How to remove application or activity from recent task

Question

I am using Broadcast receiver to start my activity..

Broadcast Receiver Called Using Alarm Manager:

AlarmManager mAlarmManager = 
    (AlarmManager) getSystemService(Context.ALARM_SERVICE);

Intent mIntent = 
    new Intent(this, BrodcastRec.class);

PendingIntent mPendingIntent = 
    PendingIntent.getBroadcast(
        this, 
        0, 
        mIntent, 
        PendingIntent.FLAG_CANCEL_CURRENT);

mAlarmManager.set(AlarmManager.RTC_WAKEUP, miliSecounds, mPendingIntent);

In my Broadcast Receiver

@Override
    public void onReceive(Context context, Intent intent) {
        Intent intentObject = new Intent(context.getApplicationContext(), ActicityWhichIWantToKill.class);
        intentObject.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
        intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
        context.startActivity(intentObject);
}

In The ActivityWhichIWantToKill

i will create the function to finishOrKill

closeApplication()
{
  finishAffinity();
}

Solution Which I have Tried

1.Adding In Manifest.XML

<Application>
...

<activity android:name=".activity.ActicityWhichIWantToKill"
            android:excludeFromRecents="true"
            android:noHistory="true"></activity>
....
</Application>

Adding Flags In Intent Object

intentObject.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

Use Intent

    Intent homeIntent = new Intent(Intent.ACTION_MAIN);
    homeIntent.addCategory( Intent.CATEGORY_HOME );
    homeIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    startActivity(homeIntent);
