How to update "Mobile data" state using a BroadcastReceiver

This BroadcastReceiver will trigger anytime "Mobile data" disconnects or connects.

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

this.registerReceiver(mDATAStateChangedReceiver,new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));

}

@Override
public void onBackPressed() {
    
    unregisterReceiver(mDATAStateChangedReceiver); // this will unregister Receiver
    this.finish(); // this will finish ThisActivity
    super.onBackPressed();
}

private BroadcastReceiver mDATAStateChangedReceiver = new BroadcastReceiver()
{

    @Override    public void onReceive(Context context, Intent intent)
    {
        boolean mobileDataEnabled = false; // Assume disabled
        try {
            Class cmClass = Class.forName(cm.getClass().getName());
            Method method = cmClass.getDeclaredMethod("getMobileDataEnabled");
            method.setAccessible(true); // Make the method callable
            // get the setting for "mobile data"
            mobileDataEnabled = (Boolean)method.invoke(cm);
        } catch (Exception e) {
            // Some problem accessible private API         }
        if(mobileDataEnabled == false){//mobile data is disconnected, do whatever you want here);}
else
{info10.setText(//mobile data is connected, do whatever you want here); }

    }
};
}
