Question

"android.permission.WRITE_SETTINGS" has signature level,but a normal app can also use it. so who can tell me something about it. thanks.

Answer 1

Basically, the android.permission.WRITE_SETTINGS allows an application to read or write the system settings.

You can request this permission in your app like this:

<uses-permission android:name="android.permission.WRITE_SETTINGS" />

(or like this for Android 6.0 only)

<uses-permission-sdk-m android:name="android.permission.WRITE_SETTINGS" />
