Custom error handling with retrofitting when obfuscated with proguard gives java.lang.reflect.UndeclaredThrowableException
Have written error handling for modification. The code works fine when minifyEnabled false
. When I enable proguard I get the following exception
12-17 10:14:07.688 18568-19041/com.mobility.cariq.carscore W/System.err﹕ java.lang.reflect.UndeclaredThrowableException

I am new to using proguard and modification. I cannot figure out how to handle the exception.

It looks like it UnauthorizedException
is a checked exception (continues from Exception
, not RuntimeException
), which means you need to declare a clause throws
on all of your service interfaces.
interface MyService {
@GET("/")
Something doSomething() throws UnauthorizedException;
}
