Device Manager is the ability to clear data, and lock screen and so on operations

Here we are going to intercept by SMS blocker (broadcast receiver) and then by SMS content,

Here's how it's done:

The first thing to do is to create a class to inherit Deviceadminreceiver

and register it in the manifest file.

Android:name= ". Adminrecever "
android:description= "@string/sample_device_admin_description"
Android:label= "@string/sample_device_admin"
android:permission= "Android.permission.BIND_DEVICE_ADMIN" >
Android:name= ""
Android:resource= "@xml/device_admin_sample"/>

<action android:name= ""/>

Note that there is a reference to an XML file

Create an XML folder under the Res directory

Then the

<device-admin xmlns:android= "Http://" >

Copy it in.

In the end, it can be manipulated in the activity.
