I am literally new to the whole app-building, I've build website long time ago, but I've found the app-building a completely different game.
What I wanted to make is a very simple app, that would open (or open through) a few documents, pre-installed in the app.
They would be excel and pdf files, they don't necessarily have to be opened in the app, but at least open the correct program to read (pdf) or work on a excel document (WPS).
But, I've been reading all through the forum and yet can not get the app to work. I did manage to make more screens, one of them contains a webviewer for a webbased program and that works.
There is no native method for reading Excel files in App Inventor, they may be readable if you use the activity starter and open them in online Excel or Android Excel
Also, please refrain from using too many Button#.Click events; use a single Any Button.Click event, especially if you have a lot of redundancies in your logic.
There are some tutorials that will help you learn to code Erik
Here are some resources to help you learn to use the AI2 tools. A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
