android中device Admin 应用-------就是获得手机的超级用户权限

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);
}
}
