nmmp is an APK/AAB/AAR hardening tool that converts Dalvik bytecode from classes.dex into native C code executed by a custom dex virtual machine, making decompilation significantly harder. It consists of nmm-protect (a Java tool that transforms dex data into C structs with randomized opcodes and generates an NDK project) and nmmvm (the C-based dex-vm interpreter).

Use cases

• protect android apk from decompilation
• convert dex bytecode to native code
• harden android app against reverse engineering
• obfuscate classes.dex with a custom virtual machine
• protect aab and aar artifacts
• randomize dalvik opcodes to break decompilers

When to choose

• you need to protect selected Java/Kotlin methods in an Android app from static analysis
• you want an open-source dex-to-native protection without commercial packers
• you need to harden apk, aab, or aar builds via a command-line pipeline

When to avoid

• you only need name obfuscation - ProGuard/R8 is simpler
• you cannot ship native libraries or use the Android NDK
• you require a certified commercial-grade anti-tampering solution with support
