 import android.content.pm.PackageManager;
 import android.content.pm.PermissionGroupInfo;
 import android.content.pm.PermissionInfo;
 import android.os.Bundle;

             String [] usesPermissionsArray=packageInfo.requestedPermissions;
             for (int i = 0; i < usesPermissionsArray.length; i++) {

                  //得到每个权限的名字,如:android.permission.INTERNET
                  String usesPermissionName=usesPermissionsArray[i];
                  System.out.println("usesPermissionName="+usesPermissionName);

                  //通过usesPermissionName获取该权限的详细信息
                  PermissionInfo permissionInfo=packageManager.getPermissionInfo(usesPermissionName, 0);

                  //获得该权限属于哪个权限组,如:网络通信
                  PermissionGroupInfo permissionGroupInfo = packageManager.getPermissionGroupInfo(permissionInfo.group, 0);
                  System.out.println("permissionGroup=" + permissionGroupInfo.loadLabel(packageManager).toString());

                  //获取该权限的标签信息,比如:完全的网络访问权限
                  String permissionLabel=permissionInfo.loadLabel(packageManager).toString();
                  System.out.println("permissionLabel="+permissionLabel);

                  //获取该权限的详细描述信息,比如:允许该应用创建网络套接字和使用自定义网络协议
                  //浏览器和其他某些应用提供了向互联网发送数据的途径,因此应用无需该权限即可向互联网发送数据.
                  String permissionDescription=permissionInfo.loadDescription(packageManager).toString();
                  System.out.println("permissionDescription="+permissionDescription);
                  System.out.println("===========================================");
             }

         } catch (Exception e) {
             // TODO: handle exception
         }


     }

 }

main.xml如下:

 <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="查看Android应用所需权限(uses-permission)"
         android:layout_centerInParent="true"
     />

 </RelativeLayout>

PS:

该示例本身是不需要任何权限的
