Android camera :

Most Android devices have at least one camera. Some devices have a front and a back facing camera.Using the camera on the Android device can be done via the integration of existing camera application.

 These are the following two ways , in which you can use camera in your application

1. Using existing android camera application in our application
2. Directly using Camera API provided by android in our application.

The basic:

The Android framework supports capturing images and video through

the camera  API or camera Intent. Here are the relevant classes.

Camera

This class is the primary API for controlling device cameras. This class is used to take pictures or videos when you are building a camera application.

Surface View




This class is used to present a live camera preview to the user.

Media Recorder




This class is used to record video from the camera.

Intent




An intent action type of MediaStore.ACTION_IMAGE_CAPTURE or MediaStore.ACTION_VIDEO_CAPTURE can be used to capture images or videos without directly using the Camera object.
