permissions for system features.</p>

<p>You can use some resources directly from these {@link android.R} classes in your own

applications, but you should generally use only resources that you've provided directly in your

application, in order to provide a cohesive application package that has no external dependencies.

In particular, you should not use drawable resources from the {@code android} package, because they

may change between platform versions, causing unforeseen conflicts with your design. Typically,

{@link android.R.style styles} are the only resources you should use directly from these

resources.</p>

<p>For information about using resources, see the <a
