AndroidStudio：JaCoCo代码覆盖率报告的覆盖率为0％

Question

I've recently brought code coverage into my project. It creates a report, which I can view, and it seems to be working great.

The only problem is it is missing my tests - I don't have GREAT code coverage right now, but it reports 0% coverage for all classes and other files.

I can see the tests being run, and can see them passing, but they aren't being counted.

My configuration is:

android {
    compileSdkVersion 18
    buildToolsVersion '21.1.1'
    ...
     debug {
            minifyEnabled false
            testCoverageEnabled = true
        }
}

Answer 2

It's working (again) with

androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
