This app helps you, find different screen sizes for different layout development

Android runs on a variety of devices that have different screen sizes and pixel densities. The system performs basic scaling and resizing to adapt your user interface to different screens, but there is more work you should do to ensure your UI gracefully adapts for each type of screen.

Screen sizes

The screen size is the visible space provided for your app UI. The screen size as it's known to your app is not the actual size of the device screen—it takes into account the screen orientation, system decorations (such as the navigation bar), and window configuration changes (such as when the user enables multi-window mode).

Support different screen sizes

Android devices come in all shapes and sizes, so your app's layout needs to be flexible. That is, instead of defining your layout with rigid dimensions that assume a certain screen size and aspect ratio, your layout should gracefully respond to different screen sizes and orientations.

By supporting as many screens as possible, your app can be made available to the greatest number of users with different devices, using a single APK. Additionally, making your app flexible for different screen sizes ensures that your app can handle window configuration changes on the device, such as when the user enables multi-window mode.
