Checking Application Layout
For the best possible user experience, you should optimize the layout and UI for the screen sizes of the target devices. Carefully consider what is the appropriate amount of content to present on the application UI for a mobile phone, tablet, or any other target device.
Relate the position and size of components to the dimensions of the display. This enables the same set of information to be presented on the screen in all resolutions; higher resolution devices just display finer graphics.
Change the settings in the Model view to check application layout.
Changing Device Models
The characteristics of your target devices, such as screen size and orientation, touch support, and the availability of a keyboard or home screen, affect application design.
The Device field displays the device type that is being emulated.
Device manufacturers and application stores might have their own usability criteria for applications.
Rotation changes the orientation of the primary display between portrait and landscape. Rotation is effected by a sensor.
By default, all applications can present in portrait or landscape orientation. Based on the product, one orientation is considered dominant. If the target devices require that applications support both orientations, ensure that your application layout is properly usable in them.
Applications can auto-rotate the screen according to the current device orientation or lock the screen into a particular orientation. The UI orientation field displays the supported orientations for the device model. Click the rotation buttons to change the orientation of the emulated device.
