/res folder and subdirectories
Description
Resource files are stored in various subdirectories based on their type
under /res folder.
Folder
Here are some important subdirectories in
the /res folder and the types of resources they host:
- anim: Compiled animation files
- drawable: Bitmaps
- layout: UI and view definitions
- values: Arrays, colors, dimensions, strings, and styles
- xml: Compiled arbitrary XML files
- raw: Noncompiled raw files
Note
The resource compiler in the Android Asset Packaging Tool (AAPT) compiles all the
resources except the raw resources and places them into the final .apk file.
apk stands for Android package.
This .apk file, which contains the Android application's code and resources,
correlates to Java's .jar file.
The .apk file is what gets installed onto the device.
Naming
XML resource parser allows resource names such as hello-string, but you
will see a compile-time error in R.java. You can fix this by renaming your resource
hello_string.
