How To Create An Android App

December 20, 2011 admin Article

It seems as if there are a dozen Android apps appearing on the market every single day. One would have thought that a high level of skill was involved which would prevent such an influx of these apps but apparently not. We can thank Google’s App Inventor and similar creations for that. This application enables anyone with a computer, an Android phone and a little bit of developer knowledge to create an app. You begin at your browser where you can control how the app looks before setting its behavior. With a live connection between your computer and phone, the app manifests itself on your phone.

The first step towards creating an Android app is to install a Java Development Kit and Eclipse IDE for Java Developers. Once Eclipse is installed, start downloading Android SDK. Make sure you extract it to a safe directory. In Eclipse, you can add Android Development Tools by choosing ‘Help-Install New Software, Work With’ and enter the https:// code for Eclipse before hitting ‘Add-Development Tools-Next’. Android Development Tools and Android DDMS will be selected so now you just agree to the terms and conditions before restarting Eclipse. When Eclipse reopens, choose Windows-Preference-Android and click Browse before locating the folder which says SDK, applying and clicking OK.

Install a version of the Android platform and tick the components you wish to install while removing the rest. You must have the latest version of the Android platform if you wish to create an Android device. You’ll also need to test the app out on a number of different Android versions. Clear the USB driver, Google API’s and sample though you can use these later if need be. The next stage is to create an Android Virtual Device (AVD) which can be created in the SDK and AVD manager. When testing the app on different Android platforms, please note that a new AVD is required for each platform. A simple AVD can be created by simply accepting the default settings.

A new project can now be created and you can create the classic ‘Hello World’ app as a test by clicking ‘File-New-Project’ in Eclipse. When you find text, enter HelloAndroid in the Project Name line. You can experiment with this before clicking ‘Finish’. All these parameters are used to create an Eclipse project and you should see a number of subfolders on Windows Explorer. You can change the title of the app (which is shown on your Android phone) whenever you want. Once you have developed a published app, namespace is required.

You will then find a host of project fields that can be tampered with though you may be better served to leave them at their respective default settings. Once the app is completed, you will be forced to modify the code and this is where it can get tricky. Alternative Android apps can be created on AppsGeyser which simplifies the whole procedure and best of all, AppsGeyser is free to use. All you have to do when you’ve created an app is to upload it to the Android market and maybe you’ll make some money. If you’re really fortunate, you could have the next Angry Birds on your hands!
