<p>Each of the documents in this section describe the usage, format and syntax for a certain type
of application resource that you can provide in your resources directory ({@code res/}).</p>

<p>Here's a brief summary of each resource type:</p>

<h2>{@code R.id} Is Not a Resource</h2>

<p>You will often use an {@code R.id} integer to handle {@link android.view.View} objects in
your UI. Although the {@code id} is a subclass of the {@code R} class, it is not considered a
"resource" because it is not a reference to an externalized application resource. The {@code id}
is simply a unique identifier that allows you to handle elements in your UI by instantiating
objects with {@link android.app.Activity#findViewById(int) findViewById()}.</p>

<p>For information about using {@code R.id} with your UI, see <a
href="{@docRoot}guide/topics/ui/declaring-layout.html#attributes">Declaring Layout</a>.</p>
