Firebase Analytics-CrashReport的NPE

Question

我刚刚迁移到Firebase Analytics 9.0.0，尝试在emulator api10/x86上启动应用程序时，服务会引发以下异常。有没有办法解决这个问题？

代码只不过是一种活动，包括：

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FirebaseCrash.log("onCreate: " + getClass().getSimpleName());
}

Answer 1

只是对道格所说的进行了小小的修正。非播放设备不支持Firebase崩溃报告。特别是Firebase Analytics和其他一些Firebase产品确实支持非播放设备。

Answer 2

不幸的是，在没有Play服务的设备或模拟器上使用Firebase是不受支持的用例。崩溃报告将无法初始化，当应用程序启动时，您将在logcat中看到一条这样的消息。然而，如果您在初始化失败后调用方法时也看到崩溃，那么这似乎是一个我们应该纠正的问题。

听起来你通过抑制异常做了最好的事情，但我不想让你经历这些，所以我将把它作为反馈传递给团队。
