Accessing the camera in Android

To start with, we will create a simple camera activity to get to know the principles of camera access in Android. While there are convenient Android applications that provide quick means for snapping a picture or recording a video through Android intents, we will get our hands dirty and use the Android camera API to get a customized camera access for our first application.

We will guide you, step-by-step, in creating your first app showing a live camera preview. This will include:

  • Creating an Eclipse project

  • Requesting relevant permissions in the Android Manifest file

  • Creating SurfaceView to be able to capture the preview frames of the camera

  • Creating an activity that displays the camera preview frames

  • Setting camera parameters
