The Esri ArcGIS Runtime Android Java Sample Code by Esri provides demonstrations for deploying the ArcGIS Runtime SDK in Android applications. Its deployment requires Android studio and the onward of JDK 7. The sample code communicates with Esri arcGIS APIs. Its Gradle-based Android platform allows developers to clone directly and import applications in Android studio.
Gravity, focused on personalizing the internet, has launched a new series of free APIs to further its mission. The APIs enable web publishers to recommend content to users in addition to sponsored stories from paying advertisers. Prior to the API offering, Gravity tools provided recommendations based on demographic and interests through widgets and home page personalization. The API should expand Gravity's reach into mobile apps and deeper web adoption.
Given the increasing popularity of mobile devices such as the iPhone and Android devices (both of which include full browsers), it should come as no surprise that developers have begun to leverage the various APIs out there to provide mobile mashups that can be implemented without targeting a specific platform or SDK.
