| * Utility to support Action Bar like UI for all the devices. |
| * |
| * Android 3.0 (or later) supports a new UI named "Action Bar", and it is recommended to be used. |
| * However, Google Japanese Input supports also Android 2.3 or earlier. |
| * To provide quite similar user experiences for all the platforms, we implement "mimic" of |
| * Action Bar for such earlier devices. |
| * On the other hand, on later devices, we use Action Bar itself (supported by Android OS). |
| * |
| * This class provides utilities to fill the gaps between earlier and later devices. |
