Android Project Structure in Eclipse and JAR Dependency
August 14, 2014
Android Project Structure in EclipseBefore start see the eclipse view of your project structure.
assetsassets directory is empty. We can keep our raw data in it like game data. When the project is compiled, all the files with its original name are also compiled in .apk file. In the application program, we can read these data using AssetManager. To navigate asset data, we can use typical URI.
binThis is the output directory of the android project build. Android project is archived as .apk. We can get apk file in bin directory.
genAndroid development tool (ADT) creates the classes in this directory. The classes are like R.java and BuilConfig.java.
libsAndroid application has private library dependency. Lib directory keeps those libraries. The jar can be like android-support-v4.jar.
resRes directory keeps resources of different types.
Android provides this directory to keep drawable bitmap or images or objects. Drawable object can have multiple states like normal, pressed or focused.
Android provides this directory to keep XML files that defines the screen layout.
This directory has XML files that defines the menu in application.
This directory keeps resource XML files. But these resource files are different from res directory files. The element types of these XML files are used to control how the resources are defined and they are placed into R class.
srcThis directory keeps our java classes like activity class.
AndroidManifest.xmlThis is the android manifest for our project. We define uses-sdk and application definitions.
project.propertiesThis files keeps the information like project target, android library reference etc.
