What is the most feasible image format that I have to use with android devices. (Keep compatibility issues in mind) ?

Options
1) .jpg or .jpeg
2) .png
3) .gif
4) .9.png

• 4) .9.png
  .9.png patch image is the suggestible image to use,Because it has the capability of scrolling and padding automatically based on the screen size
