View the permissions required by the Android app (uses-permission)

MainActivity is as follows:

Package cc. testusespermission; import android. app. activity; import android. content. pm. packageInfo; import android. content. pm. packageManager; import android. content. pm. permissionGroupInfo; import android. content. pm. permissionInfo; import android. OS. bundle;/*** Demo Description: * view the permissions required by the Android app (uses-permission) ** reference: * 1 http://blog.csdn.net/bage1988320/article/details/6740292 * 2 http://blog.csdn.net/hjd_love_zzt/article/details/12238301 * Thank you very much ** Note: * The code comment in the Demo is android. permission.

Main. xml is as follows:

<RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android" xmlns: tools = "http://schemas.android.com/tools" android: layout_width = "match_parent" android: layout_height = "match_parent"> <TextView android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: text = "view permissions required by Android applications (uses-permission)" android: layout_centerInParent = "true"/> </RelativeLayout>

PS:

This example does not require any permissions.
