1、创建特定广播接受者DeviceAdminReceiver

public class MyDeviceAdminReceiver extends DeviceAdminReceiver{}

2、定义安全策略

@xml/device_admin_sample<device-admin xmlns:android="http://schemas.android.com/apk/res/android"><uses-policies><limit-password/>限制最短密码长度<watch-login/>监视登录次数<reset-password/>重置密码<fore-lock/>强制锁屏<wipe-data/>清除数据<expire-password/>密码有效期<encrypted-storage/>加密存储设备<disable-camera/>禁用照相机</uses-policies></device-admin>

3、清单文件配置

<receiverandroid:name="Receiver路径"android:description="@string/描述"android:label="@string/标签"android:permission="android.permission.BIND_DEVICE_ADMIN"><meta-dataandroid:name="android.app.device_admin"android:resource="@xml/device_admin_sample"/><intent-filter><action android:name="android.app.action.DEVICE_ADMIN_ENABLED"</intent-filter></receiver>

4、使用超级管理员

// 设备安全策略服务DevicePolicyManager manager = (DevicePolicyManager)context.getSystemService(Context.DEVICE_POLICY_SERVICE);manager.lockNow();// 锁屏manager.resetPassword("111", 0);// 重置密码manager.wipeData(DevicePolicyManager.WIPE_EXTERNAL_STORAGE);// 清除数据

5、安全设备管理器激活设置

Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);// 超级管理员组件名称intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN,new ComponentName(this, MyDeviceAdminReceive.class));intent.putExtra(DevicePolicyManager.ETRA_ADD_EXPLANATION,"这里是激活界面的说明内容");startActivity(intent);// 判断设备是否激活manager.isAdminActive(new CompontentName(this, MyDeviceAdminReceive.class));

6、取消激活

先判断设备是否激活manager.removeActiveAdmin(new CompontentName(this, MyDeviceAdminReceive.class));// 卸载应用Intent intent = new Intent();intent.setAction("android.intent.action.DELETE");intent.addCategory("android.intent.category.DEFAULT");intent.setData(Uri.parse("package:"+getPackageName()));startActivity(intent);
