激活设备管理器

一.激活设备管理器账户，

1.设置完成界面 按钮的点击事件
public void activeAdmin(View view) {
Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
ComponentName mDeviceAdminSample = new ComponentName(this,MyAdmin.class);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN,mDeviceAdminSample);
intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,"95%的用户都开启了. 开后好处多多");
startActivity(intent);
}

2.public class MyAdmin extends DeviceAdminReceiver {

}

3.清单文件中

<receiver
android:name="com.itheima.mobilesafe.receiver.MyAdmin"
android:description="@string/sample_device_admin_description"
android:label="@string/sample_device_admin"
android:permission="android.permission.BIND_DEVICE_ADMIN" >
<meta-data
android: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.掌控哪些权限 res目录下建个xml文件夹device_admin_sample.xml
<device-admin xmlns:android="http://schemas.android.com/apk/res/android">
<uses-policies>
<reset-password />
<force-lock />
<wipe-data />
</uses-policies>
</device-admin>
