question

Hi Barry, First, note that the Fire Phone differs from the current Fire tablets in that it does NOT use a soft key bar. This is replaced in the Fire Phone with a dedicated ‘Home’ button and the EAC library, part of the Fire Phone SDK that allows you to take advantage of the devices Foundation Controls (HeaderNavigation bar, ToolBar, etc). https://developer.amazon.com/public/solutions/devices/fire-phone/overview/implementing-foundation-controls-for-fire-phone If you are trying to adapt a current Android app, and not use any of the features available for the Fire Phone, you can refer to the standard specs for a 1280 x 720 px (640 x 360 dp) / xhdpi device: Portrait Details Content View: 1134 x 720 px (567 x 360 dp) Landscape Details Content View: 590 x 1280 px (295 x 640 dp)

Hello, Thanks for your response. I'm glad to see the soft key bar is history. You mention a dedicated home button. I guess this implies that there is only one button at the bottom of the screen. How does the phone execute the standard android functions such as "Back" and "Menu". I followed your link and read about some of the SDK features. Unfortunately this really doesn't tell me much. A few images of an actual Fire screen, some of the features in action, some of the ways they are intended to be used, and how one performs standard Android functions would be very helpful. Many apps are full-screen with no-title. The Kindle tablets seem to like this mode for apps. In this mode how would a user perform the functions of the menu button press or back button press? Barry.

Hello, I found the Fire Phone App compatibility test and tried two different apps. I added the web addresses for two images showing the testing results (it doesn't seem like you can post images to this form). The first shows an app which is actually locked in landscape mode, however the test shows it in portrait mode. Notice on what should be the right hand side there is a black navigation bar, similar to what's found on the Kindle tablets. I assume it allows you to access the Android Menu and Back functions. From your previous post I assume that the width is 130 pixels. 1) android.canalrun.com\junk\csfiretst.png The second screenshot is from the testing results for an app that can be either landscape or portrait. Your testing shows portrait. Notice at the bottom there is no similar black bar to open the Android Menu and Back functions. I read in reviews that an upward swipe opens allows one to access to functions. This execution is again very similar to the Kindle tablets. 2) android.canalrun.com\junk\hmfiretst.png A couple of issues seem to immediately crop up. In landscape mode, is this black bar always present? Notice it covers the ad. This is a no-no. Also a swipe to pop up the black bar would cover the ad unless I reserved space for the pop-up in my app. Referring to the second screenshot in portrait mode, does an upward swipe open a black bar? This would also cover the ad unless I reserved space. It would be preferable to always have the black bar present otherwise it will appear as if there is blank space at the bottom of the app until someone happens to swipe. Is there a way to force the black bar to always be present in both portrait and landscape modes? Barry.

Hi Barry, The Fire Phone compatibility test captures a point in time for the screenshots, I agree it can be confusing, nothing beats the actual device. The black bar pops when the user swipes up, stays visible for 3 seconds and is then removed. In short, you would generally not account for this brief user interaction as part of your UX. The nav bar is designed to lay over whatever is on the screen for a short time, and only when the user requests it, it then disappears. The idea is to allow you to maximize screen real-estate and not have to take the nav bar into account for your UX.

Could you please let us know the following on Fire phone: 1. App Icon Size for Grid Display 2. App Icon Size for Carousel Display 3. In-app icon specifications (dimensions, colours, styles) Is there a developer style guide for app graphics? Many thanks in advance.
