AndroidCameraPreview

Sample of camera preview application

—— [[ CAUTION ]] ———————————————————————————————————

This application is a template or a sample for processing camera preview images.

It is using android.hardware.camera API which deprecated since Android 5.0 Lollipop(API 21).

I tested on Android 8.0(API 26) and still running well , but you have to see Camera2 for production use.
