如何使用 Android.mk 在 AOSP Java 和 Robolectric 中獲得代碼覆蓋率

Question

我正在 AOSP 中編寫應用程序。 我需要為此應用程序進行單元測試。 為此，我使用了 robolectric。 應用程序和測試使用 make (Android.mk) 編譯。 我需要一份代碼覆蓋率報告，但不知道如何獲得。 我只找到了使用 gradle 的解決方案，我們在項目中沒有使用它。

有人知道如何獲得代碼覆蓋率的解決方案嗎？

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());
    }

}
