2~~~~~~~~~~~~~~~~~~~~

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