1 Android Skeleton App 2 ~~~~~~~~~~~~~~~~~~~~ 3 4 5 This directory contains the full implementation of a basic application for 6 the Android platform, demonstrating the basic facilities that applications 7 will use. You can run the application either directly from the "test" 8 list in the app launcher (it is named Skeleton App) or by selecting it from 9 the top list in the Sample Code app. 10 11 The files contained here: 12 13 14 AndroidManifest.xml 15 16 This XML file describes to the Android platform what your application can do. 17 It is a required file, and is the mechanism you use to show your application 18 to the user (in the app launcher's list), handle data types, etc. 19 20 21 src/* 22 23 Under this directory is the Java source for for your application. 24 25 26 src/com/android/skeletonapp/SkeletonActivity.java 27 28 This is the implementation of the "activity" feature described in 29 AndroidManifest.xml. The path each class implementation is 30 {src/PACKAGE/CLASS.java}, where PACKAGE comes from the name in the <package> 31 tag and CLASS comes from the class in the <activity> tag. 32 33 34 res/* 35 36 Under this directory are the resources for your application. 37 38 39 res/layout/skeleton_activity.xml 40 41 The res/layout/ directory contains XML files describing user interface 42 view hierarchies. The skeleton_activity.xml file here is used by 43 SkeletonActivity.java to construct its UI. The base name of each file 44 (all text before a '.' character) is taken as the resource name; 45 it must be lower-case. 46 47 48 res/drawable/violet.png 49 50 The res/drawable/ directory contains images and other things that can be 51 drawn to the screen. These can be bitmaps (in .png or .jpeg format) or 52 special XML files describing more complex drawings. The violet.png file 53 here is used as the image to display in one of the views in 54 skeleton_activity.xml. Like layout files, the base name is used for the 55 resulting resource name. 56 57 58 res/values/colors.xml 59 res/values/strings.xml 60 res/values/styles.xml 61 62 These XML files describe additional resources included in the application. 63 They all use the same syntax; all of these resources could be defined in one 64 file, but we generally split them apart as shown here to keep things organized. 65 66
