Designing Android applications using Pencil
Pencil provides stencils and templating options for including custom widgets, which are required for designing specific applications such as Android or iOS apps. A list of all available stencils and templates can be found at http://pencil.evolus.vn/StencilsTemplates.html.
In order to prototype an Android application using Pencil, download Android Stencils from http:// evoluspencil.googlecode.com/files/ Android.GUI_v2.zip.
Download the above Zip collection and import this collection using Tools > Install new collection > Select location of download.
This will import all widgets available in the collection, which can be accessed in the Collections toolbar.
You can also design and prototype iOS applications and Web applications using Pencil stencils and templates, as well as design your own widgets and package them as a collection.
Pencil can export designs in various formats such as SVG, PNG, PDF and even the ODT file format. It is an effective tool, which can save you money as it is free and open source. Also, developers become less dependent on designers. For more information on Pencil, you can visit http://pencil.evolus.vn.
