PayPal has just launched its Mobile Payments Library for Google’s Android OS, allowing developers to include in-app payments into their software. Thanks to this, when everything is set up right, you’ll be able to make PayPal transactions on your Android device without having to leave the application that you’re currently using. This would make life a lot easier for many folks, as you can see from the picture above; purchasing a pizza using PayPal on your Android device is possible. Of course, some folks are wondering whether this in-app PayPal payment method violates the Android Market Content Policy for Developers, as it states that “developers should only charge for applications and downloads from Android Market through the Market’s Payment Processor”. Will there be an argument between Google and PayPal over this?
