I'm already fix this issue by

on /android/app/build.gradle please make sure about this setting

 proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro", 'dexguard-release.pro'

and on rule file add -keepresourcefiles lib/**

at first, I can not use keepresourcefiles because my proguardFiles getDefaultProguardFile wrong (I was adding dexguard-protected.pro because I thought I have to add it too)
