Android resizes the layout of the application immediately based on the sizes of different display screens in general. Sometimes when this programmed resizing does not take place, the consumer has got to manually establish the resolutions of the app based on the display screen dimensions. The end users are provided along with the selections such as small, normal, large plus xlarge for setting the resolution. Customer can easily select as an example, selection layout-normal for standard screen size.

Apps developed in these formats are not scaled by Android. That's why, it is at all times better to function with compatibility mode. Developers should better use nine-patch bitmaps, a PNG file especially put to use for elongating images and also XML defined drawables.
