Override Power button just like Home button

Well, i am Doing a stuff in which I want to disable all hard button of the device

Hard button like Power, Home, Volume up, Volume down, Search, Back.

I successfully override almost all buttons Here except Power

so i just want you people to see and please share some idea so that I can away with it

I am getting the long press Power keyevent in onDispatchKeyEvent(), sameway i wanted to catch short click of the same. Morever when pressing power i also tried to stop Screen off by getting the Broadcast of SCREEN_OFF and succeed to receive but not able to handle it.

Thanks.

Till i had created a RecieverScreen which recieves broadcast of Screen on/off

ReceiverScreen.java

public class ReceiverScreen extends BroadcastReceiver {
 
     public static boolean wasScreenOn = true;
 
     @Override
     public void onReceive(Context context, Intent intent) {
         if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
             // do whatever you need to do here
             wasScreenOn = false;
         } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
             // and do whatever you need to do here
             wasScreenOn = true;
         }
     }
 }
 

DisableHardButton.java

public class DisableHardButton extends Activity {
 
 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
 
     setContentView(R.layout.main);
     IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
     filter.addAction(Intent.ACTION_SCREEN_OFF);
     BroadcastReceiver mReceiver = new ReceiverScreen();
     registerReceiver(mReceiver, filter);
     }
 
 @Override
     protected void onPause() {
         // when the screen is about to turn off
         if (ScreenReceiver.wasScreenOn) {
             // this is the case when onPause() is called by the system due to a screen state change
             System.out.println("SCREEN TURNED OFF");
 
     } else {
         // this is when onPause() is called when the screen state has not changed
     }
     super.onPause();
 }
 
 @Override
 protected void onResume() {
     // only when screen turns on
     if (!ScreenReceiver.wasScreenOn) {
         // this is when onResume() is called due to a screen state change
         System.out.println("SCREEN TURNED ON");
     } else {
         // this is when onResume() is called when the screen state has not changed
     }
     super.onResume();
 }
 }
