Fire tablets have a common user interface. However, the device specifications vary by tablet, so the pixel dimensions of the user experience elements also vary.
The following table shows the resolution for elements of the user interface in Fire OS 5, in device-independent pixels (dp). Note that the following screen elements are changing or are not included in Fire OS 5:
- Carousel app icons are not included.
- The Library Grid view is not included.
- Favorite app icons are replaced by the standard app grid icons.
|Status bar height (top)||24dp|
|Soft key bar height (when toolbar is visible)||48dp|
|Library list app icons||56dp x 56dp|
|Notifications app icon||24dp x 24dp|
|App icon||72dp x 72dp|
All Fire tablets support two-finger touch gestures. Except for Kindle Fire (1st Generation/2011) and Kindle Fire (2nd Generation/2012), Fire tablets detect 5 or 10 simultaneous points of touch and recognize two-finger touch gestures as supported on Android Ice Cream Sandwich (ICS) and later. Your app can take advantage of the multi-touch capability and optionally implement custom touch gestures that use more than two fingers. See the device specifications for the number of touch-points per tablet.
On any Fire tablet, the user interface for your app needs to respond to the following gesture patterns.
|Gesture pattern||Chrome||Standard application||Media||Maps||Images|
|Single-tap||Invoke action||Invoke action||Hide/show chrome||Invoke action||Invoke action|
|Press-and-hold||Context menu (in text field)||Text select, context menu||none||Location flag||Context menu|
|Swipe/Fling (horizontal)||Show/hide chrome||Scroll||none||Scroll||Scroll (photo or thumbnails)|
|Swipe/Fling (vertical)||Show/hide chrome||Scroll||none||Scroll||Scroll|
|Drag||Drag and drop||Pan||none||Pan||Pan|
