android - Google Analytics - 测试中的 NullPointerException

Question

我在 Travis 构建服务器上的 Robolectric 测试中得到以下 NPE，我无法查明原因。我无法在本地重现此问题。

有人知道是什么原因导致 onServiceConnected 被调用吗？这可能会帮助我查明问题所在。据我所知，这是一个 Google Play 服务 - Google Analytics 问题。

据我所知，我没有在任何地方为我的单元测试初始化​​ GA。我有一个通用的“假”分析跟踪器，只要运行测试就会使用它。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，该跟踪器是在应用程序的 onCreate 中创建的:

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

如果这是相关的，它会破坏 Java 1.7.0_u55 的盒子。

编辑:

我今天在失败测试的日志中看到以下内容。我不确定这是崩溃的原因。可能会提供一些见解。

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

看起来像是 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)。我暂时恢复到 v3。

Answer 1

Akeem 的解决方案适合我。

这是我用于 Robolectic 3.0 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");
