Hey all

It is not possible to create a pdf file using the method described by Taifun in the post above with App Inventor without a connection to the Internet .

The 'solution' presented uses AI2 to communicate wiith a web page called www.convertapi   using the App Inventor Web component.

I am not aware of any way to create a pdf file within an Android device using App Inventor.   Here is a link describing how to create pdf's using a Java Android compiler:  http://stackoverflow.com/questions/2499960/how-to-create-pdfs-in-an-android-app  .   How one might do this on AI2 is not known.

Here is the Android documentation for one of the possibilities:  http://developer.android.com/reference/android/print/pdf/PrintedPdfDocument.html     Can it be used with AI2's ActivityStarter?  Probably not but you could try.
