The best way to include images in android application package
<p>I'm developing an application for android, the application shows a list of activities of a carnival. I want that the application has the images of every activiy to avoid the user has to download it when runs the application, and improve user experience's with the application.</p>

<p>To do it I have added the images for every activity as resource, but I don't know if this is the best way to do It. There are some limitation with Resource that I don't like for example you can't create subfolders in drawable folder to organize the images, the only characters accept as a resource name are [a-zA-Z0-9_], and others....</p>

<p>Is there any good way to do it? or I have to use resources if I want to avoid the user has to download the images.</p>

<p>Thanks</p>
