At runtime, the device reports its configuration, and Android chooses the appropriate matching layout resources for that screen. Provide Multiple Layouts for Different ScreensĪnother way to provide an app that looks good on different screen types is to define multiple XML layout resources for different screen configurations. You can take advantage of the larger screen size by, for example, including more content or by making better use of portrait and landscape modes. In addition, when porting an app from a smaller screen to a larger one, consider redesigning your app's user interface altogether. See Use "wrap_content" and "match_parent" for more information.
Within your XML layout elements, do not specify width and height explicitly use the Android attribute values wrap_content and match_parent to dynamically size an element based on its content and its parent. See Use Constraint Layout for more information. Absolute layouts do not scale across different screens. Avoid AbsoluteLayout, which has been deprecated since Android 1.5 (API Level 3). Use the ConstraintLayout Android class to build your UI so that elements can be placed and sized relative to other elements. For more information, see Use Density-Independent Pixels. Also, use scale-independent pixels (sp) for text. The dp units have a baseline of 1 dp per pixel on a 160PPI (mdpi) device, but are automatically scaled at runtime for devices with higher screen densities. Create layouts by using density-independent pixels (dp) rather than absolute pixels. You can follow the Android best practices for designing an app for multiple different screen types, including: A flexible layout enables your app's user interface (UI) to dynamically scale to different screen sizes, densities, and aspect ratios at runtime. To address these issues, design your app to use a flexible layout. Text and images designed for a device with a specific screen density may have larger or smaller elements than you expect, which can affect both the appearance and behavior of your app. Text and images designed for a device with a specific aspect ratio may have distorted or overlapping screen elements on screens with different aspect ratios. Text and images designed for a device with a specific screen size may not properly scale to different screen sizes, or may look distorted or pixelated when scaled. If you design your app for a specific device's screen, it may both look and behave differently than you expect when it runs on a device with a different screen size, aspect ratio, or pixel density. Ensure that the icon provides a clear and identifiable image that positively represents your brand. Test your icon across the range of devices where you want your app to run. See Launcher Icon Guidelines for information about required icon resolution and dimensions. This is a change from earlier versions of Fire OS, where the launcher used the app icon that you uploaded to the developer portal when submitting your app. Understand How Fullscreen Modes Affect Layoutįor increased commonality with Android, the launcher on Fire OS 5 and Fire OS 6 displays the app icon that you provide within your APK.

This document provides an overview of options and techniques for managing different Fire tablet screens in your app. As an app developer, it can be challenging to create an app that runs and looks good on many different form factors, especially if you are porting your app from another tablet or from a phone. #Kindle is not optimized for your mac install#
