查看Android应用所需权限(uses-permission)

http://www.tuicool.com/articles/zq2meq

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; /** * Demo描述: * 查看Android应用所需权限(uses-permission) * * 参考资料: * 1 http://blog.csdn.net/bage1988320/article/details/6740292 * 2 http://blog.csdn.net/hjd_love_zzt/article/details/12238301 * Thank you very much * * 备注说明: * 在Demo中的代码注释是以android.permission.INTERNET权限 * 为例子对各属性进行了详细说明 * */ 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
