title: What is the meaning of Application is doing too much work in its main Thread?
body: <p>I am making a simple game. </p>
  
  <p>1st screen is splash screen with just 2 images, 1 progress bar and a background image.</p>
  
  <p>2nd screen is Options choose from different levels / options of games. It has few TextFields, Spinner Items , 2 images and 1 background. These images and background images are same as of splash screen.</p>
  
  <p>From the options screen there is two ways to proceed with New Activity in game either choose "3x3"(MainActivity.class Activity) or 4X4(bigmain.class Activity). Both these activities are playing screen and contains 1 same image and a grid layout fitted with few ImageViews.</p>
  
  <p>Both MainActivity and bigmain has onClick() method of grid layout.
  All the further game processing like checking if anywone wins or not, different methods to invoke on different player's turn. So both of them has lots of code and all in single java class file. Is this the reason ?
  If so then how to overcome it. I am attaching my logcat report when I install app in my phone through adb. See the bold text.</p>
