安卓 4.0.3 ScrollingTabContainerView NullPointerException

Question

我们的 Android 应用程序随机崩溃(很难重现该问题)并显示以下堆栈跟踪。当设备的方向从 logcat 日志从纵向更改为横向时，就会看到这一点。此问题也出现在 Android 4.0.3 版本的设备上。所以想检查它是否是 4.0.3 的已知问题？从代码中不确定如何调试此问题，因为堆栈跟踪完全是 Android 平台，不涉及 App 代码。

Answer 1

我真的不知道这个错误是从哪里来的。我通过更改

修复了它

    <item name="android:windowActionBarOverlay">false</item>

进入

    <item name="android:windowActionBarOverlay">true</item>

我的 Android v15 主要风格。对于这个 Android 版本，它让我的应用程序变得不那么漂亮了，但这没关系。我希望这只是一个 4.0.3 错误，我有 6 台其他 Android 版本的平板电脑运行良好。
