The Google I/O developer event got one more interesting announcement which is related to mobile payment. Today Paypal has announced library for Android applications which makes it very easy for developers to integrate Paypal payments.
Developers will simply need to download and integrate the library provided by Paypal. Library can be downloaded from developer website of Payal
Sample Pizza application built using Eclipse demonstrate how to do actual integration which is fairly easy. Although paypal seems forgot to use relative path for library. So you will have to change path library path and application is ready to go.
