Question

我们在生产应用程序中遇到以下异常，但没有提及应用程序类。很难找出问题的出处，而且我们也无法在设备中复制。

Fatal Exception: java.lang.NullPointerException: Attempt to read from field 'int android.view.View.mViewFlags' on a null object reference

我看到了一些与我的问题相似的链接，但这也无济于事。以下是我看到的链接：

Android ViewGroup crash: Attempt to read from field 'int android.view.View.mViewFlags' on a null object reference

getting NullPointerException: Attempt to read from field 'int android.view.View.mViewFlags' - Android animation

如果有人遇到同样的问题并有解决方案，请告诉我。

如果需要更多信息，也请告诉我。

谢谢您的时间。：）

尝试从空对象引用中读取字段“ int android.view.View.mViewFlags”
