AndroidViews - Custom Android UI Views. Android SDK Development & Programming. This example explains how we can convert latitude longitude values to corresponding address.
The process is called Reverse geocoding. Algorithm: 1.) Create a new project by File-> New -> Android Project name it Gecoding-example. 2.) You will see some default code into your main.xml and android manifest file. 3.) 4.) 5.) 6.) Package com.example.geocoding; import org.xml.sax.Attributes; import org.xml.sax.SAXException; import org.xml.sax.helpers.DefaultHandler; public class GoogleReverseGeocodeXmlHandler extends DefaultHandler { private boolean inLocalityName = false; private boolean finished = false; private StringBuilder builder; private String localityName; public String getLocalityName() { return this.localityName; } @Override public void characters(char[] ch, int start, int length) throws SAXException { super.characters(ch, start, length); if (this.inLocalityName && !
7.) Steps: 1.) Build Target: Android 2.1 (Google API) Application Name: Gecoding-example Package Name: com.example. Application Fundamentals. Android apps are written in the Java programming language.
The Android SDK tools compile your code—along with any data and resource files—into an APK: an Android package, which is an archive file with an .apk suffix. One APK file contains all the contents of an Android app and is the file that Android-powered devices use to install the app. Once installed on a device, each Android app lives in its own security sandbox: The Android operating system is a multi-user Linux system in which each app is a different user. By default, the system assigns each app a unique Linux user ID (the ID is used only by the system and is unknown to the app).
In this way, the Android system implements the principle of least privilege. However, there are ways for an app to share data with other apps and for an app to access system services: It's possible to arrange for two apps to share the same Linux user ID, in which case they are able to access each other's files. App Components Activities Services <? Activities. Add reference library google-play-services.jar to project using MapFragment and SupportMapFragment.
To use MapFragment or SupportMapFragment on your Android App, you have to add reference library google-play-services.jar to your project.
Otherwise, ClassNotFoundException will be thrown caused by com.google.android.gms.maps.MapFragment or com.google.android.gms.maps.SupportMapFragment. To add reference library google-play-services.jar: - Right click on your project, select Properties. - Select Android on the left selection, scroll down to the Library at right, and click Add. - Select google-play-services_lib and click OK. - Apply and click OK. The series: A simple example using Google Maps Android API v2, step by step. Remark: Somebody report that ClassNotFOundException still happen even added reference library google-play-services.jar!

Android SDK: Working with Google Maps – Application Setup. The Google Maps API for Android provides developers with the means to create apps with localization functionality.
Version 2 of the Maps API was released at the end of 2012 and it introduced a range of new features including 3D, improved caching, and vector tiles. In this tutorial series, we will create an app that uses Google Maps for Android V2 in conjunction with the Google Places API. The app will present a map to the user, mark their current location and nearby places of interest, and will update when the user moves. This tutorial series about Using Google Maps and Google Places in Android apps will be presented in four parts: The processes required to integrate Google Maps and Google Places with Android apps are relatively complex and not suitable for beginners, so for the purposes of this tutorial it is assumed that readers have already completed at least a few basic apps in Eclipse.
This is a snapshot of the final app:
