Add reference to CMake project in Android Studio

Issue

In my particular case, I implemented a cross platform project in C++11 that uses CMake. I initially designed this project to work on PC (Windows, Unix), but now I realized that I can use it on mobile platforms too, without re-implementing the business logic on every platform. The project uses standard libraries: Boost, Poco, OpenSSL, Protobuf.

After a few searches I came to conclusion that this is not even an usual mode to put together native and managed code in Android.

1. Is it possible to add reference in a Gradle project in Android Studio to a native project that uses CMake?

2. Can NDK adopt the project in a simple manner if I compile everything in command line (assuming I don't use Android Studio)?

3. If it is possible, is it recommended at all?

Solution

Is it possible to add reference in a Gradle project in Android Studio to a native project that uses CMake?

Since Google announced Android Studio 2.2 that comes with cmake plugin, so it's possible to reference CMake project to android project.

Can NDK adopt the project in a simple manner if I compile everything in command line (assuming I don't use Android Studio)?

In my experience, i compile NDK in separate way and then link the static/shared library (.so file) to be used in android project. I used NDK while developing PDF Reader using mupdf here

Hope this helps.
