2_deviceadmin步骤 :
1.创建 MyAdmin 的广播接受者继承 DeviceAdminReceiver

<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>

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>

2.获取IDevicePolicyManager

Method method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class);IBinder binder = (IBinder) method.invoke(null,new Object[] { Context.DEVICE_POLICY_SERVICE });mService = IDevicePolicyManager.Stub.asInterface(binder);

3.注册广播接受者为admin设备

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