LiveCode Forums.

Hello all you here.I am from Serbia and I would like to build a app that will help students at math, but it is in Serbian(my native lang).
So I have materials:
Like this:

And I want to build a Android application.
From start page when you open will be main categories, then when you click some category you will have sub-category, and when you click sub-category you will have PDFs:

Now my question is that from what to start.Do you have some guide how to make this buttons and program them, when you click on them to automatically get you on that and that sub-category.
And is better that, to load PDF from website(on exp. dropbox) or to use it locally.I have arround 50mb of PDF which I would like to integrate.And how to program that.Do someone have some examples of code to capture how this thing work.I have some medium experience with PHP and MySQL.

Thanks in advance to all you.

Hi Sert3e,
Welcome to the forum!

First let me say that you can do this in liveCode but you will need a pdf reader on the Android device to actually read the pdf. You cannot open a pdf "IN" liveCode but you can open a pdf "WITH" liveCode.
In the Dictionary look up "files" and "folders", sticking the results from those into a list field will allow you to click on a name and open a folder/launch a file.
Tip: for mobile it's "launch url..."
