Robospice Proguard Obfuscation causes for requests to "fail"

Question

I am using Robospice + Spring for Android. It works fine even with Proguard shrinking the code, but when I turn on obfuscation request complete successfully (log says Notifying 1 listeners of request success notifying null). But it seems that the listener is getting onRequestFailed instead of onRequestSuccess? Why would that be, is there something with my config file (attached below)?

Answer 1

When obfuscation fails, you will often see warnings in the log. In eclipse select, in the logcat view, "all messages" then filter by warnings (orange).

You will see things like :

VRFY : Couldn't find class XXX or couldn't find superclass of class XXX.

You will see which classes couldn't be found, and then be able to add them to your proguard conf file.
