    I've created and published a simple app(USMC Knowledge), and right now I'm in the process of adding some more features. They should be simple to implement but I can't find any literature on how to learn to do these things. If anyone can provide a link to a site with instructions or help with coding that'd be great. Here's my agenda:

    Make an image that is displayed zoomable
    --I already am displaying the image in a LinearLayout with an ImageView inside and it works fine. But I can't find a way to make it zoomable, I've found a way to add the buttons but it's not functional.

    I would like to add a pdf file to the app, and make it zoomable/searchable.

    Finally I want to make a custom calculator. IE 3 designated inputs will give a single specific output.


    Any kind of information is GREATLY appreciated. I can't find anything on the web for any of this..

    1) Android one finger zoom tutorial ? Part 3 | Developer World

    2) What do you mean by "Add a PDF file"? Are you downloading one, creating one, what?

    3) a calculator is nothing but a collection of buttons performing multiple conditional operations. This one should be easy... tedious, but easy..
