核心特点

• •Efficient. MMKV uses mmap to keep memory synced with files, and protobuf to encode/decode values, making the most of Android to achieve the best performance.
• •Multi-Process concurrency: MMKV supports concurrent read-read and read-write access between processes.
• •Easy-to-use. You can use MMKV as you go. All changes are saved immediately, no sync, no apply calls needed.
• •A handful of files: MMKV contains process locks, encode/decode helpers and mmap logics, and nothing more. It's really tidy.
• •About 50K in binary size: MMKV adds about 50K per architecture on App size, and much less when zipped (APK).
