I know this question has asked before, but I am really surprised, after trying so hard. I have not enabled to work alarm on android emulator. I have tried all codes of this forum but in vain. Even I download a sample code still it did not work. please help me guys I am sending you my all code. Can anyone tell me "do alarm bell rings on android emulator"? If yes then what is problem in my code? I tested same code for API level 4 and 10. Both did not work. Even I create 2 different projects but in vain.
AndroidAlarmService:
package com.exercise.AndroidAlarmService;
import java.util.Calendar;
import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
public class AndroidAlarmService extends Activity {
private PendingIntent pendingIntent;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button buttonStart = (Button)findViewById(R.id.startalarm);
Button buttonCancel = (Button)findViewById(R.id.cancelalarm);
buttonStart.setOnClickListener(new Button.OnClickListener(){
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent myIntent = new Intent(AndroidAlarmService.this, MyAlarmService.class);
pendingIntent = PendingIntent.getService(AndroidAlarmService.this, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 10);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
Toast.makeText(AndroidAlarmService.this, "Start Alarm", Toast.LENGTH_LONG).show();
}});
buttonCancel.setOnClickListener(new Button.OnClickListener(){
public void onClick(View arg0) {
// TODO Auto-generated method stub
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
// Tell the user about what we did.
Toast.makeText(AndroidAlarmService.this, "Cancel!", Toast.LENGTH_LONG).show();
}});
}
}
MyAlarmService:
package com.exercise.AndroidAlarmService;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;
public class MyAlarmService extends Service {
@Override
public void onCreate() {
// TODO Auto-generated method stub
Toast.makeText(this, "MyAlarmService.onCreate()", Toast.LENGTH_LONG).show();
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
Toast.makeText(this, "MyAlarmService.onBind()", Toast.LENGTH_LONG).show();
return null;
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
Toast.makeText(this, "MyAlarmService.onDestroy()", Toast.LENGTH_LONG).show();
}
@Override
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
Toast.makeText(this, "MyAlarmService.onStart()", Toast.LENGTH_LONG).show();
}
@Override
public boolean onUnbind(Intent intent) {
// TODO Auto-generated method stub
Toast.makeText(this, "MyAlarmService.onUnbind()", Toast.LENGTH_LONG).show();
return super.onUnbind(intent);
}
}

I was also getting same problem. But I installed my application on mobile then the alarm bell was working.
Then I came to know alarm bell is not working on emulator. So no need to worry about this. You have to try on your mobile. Its working fine.
