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

Android viewpager with Circle indicator

ViewPager in Android allows the user to flip left and right through pages of data. In our android ViewPager application we’ll implement a ViewPager that swipes through three views with different images and texts.

Android ViewPager widget is found in the support library and it allows the user to swipe left or right to see an entirely new screen.

Today we’re implementing a ViewPager by using Views and PagerAdapter.
