Example of interacting with the camera through native extensions
License: MIT License
Defold native extension which provides access to the camera on macOS, iOS and Android.
Manual, API and setup instructions is available on the official Defold site.
There's experimental Android support in the Android branch, but that branch uses the Java APIs. We should look into using code from the NDK example: https://github.com/googlesamples/android-ndk/blob/master/camera/texture-view/src/main/cpp/camera_manager.cpp
Even though the project doesn't support a platform it would be nice if it could still make them bundle/build successfully.
Sometimes a released version of the app can crash with the camera. I haven't found it crashing on a debug build so far.
