查看Android应用所需权限(uses-permission)

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 {@Overrideprotected 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
