Pick Image from Camera or Gallery -Android

 in this tutorial I will be showing how to get an Image from the user's Camera or from his gallery.

In this Tutorial User will have two choices:

Capture photo/ image from camera in Android

Choose photo/ image from gallery in Android

User will need to choose one option from the above two options and then depending on the option chosen by the user, we will either capture an image from the camera or open the gallery.
