All of these Android GUI templates, kits and stencils have all been designed to not only help you maintain the Android Design Guidelines but also to fast-track the initial prototyping stage of your app. All of the templates are fully editable and, depending on the template, are available in all popular formats (.psd, .ai, .eps, .png and Omnigraffle formats).
