This happens when I enable Proguard.

You should check your configuration for typos.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unknownclass) Note: there were 28 classes trying to access generic signatures using reflection.
You should consider keeping the signature attributes
(using '-keepattributes Signature').
(http://proguard.sourceforge.net/manual/troubleshooting.html#attributes) Note: there were 5 classes trying to access enclosing classes using reflection.
You should consider keeping the inner classes attributes
(using '-keepattributes InnerClasses').
(http://proguard.sourceforge.net/manual/troubleshooting.html#attributes) Note: there were 1 classes trying to access enclosing methods using reflection.
You should consider keeping the enclosing method attributes
(using '-keepattributes InnerClasses,EnclosingMethod').
(http://proguard.sourceforge.net/manual/troubleshooting.html#attributes) Note: there were 33 unkept descriptor classes in kept class members.
You should consider explicitly keeping the mentioned classes
(using '-keep').
(http://proguard.sourceforge.net/manual/troubleshooting.html#descriptorclass) Note: there were 1 unresolved dynamic references to classes or interfaces.
You should check if you need to specify additional program jars.
(http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclass) Note: there were 3 accesses to class members by means of introspection.
You should consider explicitly keeping the mentioned class members
(using '-keep' or '-keepclassmembers').
(http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclassmember) Warning:there were 4 unresolved references to classes or interfaces.
You may need to add missing library jars or update their versions.
If your code works fine without the missing classes, you can suppress
the warnings with '-dontwarn' options.

This line in my gradle build was causing problem.I actually dont need it ,and so i removed it ,and everything works well now.
"compile 'com.firebase:firebase-client-android:2.3.1'"
if i were to use firebase client ,i would have provided progaurd rules for it.
Also I do not need proguard rules for some of the firebase featues such as:
com.google.firebase:firebase-core:9.4.0,
com.google.firebase:firebase-crash:9.4.0,
com.google.firebase:firebase-config:9.4.0
Rest of those features, you will find on this link: https://firebase.google.com/docs/android/setup
