You can try to use MMAL - but there is nearly zero documentation on it.

Of course , the foundations camera apps might be useful as example code ...

What you are attempting is a difficult job, requiring quite a bit of Android experience. You can use the raspistill/vid apps as examples for the MMAL aide of things, but it's going to be a long job.

Just a warning....
