 Hi all,

In my application i have created pending intent which calls another
activity (after 20mins of alarm off) with the help of alarm manger. It
should happen each time for each new pending intent or when I call
that activity.
But when i create one pending intent and after few mins again create
new pending intent ,then the last one overlap the other previous
pending intents and start specified activity only for ones for the
last pending intent.

I want  that each time i create any pending intent it should start
specified activity after 20 mins of it's alarm off time.How it can be
done ?
here is my code:--


Intent intent = new Intent(getApplicationContext(),AlarmCall.class);

                                        intent.putExtra("PolicyNo3",policyNo2);

                                        intent.putExtra("BarcodeNo",barcode_no);
                                        
Constants.pendingResultList.put(policyNo2, barcode_no);
        
System.out.println(Constants.pendingResultList.containsKey(policyNo2));

                                        PendingIntent pendingIntent =
PendingIntent.getBroadcast(getApplicationContext(),
0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
                                        AlarmManager alarmManager = 
(AlarmManager)
getSystemService(ALARM_SERVICE);

                                long timedely = System.currentTimeMillis() + 
(20*60*1000);
        
alarmManager.set(AlarmManager.RTC_WAKEUP,timedely,
                                            pendingIntent);









////// Below is the code of ALarmCall.class






manger = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
                 Notification notification = new
Notification(R.drawable.icon,"Please upload
result",System.currentTimeMillis());
                 Intent startActivity1 = new Intent();
                        startActivity1.setClass(context, UploadTest.class);
                        startActivity1.setAction(UploadTest.class.getName());
                        startActivity1.putExtra( "PolicyNo4",policyNo3);
                        startActivity1.putExtra("BarcodeNo1",barcodeNo);
                        startActivity1.addFlags(
                        Intent.FLAG_ACTIVITY_NEW_TASK
                        | Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);

                 PendingIntent contentIntent = 
PendingIntent.getActivity(context,
0,startActivity1    ,Intent.FLAG_ACTIVITY_NEW_TASK);
                 notification.setLatestEventInfo(context, "HIV 
Pharmacy","Result of
Id- "+policyNo3,contentIntent);
                 notification.flags = Notification.FLAG_ONLY_ALERT_ONCE |
Notification.FLAG_SHOW_LIGHTS;
                 notification.ledARGB = Color.GREEN;
                 notification.ledOnMS = 1000;
                 notification.ledOffMS = 500;
                 notification.defaults = Notification.DEFAULT_SOUND |
Notification.DEFAULT_VIBRATE;
                 manger.notify(32, notification);
                 context.startActivity(startActivity1);




 Thanks to all.

 tt> Setting an alarm cancels any previous alarms that have the same intent 
as the new one.


In your code, the old and new intents only differ by their extras, which
are not considered (I believe).


What you could do is calculate the next point in time when an alarm is
needed, set one alarm, and when it goes off, figure out which of the
possible actions you need to perform.

 Thanks to all for your response,

I have solved that problem by passing unique id which is depend on
current time:-

        final int intent_id= (int) System.currentTimeMillis();

                                        PendingIntent pendingIntent =
PendingIntent.getBroadcast(getApplicationContext(),intent_id,intent,PendingIntent.FLAG_UPDATE_CURRENT);

        by this change code is working properly and each pending
intent starts
specified activity after 20 mins of it's alarm off time.

 That's really janky.  I'd strongly recommend only posting one alarm, for the
next event you have in time, and upon processing that post a new alarm for
the following event.  This is how  most apps work.  Your code here is really
problematic in how it manages its alarms -- for example if you have an alarm
scheduled for something, and the user changes that thing's time or deletes
it, how do you remove the alarm from the alarm manager?

1. baffling alert dialog listener behavior: how come local variables dont keep their data

Consider the following listener class, where I want to remember a
promptValue and return. But after invoking it from a dialog I get the
value as null when I expect it to be "hello"

public class PromptListener
implements android.content.DialogInterface.OnClickListener
{
   public String promptValue = null;
   public void onClick(DialogInterface v, int buttonId)
   {
      promptValue="hello";
   }
}


Here is how I use this call back with a dialog


public static String Prompt(String message, Context ctx)
{
   //load some kind of a view
   LayoutInflater li = LayoutInflater.from(ctx);
   View view = li.inflate(R.layout.promptdialog, null);

   //get a builder and set the view
   AlertDialog.Builder builder = new AlertDialog.Builder(ctx);
   builder.setTitle("Prompt");
   builder.setView(view);

   //add buttons and listener
   PromptListener pl = new PromptListener(view,ctx);
   builder.setPositiveButton("OK", pl);
   builder.setNegativeButton("Cancel", pl);

   //get the dialog
   AlertDialog ad = builder.create();

   //show
   ad.show();

   //How come the following is "null" ???
   //when it shoudl be "hello" on a button click
   return pl.prompt;
}

The last return I should have a "hello".

DOes the builder copy or cache the listener and its local variables??

Appreciate your help
