How the actual Alarm app is working?

Question

I am looking to know how the actual alarm app popup the dialog box on exact time without any activity in background of it. If you could please see my this post for the exact solution i am looking for but answer to this question is much appreciated.

Code for popup

public void onCreate(Bundle savedinstance)
{
    super.onCreate(savedinstance); 
    //alarmsound = MediaPlayer.create(this, R.raw.wewillrock);
    alarmsound = new MediaPlayer();

        try {
            if(db.getAlarmCount()!=0)
            {
                Cursor alarmcursor = db.getAlarmdetails(this);
                if(alarmcursor!=null)
                {
                    alarmcursor.moveToFirst();
                    String alarmTonepath = alarmcursor.getString(alarmcursor.getColumnIndex(GinoClockDatabase.AL_RINGTONEPATH)); 
                    alarmsound.setDataSource(alarmTonepath);    
                    alarmsound.prepare();
                }
                db.close(); 
            }
            db.close();
        } catch (IllegalArgumentException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IllegalStateException e) {
            // TODO Auto-generated catch block0
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        alarmsound.start();

    ((Activity)Global.context).finish();
    setContentView(R.layout.reminderpopupmessage);  
    settingViews(); 
}
private void settingViews() {
    yes = (Button) findViewById(R.id.btnReminderyes);
    no = (Button) findViewById(R.id.btnReminderno); 
}
@Override
public void onClick(View v) {

    switch(v.getId())
    {
    case R.id.btnReminderyes:
        alarmsound.stop();
        Intent splashscreen = new Intent(ReminderPopupMessage.this,SplashScreen.class);
        startActivity(splashscreen);
        ReminderPopupMessage.this.finish();
        break;
    case R.id.btnReminderno:
        alarmsound.stop();
        ReminderPopupMessage.this.finish();
        break;
    } 
}

I am looking more than a month for this solution but couldn't find the solution. I think i have asked more than 5 question about this alarm functionality. I hope i will get answer now.

Thanks for your help guys.

And in your xml file, set the Activitiy to be a dialog theme, in order to get the popup layout like this: android:theme="@android:style/Theme.Translucent.NoTitleBar" — Carnal, Jul 09 '12 at 14:31

Alright, I see your problem. In order to get rid of the background activity when displaying the popup, use this in your AndroidManifest.xml for the activity popping up as the alarm:

<activity android:name=".AlarmPopup" android:theme="@android:style/Theme.Dialog"
              android:clearTaskOnLaunch="true" android:launchMode="singleInstance" 
              android:finishOnTaskLaunch="true" excludeFromRecents="true"/>

I don't really understand you. After the popup comes up? You pressed the home button and then when you start the application again it goes to that popup? You should implement then a close button on the alarm with the finish() method in order to remove it from the stack. Don't really understand what you mean. – Carnal Jul 10 '12 at 07:12
