Developing for Android | Scala IDE for Eclipse Space
At the time of writing, the following facts hold true: Android applications are self-contained, there appears to be no way for users to deploy a shared library to a device The scala library therefore needs to be embedded in every android application that uses it The Scala nature can be successfully added to an ADT project Using ProGuard is *highly* desirable, to keep these apps to a manageable size There is no usable 1 eclipse builder for proguard that we can add to a hybrid Scala/ADT project Using the Android SDK to create an ant-based project from the command line yields the exact same project layout as using the eclipse plugin 1 Obfuscate4e and a couple of JavaME toolkits add ProGuard support, but not in a way that's suitable for our needs.
Obtaining User Location
Knowing where the user is allows your application to be smarter and deliver better information to the user. When developing a location-aware application for Android, you can utilize GPS and Android's Network Location Provider to acquire the user location. Although GPS is most accurate, it only works outdoors, it quickly consumes battery power, and doesn't return the location as quickly as users want.What is GPX? GPX (the GPS Exchange Format) is a light-weight XML data format for the interchange of GPS data (waypoints, routes, and tracks) between applications and Web services on the Internet. Current Status

GPX 1.1 Schema Documentation
This Manual is Outdated! This document applies to GPX 1.0. GPX 1.1 is the current GPX implementation . Introduction GPX (the GPS eXchange Format) is a light-weight XML data format for the interchange of GPS data (waypoints, routes, and tracks) between applications and web services on the Internet.
GPX 1.0 Developer's Manual
From Processing This page presents a Processing library to help you read and manipulate GPS data in the GPX format . Only basic information (latitude, longitude, elevation and time) is parsed but this should cover most uses; you will need to adjust the library if you need to support GPX extensions. A GPX file is an XML file with a collection of GPS Tracks inside. Each GPS Track has a name, and is a collection of GPS Track Segments. Each segment is a collection of GPS Points with latitude and longitude as well as an elevation and timestamp.

GPS eXchange Format
GPX , or GPS eXchange Format is an XML schema designed as a common GPS data format for software applications. It can be used to describe waypoints , tracks , and routes. The format is open and can be used without the need to pay license fees. Its tags store location, elevation, and time and can in this way be used to interchange data between GPS devices and software packages. Such computer programs allow users, for example, to view their tracks, project their tracks on satellite images or other maps, annotate maps, and tag photographs with the geolocation in the Exif metadata.
Thinking back, it's hard to believe that with so many Android phones on the market today, that the first version of the Android OS was released only 3 years ago, but the full story starts a few years earlier. It all began in October 2003 when Andy Rubin, Rich Miner, Nick Sears and Chris White founded Android Inc. in Palo Alto, California. Rubin was quoted by saying the purpose of Android was to allow "smarter mobile devices that are more aware of its owner's location and preferences", though at that time not much else was known about what type of phone software it would turn out to be.

Oracle this week showed JavaFX rich client software running on both an Apple iPad and an Android-based Samsung Galaxy tablet, along with introducing a separate project using HTML5 to bring Java to Apple's iOS platform, called Project Avatar. The company also cited intentions to converge its Java ME (Micro Edition) platform, which puts Java on mobile devices, with Java SE at the JavaOne conference. Oracle also said it was delaying until 2013 the release of Java SE 8, which had been due next year. Java has been barred from Apple's iOS devices, thanks to Apple's official policy not allowing third party technologies, such as Flash Player or Java, on the units. But a brief demonstration showed a JavaFX game running on an iPad.
