PayPal Android SDK With Multiple In-App Payment


PayPal announced a new Android SDK that tries to make it easier for developers to accept in-app payments on Google’s mobile platform.
As expected, the Android payments solution accepts both PayPal and credit card payments. The company says it is quick and easy to use, and “removes payment friction so developers can focus on creating amazing experiences.”

PayPal’s strategy is to make it as easy as possible for mobile developers to integrate its payments into their work. The pitch is simple: if consumers don’t have to leave your app to pay, and they can do so in more ways than one (click a PayPal button or scan a credit/debit card), they will be more likely to do so.

The new PayPal Android SDK supports Android version 2.2 and up. The new Android payment solution will allow developers to accept payments via PayPal and via credit cards. PayPal believes that giving users the option to pay quickly and easily via their PayPal account or by scanning a credit card will lure more customers into paying developers for their work.

PayPal says that it is also offering security features that will allow developers to “significantly reduce” fraud they encounter with payments. So I think that its really amazing concept for android developer.

Get the address using current latitude and longitude Today I am sharing the code of getting the current address from the current latitude and longitude. For implementing this concept we need to use the Geocoder. So here question is arises what is Geocoder? Geocoder is a class for handling geocoding and reverse geocoding. Geocoding is the process of transforming a street address or other description of a location into a (latitude, longitude) coordinate. Reverse geocoding is the process of transforming a (latitude, longitude) coordinate into a (partial) address.  The amount of detail in a reverse geocoded location description may vary, for example one might contain the full street address of the closest building, while another might contain only a city name and postal code. The Geocoder class requires a backend service that is not included in the core android framework. The Geocoder query methods will return an empty list if there no backend service in the platform. Use the isP...

Multiple Row Item Deleted from Listview Android In this article we are learning the new android API concept that delete the multiple  row item of the list view. Before we have knowledge about the delete the row item with the help of check box. But in new API-18 have provide the features to delete the multiple row item from the list-view without the check-box uses. This feature is available inside the contextual action mode in higher android version 3.0. So here question is what is contextual action mode? The contextual action mode is a system implementation of  ActionMode  that focuses user interaction toward performing contextual actions. When a user enables this mode by selecting an item, a  contextual action bar  appears at the top of the screen to present actions the user can perform on the currently selected item(s). While this mode is enabled, the user can select multiple items (if you allow it), deselect items, and continue to navigate within th...
