java.lang.NoSuchMethodError：android.os.HandlerThread.quitSafely

Question

设置= Android Studio 2.3.3和Robolectric 2.4和gradle 3.2

我正在为AAAService类编写单元测试用例。以下是AAAService类。 但是，在调用HandlerThread类的quitSafely（）时，会从测试文件中得到启发。

dput(l2)
list(a = structure(list(v1 = c(3L, 5L, 2L, 1L, 4L), v2 = c(8L, 
6L, 7L, 5L, 4L)), class = "data.frame", row.names = c(NA, -5L
)), b = structure(list(v1 = c(9L, 18L, 17L, 5L, 13L), v2 = c(47L, 
48L, 6L, 25L, 12L)), class = "data.frame", row.names = c(NA, 
-5L)))

下面是单元测试文件。 onCreate（）方法已成功执行，但是onDestry（）在“ mAcsThread.quitSafely（）”行中给出了例外；

public class AAAService extends Service {
private HandlerThread mAcsThread = null;
private Handler mSigHandler = null;
private Handler mCcsHandler = null;
private Handler mAcsHandler = null;
private Handler mDecoupledFunctionHandler = null;

public AAAService() {
}

public AAAService(Context context) {
        mContext = context;
}

public void onCreate() {

  mSigHandler = new Handler(mAcsThread.getLooper());
        mCcsHandler = new Handler(mAcsThread.getLooper());
        mAcsHandler = new Handler(mAcsThread.getLooper());
   mDecoupledFunctionHandler = new Handler(mAcsThread.getLooper());
}

public void onDestroy() {
 mAcsThread.quitSafely();
}
}

异常堆栈

@RunWith(RobolectricTestRunner.class)
public class AAAServiceTest {
 @Test
    public void onTest() throws Exception {

    objAcsService.onCreate();

    objAcsService.onDestroy();
  }
}
