我对发布 Android 应用程序非常陌生，并且在发布前报告中确实收到了“Google Pixel 3”设备的以下错误：致命异常：UserFacing7。
引起：com.google.android.apps.gsa.tasks.c：java.lang.NullPointerException：尝试在空对象引用上调用虚拟方法'boolean java.lang.String.equals（java.lang.Object）'
我试图分析和重现这个问题，但没有成功。这似乎是一个与 java 相关的问题，从 Unity 上下文中我不知道如何解决和解决这个问题，并且真的需要帮助。
有趣的是，我有同样的应用程序，用另一种语言同时发布，没有任何错误。
这是堆栈跟踪：
