Android Splash Screen

  1. Draw the splash screen in gimp. For example, create a 1280 pixel x 720 pixel image with a pixel density of 240 ppi x 240 ppi (pixels per inch).

  2. Use the tool /Android/Sdk/tools/draw9patch which is part of Android SDK to mark regions which can be stretched. The overall image is 1282 x 722 pixels. Watch this video to see how to use the tool.

  3. Copy this image to /res/screen/android folder.
