Updates: As far as i'm able to figure out is that i'm using Basic authentication in my factory class of Retrofit , i think problem lies in Basic authentication, but i am unable to fix it.

Any possible solution ?

Answer 1

I'm posting late answer but solution was to use https://github.com/JakeWharton/retrofit2-rxjava2-adapter And setup factory class of retrofit accordingly

Note: rxjava 2 only support retrofit 2 vice versa

Source : experience

Answer 2

Try adding

-keep class rx.internal.util.unsafe.** {
    *;
 }

to your proguard file.
