take a picture with android ndk - camera api

Question

Is there a standarized API for taking pictures using Android NDK?

Or is it really necessary to go through Java for that?

Answer 1

1) There was an access to Camera.h in older releases like Froyo, 2.3.3.

Now, I see a Camera.h in KitKat, 4.4.4. It changed completely.

This is an unofficial API, so it's subject to change. Be ready to code and deploy different versions for different Android releases.

2) There is a Camera component in OpenMAX. People managed to create an OpenMAX recorder for Raspbery Pi. I yet have to find a working solution for Android.

These two questions are unanswered:

• OpenMAX recorder on Android
• Access camera via OpenMAX in Android

and I'm going to try OpenMAX.

3) We ran into an Android device where video4linux2 works (one can access /dev/video0).
