BoostMultiDex
Load multiple dex files on low Android version devices
BoostMultiDex is a specialized Android-library created by ByteDance to address a long-standing performance and user-experience problem on older Android devices (specifically Android 4.x and below, i.e. SDK < 21), where loading multiple dex files after installation or upgrade can lead to extremely long “black-screen” freeze times during first startup. 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. ...
