Google Analytics - 测试中的NullPointerException

Question

我在Travis构建服务器上的Robolectric测试中获得了以下NPE,我很难找到原因.我无法在本地重现此问题.

有人知道是什么原因导致onServiceConnected被调用？这可能有助于我找出问题所在.据我所知,这是Google Play服务 - Google Analytics问题.

据我所知,我没有在任何地方初始化GA进行单元测试.我有一个通用的"假"分析跟踪器,可以在运行测试时使用.为了以防万一,我在我的假跟踪器的构造函数中添加了以下行,该构造函数在应用程序的onCreate中创建:

GoogleAnalytics.getInstance(context).setAppOptOut(true);

如果这是相关的,它将打破Java 1.7.0_u55的盒子.

编辑:

我今天在测试失败的日志中看到了以下内容.我不确定这是导致坠机的原因.可能会提供一些见解.

E/GAV3: Thread[GAThread,5,main]: Google Analytics is shutting down.

看起来像SQLite和GA的问题？

另一个更新:

有关更新,请参阅链接的github问题(https://github.com/robolectric/robolectric/issues/1075).我暂时回到v3.

Answer 1

Akeem 的解决方案对我有用。

这是我在 Robolectic 3.0 中使用的，它有一些变化：

import org.robolectric.RuntimeEnvironment;
import org.robolectric.Shadows;
import org.robolectric.shadows.ShadowApplication;

ShadowApplication shadowApplication = Shadows.shadowOf(RuntimeEnvironment.application);
shadowApplication.declareActionUnbindable("com.google.android.gms.analytics.service.START");
