Help with NoSuchMethodException

Hello everybody. I have had my app Pixel Studio in the store for a while now. However, I put out an update last week and my rating is tanking. I’m not really getting many crashes in my reports, but I am now starting to get a NoSuchMethodException. I have tested on several devices and am unable to cause a crash. From the stack trace, it is happening when the user presses the next or previous frame buttons, and saying that those methods that are called from onClick do not exist.

Has anybody experienced this before? I have checked everything. The methods are definitely there.

You can get Pixel Studio here,, if you would like to try it out.

Thanks for the help!

I just made a change in my proguard file to keep all of the methods in that class. Maybe that will work.
