Paypal-express Checkout Quick Payment method of Android development experience (ii)

First, leading

The previous article is not very good, here again to talk about.

PayPal mobile payment is available in 2 formats:

1.Mobile Express Checkout,mec, fast payment

2.MPL

If using the MEC payment method, this way click the Checkout button after the page until the end of payment is the form of the URL, you must first have a Web site payment , so can only be recorded through the form of WebView, use and web site effect, like, If some content in the loaded page does not want to be displayed, you can hide it.

Second, MEC payment case

The above example is what I actually used in the app, and I didn't find any problems. To do MEC payment, the main idea is to filter the URL, to display and Disappear dialog box, page hiding operations, such as the middle involved JS.
