Looks like some problem with proguard.

-keepclassmembers public class com.mindorks.test.swipe.TinderCard {*;}
Added above line to build in minified mode

@mwshubham
Please add these lines in the proguard.

  -keepattributes *Annotation*
  -keepclassmembers class ** {
    @com.mindorks.placeholderview.annotations.** <methods>;
  }

[mwshubham]
