BoostMultiDex
Load multiple dex files on low Android version devices
...Instead of relying on the standard Android MultiDex mechanism, BoostMultiDex reworks the loading strategy by tapping into hidden Dalvik VM internals so that original DEX bytecode can be loaded directly, bypassing costly ODEX generation. It adopts a multi-stage loading approach (DEX bytecode → DEX file → ODEX file) to pick the fastest viable route at runtime, and optionally performs optimization (OPT) in a separate process with interruption/recovery support — minimizing startup time and preserving stability.
