Only arm64, armv7a architectures are supported in this project. The hardened APK is provided for interested reverse engineers to analyze.
Updates: a. Re-aligned functions b. Fix scanning of executable sections only if it is readable to avoid crashes when app is targetting API 29 c. Stripped comment section in native library to prevent APKId detecting O-LLVM obfuscator is used
