Stop Timer on return to previous Activity

I have created a timer that starts timing on a handleClick() and continues timing throughout the app. When I return to the firstActivity I would like the timer to stop in the onResume(). however whenever I return to the firstActivity I get the following error below. How do I solve this?
Error
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean com.example.warrenedy.julyfinal.TimeTracker2.isTracking()' on a null object reference
Code Below
#Override

Toast.makeText(this, "Onresume call", Toast.LENGTH_SHORT).show();

Trouble expanding image in samsung s8

As screen height of samsung s8 is quite large.My images in LoginUI(attached) were looking small.I calculated phone's height in dp programmatically.
DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
float dpHeight = displayMetrics.heightPixels / displayMetrics.density;
Log.d("checkheightdp",dpHeight+"");
It gave me dpheight 692.So,I create a separate layout-h692dp and put my layout with increased image height.For some reason,It is still picking the default layout and hence image not expanding.
My code:

Finally I got my answer,why creating a separate height layout was not working.
Though screen height of samsung s8 is 692 dp,but 25dp is not available as It is used by system UI.
Apparently it was stated in developer.android.com.
The Android system might use some of the screen for system UI (such as the system bar at the bottom of the screen or the status bar at the top), so some of the screen might not be available for your layout.
Therefore,subtracting 25 dp from 692 gives 667dp.Creating layout-h667dp worked.
I went to this post.

Getting incoming calls for an hour only using Twilio

I have implemented Twilio in my android app for outgoing and incoming calls. But I'm facing an issue while getting incoming call with the background service. The issue is that I get calls in first 30-40 mins only. After sometime phone stops getting incoming calls. I tried so much. Please respond me soon. I'm sharing code with you too.
I get token from a background service which generates token after a time period.
