2 ways

Backend or via SDK

Using PayPal

Android SDK

Sample App:

•  Sell a football jersey •  Fast Checkout •  Nice Interface

Present the product & allow to purchase it

Android SDK

Allow to pay via PayPal or Card

Android SDK

The user enters his credentials:

•  Email •  Password

Android SDK

The user needs to confirm his payment...

Android SDK

... and will be presented a confirmation of his purchase afterwards.

Android SDK

That’s nice... BUT:

What if the user doesn’t want to use PayPal or doesn’t have an account?

Accept credit cards in your application manually or...

Android SDK

... via image recognition technology in your app!

How-to

Your Activity: Stop your service in the lifecycle’s onDestroy( ) method to make sure it ends nicely and doesn’t use unneeded resources.
