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.

Share Via Option in Android

In this Application you will learn to implement an effective and user friendly share action to android app. You can add android share action anywhere in your application.

Here I have added share action in actionbar/toolbar and on button’s click event.

 If user clicks the share button from actionbar/toolbar,

many options will be available there to share like whatsapp,email, gmail, facebook, linkedin,twitter
