Thank you Mark, I do know that I can you onStop method as it is supposed to be called when ever something else comes on to the screen (in this case the home page). But my situation is a little more complicated than that.
I have an address field and an option for gps[if its switched on]. But in the bottom portion of the screen I will be loading my results based on the location. Now since I have loaded the results using the onCreate, its doing so. So I changed it to do all those things in the onStart method so that the Activity life cycle goes on smoothly. Thanks for the suggestion because of which I went through my Activity's lifecycle to see how everything is going on. But since I started trying to log everything to see the activity life cycle, what I observed is that onStop method is not actually being called when I click on home button. Its being called as soon as i open my app again, which is not how I wanted it to do. The locationUpdates should stop the moment the user hits home button. The other thing is that I expected my stack to be as it is and as soon as I open my app after hitting on home button, the activity which I was previously in will be opened. But it restarted the app itself. This is what I observed in my app. Say I have a main activity A and another Activity B. I come to Activity B from Activity A. Then I click on home button. It closes the app but does not yet call onStop on B. Now I open my app and it now calls onStop on Activity B. It starts Activity A again. Now only when I click on button for activity B, it calls onRestart method on Activity B. So am I doing something wrong or is it supposed to work in that way or is it a bug?
