    }
}

Then just use ./gradlew createDebugCoverageReport.
