Helo Krish,

Zunächst einmal, achten Sie auf diese Warnung. Es ist sehr wichtig, dass Sie den Code sauber halten und organisiert und mit Dubletten

Proguard returned with error code 1. See console  
[2016-07-29 13:16:13 - samAPPSampleAndroid] Note: there were 2641 duplicate class definitions. 
[2016-07-29 13:16:13 - samAPPSampleAndroid]  You should check if you need to specify additional program jars. 

In Bezug auf diesen Fehler gibt es eine Zeile in Ihrem Projekt, bei dem Sie Gießen/Behandlung eines Objekts als String und Proguard ist einfach nicht in der Lage zu sein damit umzugehen

[2016-07-29 13:16:13 - samAPPSampleAndroid] java.lang.ClassCastException: java.lang.Object cannot be cast to java.lang.String 

Überprüfen Sie Ihren Code für eine mögliche falsche Besetzung und damit umgehen.
