I haven’t seen this issue, so just taking a wild guess at what the issue might be: How aggressive are your proguard optimizations? Do you have it set to do inlining? My guess is that the error looks like it’s coming from the proguard step of your build? If that’s the case you might be able to fix the problem by backing off the inlining or other optimizations proguard can do and stick to trimming the unused methods.
