Djinni is a tool that generates cross-language type declarations and interface bindings from an interface description language (IDL) file, primarily connecting C++ with Java (via JNI) and Objective-C. It was developed by Dropbox to enable cross-platform C++ library code to be used from Android and iOS apps.
Use cases
- generate Java and Objective-C bindings for a C++ library
- share C++ code between Android and iOS apps
- avoid hand-writing JNI boilerplate
- define data types once and generate C++, Java, and ObjC code
- call C++ code from Objective-C or Java transparently
When to choose
- you maintain a cross-platform C++ core used by Android and iOS apps
- you want a single IDL to generate bindings for C++, Java, and Objective-C
- you need bidirectional calls between C++ and Java/ObjC
When to avoid
- you need actively maintained tooling - the repo is no longer maintained by Dropbox
- you target languages beyond Java, Objective-C, or experimental Python
- you prefer modern alternatives like Djinni-derived forks or other FFI generators
