Set Up REAL android development environment with MAVEN integration on Eclipse

Intro

Sometime ago, i built some easy android-app to read RSS feeds and post something on a provided url. Basically, i already knew how to build an android application using eclipse. But that just a start! Real android-apps-development, involving on several libraries and it takes hours to resolve required dependencies  without a tools to work on resolving those dependencies. Either you lost on finding the dependencies required or your apps getting too big when your apps ready to use. That's why MAVEN comes in hand.

Why MAVEN ?

Maven had the technology to split your application into several libraries and adding dependencies unto those libraries. That way, you won't be confused or lost in space when trying to note down your application dependencies. That's why maven should be REALLY considered when you building a large application. Well, what i mean large is an application which is more than hello world :-D

- Click OK
    1. On root of your project, right click and then choose New -> Other -> XML -> XML File
      Give your new XML File name : pom.xml
      Choose Template Name that you've defined earlier on step 1 (one)
    2. Modify your pom.xml file
      1. <parent> tag
         org.someapp.somename
          someapp-android-somename
          theAppVersion
        
        
        Change value on tag :

        - groupId : into application group id  (ex: org.mycompany.myapp)
        - artifactId : into application artifact id. (ex: myCompanyApp.myFirstApp)
        - version : Application Version (ex: 1.0.0)

                    android

                    provided
                
        
        If we want to add additional library such as spring-android library : just add the following  into this tag.

        
            org.springframework.android
            spring-android-rest-template
            ${spring-android-version}
        
        
    3. You are set and done just try to run mvn clean , mvn install, mvn android:deploy
