最近我根据IDE的建议将Android Studio从0.4.2更新到0.5.0,将Android Gradle Plug-In从0.7.2更新到0.9.0.项目运行并安装良好,但是当我按下Build-> Rebuild Project时,它会抛出一个错误,停止重建.消息选项卡中出现以下错误:

Information:See complete output in console
Error:Execution failed for task ':projectName:proguardDebug'.
> java.io.IOException: Please correct the above warnings first.

以下是控制台中描述的问题:

:projectName:proguardDebug

我正在尝试为我的演示者编写一个简单的Robolectric测试,该测试使用Firebase数据库和Firebase Auth.但每次我尝试启动测试时,都会抛出IllegalStateException.

java.lang.IllegalStateException: FirebaseApp with name [DEFAULT] doesn't exist. 
    at com.google.firebase.FirebaseApp.getInstance(Unknown Source)
    at com.google.firebase.FirebaseApp.getInstance(Unknown Source)
    at com.google.firebase.auth.FirebaseAuth.getInstance(Unknown Source)

我的测试非常简单

@RunWith(RobolectricTestRunner.class)
@Config(constants = BuildConfig.class)
public class LoginPresenterTest {
    private LoginPresenter presenter;
    private LoginMvpView view;

    @Before
    public void beforeEachTest() {
        presenter = new LoginPresenter();
        view = new LoginFragment();
    }

    @Test
    public void attachView_shouldAttachViewToThePresenter() {
        presenter.attachView(view);
        assertSame(presenter.getMvpView(), view);
    }
}

在我的演示者构造函数中,我只是获取Firebase实例.

public LoginPresenter() {
        this.firebaseAuth = FirebaseAuth.getInstance();
        this.database = FirebaseDatabase.getInstance().getReference();
    }

有没有办法将Robolectric与Firebase一起使用？
