Handling Screen ON using BroadcastReceiver

This post will explain with an example how to receive the Screen On event.
Firstly create an application with the following details:

activity_screen.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".ScreenActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

</RelativeLayout>

ScreenActivity.java

package com.samples.screenonreceive;

import android.os.Bundle;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.view.Menu;
import android.widget.Toast;

public class ScreenActivity extends Activity {
    // Broadcast Receiver to Screen On
    private BroadcastScreenReceiver mBroadcastScreenReceiver;
    // Specify that the Application should receive Screen On
    private IntentFilter mIntentFilter;
   
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_screen);
       
        // Register
        mBroadcastScreenReceiver = new BroadcastScreenReceiver();
        mIntentFilter = new IntentFilter(Intent.ACTION_SCREEN_ON);
        registerReceiver(mBroadcastScreenReceiver, mIntentFilter);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.screen, menu);
        return true;
    }
   
    @Override
    public void onDestroy() {
        super.onDestroy();
        // Unregister
        if (mBroadcastScreenReceiver != null) {
            unregisterReceiver(mBroadcastScreenReceiver);
        }
    }
   
    /**
     * Broadcast Receiver to Screen ON
     * @author Tanvi Surve
     *
     */
    private class BroadcastScreenReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {
            // Make this Toast appear on Screen On
            Toast.makeText(getApplicationContext(), "Screen is ON", Toast.LENGTH_LONG).show();
        }
       
    }

}



Run the application:

Use the highlighted button on the emulator to make the screen ON and OFF. On the Screen ON, you will get a Message as "Screen is ON".
