Android App Development

Android is one of many Operating system for Smartphone , Android Inc. was founded in Silicon Valley, California, in October 2003, with the idea of providing a mobile platform that is more aware of the user’s location and preferences.

Google acquired Android Inc. in August2005 as a wholly owned subsidiary of Google Inc. Google’s main intention was to provide a fully open platform, backed by Google technologies, for both the users and the application developers.

In November 2007, the Open Handset Alliance was founded as a consortium to develop an open standard for mobile devices. Open Handset Alliance began its journey by announcing the Android platform. In less than a year, new members started joining this consortium.

Why Android ?

Android is the first complete, open, and free mobile platform.

·         Complete : The Android platform is a robust, secure, easily upgradable, mobile platform with a comprehensive framework and well-defined interfaces. It allows application developers to develop and fully blend their applications into the platform. It also provides compatibility and certification programs, so device manufacturers can design highly compliant devices.

·         Open : The entire Android platform has been developed and provided under open source Apache licensing terms. Android does not distinguish between preloaded applications and third-party applications. Developers have full access to device features and services while developing applications.

·         Free : The Android platform does not charge any licensing, royalty, membership, or certification fees to develop applications on the platform. Android platform source code and software development kits are provided free of charge to application developers. The software development platform is widely available on many desktop operating systems, allowing application developers to develop applications using the operating system of their choice.

Now, Android is one of the majors player in market. And now android version is 4.2 (API 17) a.k.a Jelly Bean . Ok today, I will give a little tutorial to develop android app. There is some tools that you will need for start to develop android app, here :

·         Java (Click for download)

·         Android SDK bundle (include netbeans and emulator) (Click for download)

here we go, if you have install Java, Unzip your (android SDK bundle) then open Netbeans

Then click android SDK manager.

Check your SDK is ready or not. (the most important think is SDK platform & ARM EABI v7a System Image if both or them is installed that’s mean your android version is ready).

  

For our first project android click File > New > Android Application Project.

Then fill your application name, project name, package name (I choose org.mobilephone45.blogspot.com.helloworld) the mobilephone.45.blogspot.com you can change with your pleasure. The package name is your package for java codes. Choose minimum SDK (minimum android version to run your apps), Target SDK (your android version target to run this app), Compile with (your compiler), Theme (theme for your app).

Next step, choosing your launcher or activity, it mean if you want to create your own activity with your creativity you can uncheck create activity .

Choose your launcher icon, if you want to create your own, you can click Browse in Image File

Choose your activity, if you uncheck Create activity before, you won’t need this but if u check create activity you’ll need this.

Click Next and Finish. (not Finish to develop an app I mean lol) this Finis is Finish to configure your app :) .

Then you will see this one

Just like that you can run your first app with Android Virtual Device Manager, if you not configure your AVDM yet, check this out.

Click Android Virtual Device Manager

Then New

 

Configure your AVD like this

(AVD Name can named with (space))

Then click OK, after you click Ok, click START.

After you click start, your AVD will open (maybe

Need a few time to wait your AVD load, be patient)

If you want to run your app, just Righ Click on your Package , Run As > Android application

HERE WE ARE, your first android app is finish.

Ok, maybe that’s a little bit about Android App Development, all you need is improve your self for become good developer. And sorry for my bad English :) .
