![]() ![]() For automated tests, turn on accessibility checking in Espresso and Robolectric. Consider using Accessibility Scanner for Android for manual testing of your app on-device. Ensure that each of those elements is 48x48dp in size, or approximately 9mm in each dimension.Īndroid's automated testing tools can detect small touch targets.Identify all clickable, touchable, or interactable elements within the interface.To manually verify that an app's user interface doesn't contain small touch targets: The recommended target size for touchscreen objects is 7-10mm.įor examples, refer to the Material Design Accessibility guidelines. A touch target of 48x48dp results in a physical size of about 9mm, regardless of screen size. Loading partial data on demand reduces usage of network bandwidth and system resources. The Paging Library helps you load and display small chunks of data at a time. A circle will pop up showing the color I recommend Silhouette Studio. Paging 2 library overview Part of Android Jetpack.

To retain the original size of a View while expanding its touchable region, consider using a TouchDelegate, which allows a parent layout to handle touch events on behalf of the descendant View. If these controls are sized dynamically, or resize based on the size of their content, consider using android:minWidth and android:minHeight to set a lower bound on their dimensions. When implementing clickable or touchable elements in a layout, consider using dimensions that meet or exceed the recommended size for touch targets. Consider making sure these elements have a width and height of at least 48dp, as described in the Material Design Accessibility guidelines. Any on-screen element that someone can click, touch, or otherwise interact with should be large enough for reliable interaction. ![]()
