[RK3399][Android7.1] 调试笔记 --- Sending non-protected broadcast ...

Platform: RK3399
OS: Android 7.1
Kernel: v4.4.83

使用自定义的广播，然后用命令行测试的时候出现如下warning:

原因：

系统对自定义广播做了保护限制，对广播做了保护限定之后，只有一定权限的用户才可以使用。否则用一次就会打印一次warning，并且保存异常信息到文件中。

解决方法：

framework/base目录：
diff --git a/core/res/AndroidManifest.xml b/core/res/AndroidManifest.xml
index 45086c0..d8f3a9a 100644
