当我运行我的应用时，无论是在设备上还是在模拟器上，我都会在Android Studio日志中收到一系列（红色）"Could not find class"消息。该应用程序运行正常。我的设置有什么问题？我使用gradle 2.1.0。
这是日志：

答案 0 :(得分：1)
您获得的日志是正常的。它们只代表从您的代码 有条件 引用的类。因此，它们是否存在并不重要。
找不到它们，因为它们不存在于您的设备或运行应用程序的模拟器上。
为什么它们不存在？因为它们是在较新的Android版本中引入的。
从日志中提取您的第一堂课，例如：
找不到类'android.util.ArrayMap'
ArrayMap是在API level 19中引入的，可能是你在旧版本上运行你的应用程序。
额外的东西：
由于应用程序运行正常，您可以忽略这些消息。由于缺少类而导致问题的唯一一次是当您尝试执行依赖于这些类的代码时。在这种情况下，例如对于ArrayMap，您可以使用android.support.v4.util.ArrayMap而不是常规android.util.ArrayMap
