Thank you for your post. I solved my problem.
I have an other question: Is it correct to insert additional libraries in ....|Anywhere Software\Basic4android\Libraries or should they placed anywhere else and how?
I am coding an app for an almost blind person (and for fun). Instead of doubleclick, longclicks etc. I found an other better solution: Using voice recognition for writing text, a catch self defined spoken commands and write code for these commands. This approch is very promising. Some commands have been accomplished.
B4A is a wonderfull tool. I am happy about it.
(I hope that my Englih is not too bad!)
