Going through the problem from the last few weeks but still, can't find a solution. Searched a lot on internet but all in vain because such issues are hard to describe when you don't know which part of the code is creating a problem.
Once in a while, my app freezes the mobile UI especially when the app is in the background and I want to clear the recent apps opened. Now the real problem is I am not able to track the root cause of the problem.
My app total code size is around 1 Gb, and APK size is 6MB is that creating a problem?
I got the following exception in the case of ANR:
