Dependencies and prerequisites
- Android 1.6 (API Level 3) or higher
The Android system shows an on-screen keyboard—known as a
soft input method—when a text field in your UI receives focus.
To provide the best user experience, you can specify characteristics
about the type of input you expect (such as
whether it's a phone number or email address) and how the input method should behave (such as
whether it performs auto-correct for spelling mistakes).
In addition to the on-screen input methods, Android also supports hardware keyboards, so it's
important that your app optimize its user experience for interaction that might occur
through an attached keyboard.
These topics and more are discussed in the following lessons.

your layout should adjust to the reduced screen space.
- Supporting Keyboard Navigation

and how to make any necessary changes to the navigation order.
- Handling Keyboard Actions
