问题
I am getting following exception in different areas of my project. And worst thing is I have no idea what it is... I do not have com.b.a.c.b package in my project. I tried searching on web but still, I am not understanding what is causing this exception.
This exception is thrown on onCreate() method (I guess) after an Intent call from another Activity.
Note: I am using gson 2.2.4 with POJO method, just before this I got this exception, I was facing error in JSON creation with same kind of value "a", "b", "c", etc... instead of POJO variable names. I resolved it using @SerializedName("") annotation over all variable names in POJO class.
following is error log:

Disable proguard and than you will see that error will explain itself, you can do it from gradle file.
