Android Alarm Manager Example | How to Start and Stop Alarm Manager in Android | Notification Manager Example in Android

Hello Friend,

Today I am going to share code for "Create Alarm Manager in Android". And Notification Manager with sound and vibration.


EDIT: stop was not working


1)MainActivity-


package com.manish.alarmmanager;

import java.util.Calendar;

import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

/**
 *
 * @author manish
 *
 */

public class MainActivity extends Activity implements OnClickListener{

Button btnStartAlarm,btnStopAlarm;
Context context;
static PendingIntent pendingIntent;
static AlarmManager alarmManager;

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


Intent intentsOpen = new Intent(this, AlarmReceiver.class);
intentsOpen.setAction("com.manish.alarm.ACTION");
pendingIntent = PendingIntent.getBroadcast(this,111, intentsOpen, 0);
alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);


btnStartAlarm=(Button)findViewById(R.id.button1);
btnStopAlarm=(Button)findViewById(R.id.button2);

btnStartAlarm.setOnClickListener(this);
btnStopAlarm.setOnClickListener(this);

}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(v==btnStartAlarm){
fireAlarm();
}
if(v==btnStopAlarm){
stopAlarm();
}
}
public void fireAlarm() {
/**
* call broadcost reciver
*/
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 10000, pendingIntent);


}
public void stopAlarm(){
alarmManager.cancel(pendingIntent);



}


}


3)OutPut.java

package com.manish.alarmmanager;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;

public class OutPut extends Activity {
TextView textmessage;
String stringValue;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_output);

textmessage = (TextView) findViewById(R.id.textView1);

Intent intent = getIntent();
stringValue = intent.getStringExtra("content");
textmessage.setText(stringValue);
System.out.println(stringValue);

}
}

4)Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
