Follow below steps

• First you need to add proguard.cfg to your android project level.
• Change proguard.cfg file build action to ProguardConfiguration
• Change proguard.cfg file Encoding using Notepad++ to UTF-8

If you are getting warnings then you need to use -dontwarn attribute like below

-dontwarn com.symbol.emdk.**
-dontwarn org.apache.http.**
-dontwarn com.appdynamics.eumagent.runtime.**

You must need to remove/solve warning because that cause above error. Above code will remove all of your warnings.
If you are getting exception after executing your application you need to use -keep attribute. like below for required classes

-keep public class android.support.v7.widget.** { *; }
