    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.

Classes must be easy to unit test and reason about in isolation. Individual RIB classes have distinct responsibilities like routing, business, view logic, creation. Plus, most RIB logic is decoupled from child RIB logic. This makes RIB classes easy to test and reason about independently. Tooling for developer productivity. RIBs come with IDE tooling around code generation, memory leak detection, static analysis and runtime integrations.

    Shadow

    Shadow

    Zero reflection fully dynamic Android plugin framework

    Shadow is an Android plug-in framework independently developed by Tencent, which has been tested by hundreds of millions of online users. Shadow not only shares the key code of plug-in technology with open source, but also completely shares all the designs required for online deployment. Reuse the source code of the independent installation App. The source code of the plug-in App can be installed and run normally. Zero reflection and no Hack implementation of plug-in technology. In theory, it has been determined that there is no need for compatible development of any system, and there is no hidden API call, which does not conflict with Google's strategy of restricting access to non-public SDK interfaces. It is difficult to implement a perfect plug-in framework at one time, but Shadow makes all these implementations dynamic so that the code of the plug-in framework becomes part of the plug-in.
