MM Viewer API for Android - Read Objective-C++ Sources

A file with the .mm extension holds Objective-C++ source code: a mix of Objective-C and C++ that Apple’s toolchain compiles in iOS and macOS projects. The extension tells the compiler to accept both languages in one file, and such files appear in most large Apple codebases.

Cross-platform teams encounter these files frequently from the Android side, during code reviews, architecture discussions, or when a shared C++ core has Objective-C++ bindings. GroupDocs.Viewer Cloud renders an MM file as HTML, PDF or PNG through a REST call, so a review app or an internal tool on Android can present the source as tidy, readable pages instead of raw text.

A Gradle or Maven dependency brings the Android SDK for Java into the build, and the integration stays short; its samples show rendering, page selection and thumbnails. Because more than 180 formats go through the API, one viewer also displays the C++, Java and Markdown files stored alongside it.

Individual files display in the free online GroupDocs.Viewer app, and no setup is needed. The interactive API Explorer answers live calls during design work, and a free trial follows for the first build.
