带有空活动的新项目会导致警告

Question

我目前正在开发一个应用程序，它应该向后兼容到API级别23 (Marshmallow)。不幸的是，即使使用自动生成的空活动，并且没有对项目进行任何进一步的更改，Logcat也提到了许多警告。不要误解我的意思:这个应用程序运行得很好，但是我还是想尽快处理这些警告。

单独研究这些警告不会产生任何效果，因为可用的答案通常是指源代码中的问题。由于我没有对自动生成的源代码做任何修改，这些答案没有帮助。

其他尝试：

• 重新启动应用程序
• 重新启动模拟器
• 清除数据
• 清除缓存
• 更改仿真器(与Nexus 10、Nexus 5X和自定义仿真器相同)
• 在最新的AndroidStudio3.0Beta 4中创建项目
• 在连接的设备上运行应用程序

在所有情况下，Logcat都提到以下警告：

问题

1. 这是一种已知的现象，还是我应该立即处理这些警告呢？
2. 由于我已经回顾了IDE的设置、构建过程和模拟器本身，我已经没有任何想法了。您将如何处理这些警告？

Answer 1

这是一种已知的现象，还是我应该立即处理这些警告呢？

所有这些都应该被忽视。

您将如何处理这些警告？

无视他们。

它们都不是来自您的Java代码。Android框架和底层子系统在日志消息中往往不必要地喋喋不休。
