    MMKV for Android

    MMKV for Android

    An efficient, small mobile key-value storage framework

    MMKV for Android is an efficient, small mobile key-value storage framework developed by WeChat. Works on Android, iOS, macOS, Windows, and POSIX. Efficient. MMKV uses mmap to keep memory synced with file, and protobuf to encode/decode values, making the most of Android to achieve best performance. 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. MMKV contains process locks, encode/decode helpers and mmap logics and nothing more. It's really tidy. MMKV adds about 50K per architecture on App size, and much less when zipped (apk). MMKV is published under the BSD 3-Clause license. Starting from v1.2.8, MMKV has been migrated to Maven Central. Older versions (<= v1.2.7) are still available on JCenter.
