The short answer is the size of all layout elements in dip . dip abbreviated for Density-independent pixel , and Android automatically scales elements of the same dip size on different screens. (You can shorten dip to dp in XML layout files.)

The long answer is to read this article on the Android developer website . It's long, but I highly recommend reading it from beginning to end at least once before you go too far with your application.

There are several ways to achieve screen independence.

  • Use 9 patch images where possible.
  • Design scheme using units of measure like dp, sp and measurements (in, mm ... etc.).
  • Use fill_parent and wrap_content where possible.
  • Use a resource with qualifiers (specify resources for a group / device type)
  • Design, scale, and install using custom coding for your program (not recommended) Read the following:
