Hi. Nice initiative! Do you have any plans to have similar one for DexGuard customers?

Thanks,

Great question, @Roland_Yeghiazaryan. The -keep rules are compatible so this works for DexGuard rules as well as ProGuard (and also R8). However, we don’t have any immediate plans to support DexGuard specific rules.
