I am using retrofit2.0 in my app with simpleframework.xml library.
retrofit2.0
simpleframework.xml
The problem is when I run the app without proguard it works fine however
try adding these below lines in your proguard file. It should solve your problem
-dontnote retrofit2.Platform -keepattributes Signature -keepattributes Exceptions
and remove these below lines
-dontwarn retrofit2.** -keep class retrofit2.** { *; }
