Please help and Thanks in Advance.
I think you are using wrong proguard. This type of problem comes when something wrong with progurad. Try to replace your project.properties with this code- here is link - Progurad Code
Hope this will help you.
add this code to proguard.txt
if you are using v4
# support-v4
-dontwarn android.support.v4.**
-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-keep class android.support.v4.** { *; }
if you are using v7
# support-v7
-dontwarn android.support.v7.**
-keep class android.support.v7.internal.** { *; }
-keep interface android.support.v7.internal.** { *; }
-keep class android.support.v7.** { *; }
