I understand that you want to compile the App and install it in your phone or tablet, right?
if so the answer is yes.
After compiling the App, close the IDE and open the "Objects" folder.. you will see the compiled APP "xxx.apk"
(xxx is the name of your b4a project and also the apk). then connect your device in the computer and copy the apk
file in the downloads folder (or any other folder that you can remember). And finally disconnect your device from
the computer and open the apk from that folder in your device and follow the installation instructions.
I hope this is what you wanted and didn't waste your time.
