java - CoordinatorLayout 使用 IndexOutOfBoundsException 使应用程序崩溃

Question

我的应用程序因 CoordinatorLayout 中的 onLayout 函数发生崩溃(来自 Crashlytics，无法在本地重现):

由于我自己无法重现此内容并且有 6 个 Activity 与 CoordinatorLayouts 相关，我该如何进行调试？

编辑:看起来它将在 next support library release 中修复

Answer 1

我遇到了类似的问题，降级到较旧的 Android 支持库版本 (v24.1.1) 对我有用。这似乎是库中的问题，您可以在 Android 问题跟踪器中查看问题 here .

更新 1:似乎它将在下一版本的 Android 支持库 (v24.2.1) 中得到解决，谢谢 Daniel Rampelt更新

更新 2:24.2.1 已于今天发布，错误似乎已解决——至少我无法用当前版本重现它。 – PattaFeuFeu

更新 3:24.2.1 引入了新错误:post ——AAverin
