MainActivity如下:

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;

public class MainActivity extends Activity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    getUsesPermission("cc.testusespermission");
  }

  private void getUsesPermission(String packageName){
    try {
      PackageManager packageManager=this.getPackageManager();
      PackageInfo packageInfo=packageManager.getPackageInfo(packageName, PackageManager.GET_PERMISSIONS);
      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
