创建清单
以下是设备管理示例清单的摘录：
<receiver android:name="packageName.DeviceAdminReceiver子类"
android:permission="android.permission.BIND_DEVICE_ADMIN"
android:label="设备管理器广播接收">
<meta-data android:name="android.app.device_admin"
android:resource="@xml/device_admin(跟下面配置文件相同就行)" />
<intent-filter>
<action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
</intent-filter>
</receiver>
res/xml新建一个device_admin.xml配置文件（跟元数据一样）
<?xml version="1.0" encoding="utf-8"?>
<device-admin xmlns:android="http://schemas.android.com/apk/res/android">
<!--获取管理器权限-->
<uses-policies>
<force-lock/>
<limit-password />
<watch-login />
<reset-password />
<wipe-data />
<expire-password />
<encrypted-storage />
<disable-camera />
</uses-policies>
</device-admin>
通过代码调起授权
final DevicePolicyManager dpm = (DevicePolicyManager) context.getSystemService(Context.DEVICE_POLICY_SERVICE);
final ComponentName name = new ComponentName(context, DeviceAdminReceiver.class);
if (dpm == null) {
return;
}
if (!dpm.isAdminActive(name)) {
Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, name);
context.startActivity(intent); //这里可替换成接受返回值
}
授权后就可以使用DevicePolicyManager的管理API了
