问题描述

当我触摸操作栏按钮时，我在Android应用程序中遇到锁定.我什至没有得到ANR对话.

我正在努力了解这些错误的根源.

I am struggling to understand the origin of these errors.

推荐答案

所获取的日志是正常的.它们只是表示有条件地从您的代码中引用的那些类.因此，它们是否存在并不重要.

The logs that you're getting are normal. They simply represent those classes that are referred from your code conditionally. So, it doesn't matter if they exist or not.

找不到提到的类，因为它们在您运行应用程序的设备或仿真器中不存在.

The mentioned classes are not found because they don't exist on your device or the emulator at which you're running the app.

为什么它们不存在?因为它们是在较新的Android版本中引入的.

Why don't they exist? Because they were introduced in newer Android versions.

例如，从日志中提取您的第一堂课:

Pickup your first class from the log for example:

找不到类'android.util.ArrayMap'

Could not find class 'android.util.ArrayMap'

ArrayMap是在 API级别19 中引入的，可能您是在较旧的版本上运行您的应用，这就是记录错误的原因.但是它们是无害的.

ArrayMap was introduced in API level 19, probably you're running your app on an older version, and that's why the error is logged. They are harmless however.
