Building Android on Mac

It is possible to init and build for Android on Mac?

It seems that when attempting to doing do, the init process pulls in linux specific files and when I try to build, it looks for linux specific build files.

I had to manually replace the android_ndk directory with darwin support files, since it only had linux, just to complete the init process.

Is there any way to configure all this for a Mac-based environment? Or, is Linux mandatory to init and build for Android?
