E/dalvikvm:找不到上课

Question

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

我看到的唯一LogCat错误是:

我正在努力理解这些错误的根源.

Answer 1

您收到的日志是正常的。它们只是表示从您的代码有条件引用的那些类。所以，它们存在与否并不重要。

找不到提到的类，因为它们在您的设备或运行应用程序的模拟器上不存在。

为什么它们不存在？因为它们是在较新的 Android 版本中引入的。

从日志中选择您的第一堂课，例如：

找不到类“android.util.ArrayMap”

ArrayMap 是在API 级别 19中引入的，可能您正在旧版本上运行应用程序，这就是记录错误的原因。然而它们是无害的。
