My main question is why i'm getting above exception and error? that too in different Android API levels.

Answer Source

this problem can be related to multidex support for your application. Android Version < 21 do not support Multidex by default. You need to enhance your application. I followed the following instructions to resovle this problem for my applications API Level < 21
