Stop reverse engineering and IP theft
Your business logic, algorithms and keys shouldn't sit in plain sight inside a decompiler. Appsolid packs and obfuscates your finished APK/AAB to make static analysis impractical — with no source-code changes.
How Appsolid protects it
In-memory DEX packing (AES-256-GCM)
Your original DEX is encrypted with a per-app AES-256-GCM key and loaded only in memory at runtime (InMemoryDexClassLoader). A decompiler sees the bootstrap loader stub — not your code.
Native O-MVLL obfuscation
Control-flow flattening, opaque predicates, MBA (arithmetic obfuscation) and indirect-call & string encryption applied to the native loader on 32- and 64-bit ARM, resisting automated deobfuscators.
String & code obfuscation
Opt-in string encryption plus arithmetic and control-flow obfuscation across your DEX — ART verifier-safe, with automatic fallback if verification fails.
Per-app keys & anti-fingerprinting
Each build is compiled with a distinct key scattered through the binary, and vendor/technique identifiers are stripped from the output — so cracking one app never extends to another.
Honest scope: Honest scope: protected code is decrypted in memory at runtime. Appsolid raises the cost of analysis dramatically and pairs with RASP (see “hooking & instrumentation”) to resist dynamic extraction. We don't claim “unhackable.”
