Как обрабатывать уведомления о нажатии?

Question

У меня есть этот код для уведомлений, который работает, но всякий раз, когда я нажимаю на уведомление, приложение закрывается, я не знаю почему. Я хочу, когда я нажимаю на уведомления для его отмены, я также хочу, чтобы он был приурочен, если это возможно, можете ли вы мне помочь?

Вот код:

package egypt.interfaceAct; 

import android.app.Activity; 
import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.Intent; 
import android.os.Bundle; 
import android.widget.Toast; 

public class Notifications extends Activity { 

    NotificationManager nm; 
    int uniqueID = 13393; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
     Bundle programNum = getIntent().getExtras(); 
     final String body = programNum.getString("Activity"); 
     final String startTime = programNum.getString("Start"); 
     final String endTime = programNum.getString("End"); 
     nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE); 
     nm.cancel(uniqueID); 
     String notify = body + "Start at: " + startTime + " to: " + endTime; 
     Intent intent = new Intent(this,ProgramsList2.class); 
     PendingIntent pi = PendingIntent.getActivity(this, 1, intent, 0); 
     //String body = (String) ((TextView)parent.getChildAt(position)).getText(); 
     String title = "Egypt On The Go"; 
     //String time = body + "\n start at:" + startTime+ "\n end at:" + endTime.get(position); 
     Notification n = new Notification(R.drawable.egypt, notify, System.currentTimeMillis()); 
     n.setLatestEventInfo(this, title, notify, pi); 
     n.defaults = Notification.DEFAULT_ALL; 
     nm.notify(uniqueID, n); 
     n.flags = Notification.FLAG_AUTO_CANCEL; 
     //Intent i = new Intent(this, ProgramsList2.class); 
     //startActivity(i); 
     finish(); 
    } 
} 

Вот LogCat может быть, это поможет:

Ju dging следом стека, это выглядит как это проблематично код:

Bundle programNum = getIntent().getExtras(); 
final String progNum = programNum.getString("ProgNum"); 

Вам необходимо пройти необходимое дополнительное в Intent вы установили на уведомления.
