No i already have activity started. I only want to send data to another activity that has already been started before.... — Mehdi, Sep 29 '14 at 09:51
Please clarify your requirement. Is there some service running that keeps on updating data?? Or it is just one activity? — Pr38y, Sep 29 '14 at 09:51
Its just an activity.......some method will call so it will update new data ,..... — Mehdi, Sep 29 '14 at 09:52
If you want to send data to the previous activity then you can use putExtra and the finishing current activity previous activity will receive updated data. — Pr38y, Sep 29 '14 at 09:54

Use Handler to send data to another activity

  public static Handler handler;

handler=new Handler(new Handler.Callback() {

    @Override
    public boolean handleMessage(Message msg1) {

        //-- retreiving data
        String data=msg.obj.toString();
        return false;
    }
});

Now pass data from activity 1

 Message msg=new Message();
msg.obj="Test Message";//Pass any type of value
Activity2.handler.sendMessage(msg);

Cheers

I think what you are looking for is sending and receiving broadcast messages between activities. Refer:

How to send and receive broadcast message

Or This tutorial. http://hmkcode.com/android-sending-receiving-custom-broadcasts/

What if i use Async task??? – Mehdi Sep 29 '14 at 10:34
How to do in my both activities? – Mehdi Sep 29 '14 at 10:36
If you use AsyncTask, you will have to create the Activity2 inside the doInBackground method, by passing the context from Activity1 to it as arguments. I am not sure you would be able to do this, have never tried. If you can, well, you're welcome :) – A Nice Guy Sep 29 '14 at 10:37
