Android取得超级管理员权限 Android

1.创建一个空的接收者:
package com.example.mobilesafe.receiver; import android.app.admin.DeviceAdminReceiver; public class AdminReceiver extends DeviceAdminReceiver{ }

2.配置使用到的超级管理员功能: 在res/xml下新建一个xml文件,填入如下代码(需要什么功能填什么功能,不写全): "http://schemas.android.com/apk/res/android">

3.在清单文件中配置权限的描述,标题,以及组件全限定名. "com.example.mobilesafe.receiver.AdminReceiver" android:label="@string/sample_device_admin" android:description="@string/sample_device_admin_description" android:permission="android.permission.BIND_DEVICE_ADMIN"> "android.app.device_admin" android:resource="@xml/adminpolicy" /> "android.app.action.DEVICE_ADMIN_ENABLED" />
4.使用超级管理员的功能: //清除数据功能 DevicePolicyManager dpm = (DevicePolicyManager) context.getSystemService(Context.DEVICE_POLICY_SERVICE); dpm.wipeData(0); abortBroadcast(); //锁屏功能 DevicePolicyManager dpm = (DevicePolicyManager) context.getSystemService(Context.DEVICE_POLICY_SERVICE); dpm.lockNow(); abortBroadcast();
5.弹出激活超级管理员的界面:

Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN); ComponentName cn = new ComponentName(this, AdminReceiver.class); //组件名字 intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, cn); intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,"可以实现清除数据,锁屏功能"); startActivity(intent);

6.移除超级管理员权限: DevicePolicyManager dpm = (DevicePolicyManager) context.getSystemService(Context. DEVICE_POLICY_SERVICE ); ComponentName cn = new ComponentName( this , AdminReceiver. class ); //组件名字 dpm .removeActiveAdmin( cn ); //移除操作
