I am using the library and it works fine normally but when I applied the proguard to my project, the app is crashing with this error :

The xml integration is like this :

<com.github.glomadrian.grav.GravView
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:layout_centerInParent="true"
       app:animationGenerators="@array/BallWaveAnimations"
       app:array_colors="@array/bubble"
       app:ball_from_size="@dimen/dim_10"
       app:ball_to_size="@dimen/dim_20"
       app:colorGenerator="com.github.glomadrian.grav.generator.paint.ArrayColorGenerator"
       app:gravGenerator="com.github.glomadrian.grav.generator.grav.BallGenerator"
       app:pointGenerator="com.github.glomadrian.grav.generator.point.RegularPointGenerator"
       app:regular_cell_size="300"
       app:regular_variance="200"
       app:shake_direction="vertical"
       app:shake_max_duration="10000"
       app:shake_min_duration="10000"
       app:shake_variance="@dimen/dim_350"
       app:side_to_side_direction="downToUp"
       app:side_to_side_max_duration="20000"
       app:side_to_side_min_duration="10000" />

No changes are done in code about this xml view. Are there any pro guard rules which should be added ?

commented

alright so I fixed this issue by adding these lines to proguard :

-keep class com.github.glomadrian.** { ; }
-dontwarn com.github.glomadrian.*
-keepattributes Exceptions, Signature, InnerClasses

commented

Thanks @pramod7patel I just remove ";" from your first line and its working fine.
Add below lines of code in your proguard-rules.pro file if you are using com.github.glomadrian:Grav:1.+ library

-keep class com.github.glomadrian.** { }
-dontwarn com.github.glomadrian.*
-keepattributes Exceptions, Signature, InnerClasses
