I already gone through some samples from Git hub but I couldn't make use of them.So, I decided to start learning Camera API from Google developers. Here I need a complete steps to develop my app and what to learn like camera, surface view and anything else.

Thanks in advance

Answer 1

I have done what you want to be done recently.

For android, there are 2 camera APIs

• the camera api

• and the camera2 api

camera api is deprecated on android api 21. starting from android api 21, you have to use camera2 api. so you have to learn both of them.

• Camera api brother with SurfaceView.
• Camera2 api brother with TextureView.

Camera2 api is quit alot different from Camera api, and also is much more complicated than Camera api.

You may want to take a look at my project SimpleCameraView , it is much clear than other projects. I just created this repository yesterday.
