Android Notification

Learn to create Notification.

Open the project folder and create a new folder "raw" in the res folder. Put a .mp3 file which you want to use as notification sound.

Do the following coding in the MainActivity.java file.

package com.codingredefined.notification;

import android.media.AudioManager;

import android.media.MediaPlayer;

import android.os.Bundle;

import android.app.Activity;

import android.app.Notification;

import android.app.NotificationManager;

import android.app.PendingIntent;

import android.content.Context;

import android.content.Intent;

import android.view.Menu;

public class MainActivity extends Activity 

{

private static final int HELLO_ID=1;

MediaPlayer mMediaPlayer;

@Override

protected void onCreate(Bundle savedInstanceState) 

{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

String ns=Context.NOTIFICATION_SERVICE;

NotificationManager mNotificationManager=(NotificationManager)getSystemService(ns);

int icon=R.drawable.ic_launcher;

CharSequence tickerText="Hello!";

long when=System.currentTimeMillis();

Notification notification=new Notification(icon, tickerText, when);

//Vibrate on Notification

notification.defaults=Notification.DEFAULT_VIBRATE;

long[] vibrate={0,100,200,300};

notification.vibrate=vibrate;

//Glow LED

notification.defaults=Notification.DEFAULT_LIGHTS;

notification.ledARGB=0xff00ff00;

notification.ledOnMS=300;

notification.ledOffMS=1000;

notification.flags=Notification.FLAG_SHOW_LIGHTS;

//Activate notification

Context context=getApplicationContext();

CharSequence contextTitle="My Notification";

CharSequence contextText="Hello World!!!";

Intent notificationIntent=new Intent(this,MainActivity1.class);

PendingIntent contentIntent=PendingIntent.getActivity(this, 0, notificationIntent, 0);

notification.setLatestEventInfo(context, contextTitle, contextText, contentIntent);

mNotificationManager.notify(HELLO_ID, notification);

//Sound

mNotificationManager.notify(HELLO_ID, notification);

mMediaPlayer=new MediaPlayer();

mMediaPlayer=MediaPlayer.create(this,R.raw.abc);

mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

mMediaPlayer.setLooping(true);

mMediaPlayer.start();

Thread t=new Thread()

{

@Override

public void run()

{

try

{

Thread.sleep(5000);

}

catch(Exception e){}

mMediaPlayer.stop();

}

};

t.start();

}

@Override

public boolean onCreateOptionsMenu(Menu menu) 

{

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

}

The following output will be obtained.
