The Android SDK offers a nice API to receive information about available providers for location based services and get the current location and coordinates. In this short tutorial we’re going to build a small activity that displays a list of available location providers and shows the current position using GPS services. Example Application Create a new Android Project using ADT and your IDE with a package named com.hascode.android.location_app Add the permissions needed to the AndroidManifest.xml – it should look like this <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.hascode.android.location_app" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".LocationActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="7" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission> <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"></uses-permission> <uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"></uses-permission> </manifest> ...

The integration of gestures into your android app adds some nice functionality and is made very easy using Google’s GestureBuilder application and the integrated GestureLibrary and Gesture Overlay API – so let’s build a sample app. If you need some basic information regarding gestures on android first – take a look at this article. Creating a gesture library First you need to define the gestures that should be captured in the application later. For this reason there’s the GestureBuilder delivered with the Android SDK. You can find the app in the samples directory of your android sdk – e.g. <installation-directory>/android-sdk-linux_86/platforms/android-2.1/samples/GestureBuilder. ...

With the Maven Android Plugin it is possible to build and deploy/undeploy your android app and start/stop the emulator – if you’re used to maven you won’t be going without it ;) If you’re interested in signing your apk using maven – take a look at this article Project Setup Create an android project using the android tool We need some dependencies – so create a pom.xml in the project’s root directory – I took this from the plugin samples and modified it: <?xml version="1.0" encoding="UTF-8"?> <!-- Copyright (C) 2009 Jayway AB Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
