I want to know how to update the UI when a new value comes up. I'm using this code, and for this i have to launch the activity again to get the new results or values. Here is my code below:

 final Handler handler = new Handler(Records.this.getActivity().getMainLooper());
            handler.post(new Runnable() {
                @Override
                public void run() {
                    tempchart.invalidate();
                }
            });

Where tempchart is the View (chart) in which i'm going to show the realtime values

use broadcast receivers to get the updates. – Mohd Asif Ahmed Jul 12 '17 at 10:31
broadcast receiver only tells when there is change in value. but i want to show the actual data that i'm receiving on real time – Jul 12 '17 at 10:33
use services, and hit the api with some time limit, say 2mins, and get the refresh data. – Mohd Asif Ahmed Jul 12 '17 at 10:34
where does the data come from ? – yanivtwin Jul 12 '17 at 10:35

Refreshing the view can be as simple as a `setText` with a `TextView`. You will have to check the documentation of the Chart View you're using – Alberto S. Jul 13 '17 at 06:49
