设备管理应用程序的实现（Device Administration ）

Android 2.2 introduces support for enterprise applications by offering the Android Device Administration API.

从Android2.2 起，Android官方就提供了设备管理API，我们可以通过这个API实现远程删除数据、设置锁屏密码等系统级别的操作。

具体详见：http://developer.android.com/guide/topics/admin/device-admin.html

下面就是设备管理应用程序开发的简化实现步骤：

1.创建MyAdmin的广播接受者继承DeviceAdminReceiver

AndroidManifest.xml

<receiver android:name=".MyAdmin"><meta-data android:name="android.app.device_admin"android:resource="@xml/my_admin" /><intent-filter><action android:name="android.app.action.DEVICE_ADMIN_ENABLED" /></intent-filter></receiver>

MyAdmin.java

package com.alex.mobilesafe.receiver;import android.app.admin.DeviceAdminReceiver;public class MyAdmin extends DeviceAdminReceiver {}

2.创建XML文件：res/xml/my_admin.xml

<?xml version="1.0" encoding="utf-8"?><device-admin xmlns:android="http://schemas.android.com/apk/res/android">        <uses-policies>                <limit-password />                <watch-login />                <reset-password />                <force-lock />                <wipe-data />        </uses-policies></device-admin>

3.注册广播接受者为admin设备

DevicePolicyManager manager = (DevicePolicyManager) getSystemService(DEVICE_POLICY_SERVICE);ComponentName mAdminName = new ComponentName(this, MyAdmin.class);if (!manager .isAdminActive(mAdminName)) {Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN,mAdminName);startActivity(intent);｝

4.使用DevicePolicyManager

锁屏并设置锁频密码

DevicePolicyManager manager =                     (DevicePolicyManager) context.getSystemService(Context.DEVICE_POLICY_SERVICE);manager.resetPassword("123", 0);manager.lockNow();

远程删除数据

DevicePolicyManager manager =                     (DevicePolicyManager) context.getSystemService(Context.DEVICE_POLICY_SERVICE);manager.wipeData(0);
