如何通过Android.mk在AOSP Java和Robolectric中获得代码覆盖率

Question

我正在用AOSP编写应用程序。我需要为此应用进行单元测试。为此，我使用了robolectric。该应用程序和测试使用make（Android.mk）进行编译。我需要一个代码覆盖率报告，并且不知道获取此方法。我只找到了使用gradle的解决方案，我们在项目中没有使用过。

有人知道如何获得代码覆盖率的解决方案吗？

public class Example extends Service
{
   @Override
   public void onCreate() {
     Log.d("Example"," onCreate");
   }

   public boolean foo(){
     Log.d("Example"," foo");
     return true;
   }

   @Override
   public IBinder onBind(Intent intent) {
     return new ExampleBinder();
   }

    public class ExampleBinder extends Binder {
      // Returns service object
      public Example getService() {
        return Example.this;
      }
    }
}

@RunWith(RobolectricTestRunner.class)
@Config(shadows = {ShadowBinder.class, manifest=Config.NONE)
public class ExampleRoboTest {
    private static final String TAG = "ExampleRoboTest";
    private ServiceController<Example> controller;
    Example service;

    @Before
    public void setUp() {
        controller = Robolectric.buildService(Example.class);
        service = controller.create().get();
    }

    @After
    public void tearDown() {
    }

    @Test
    public void foo()
    {
      assertTrue(service.foo());
    }

}

使用Android Build System和Java Code Coverage Library，请尝试以下操作：
