Its been a long while since I worked on a Unix system, so prefer not to risk my computer not working by trying to load another OS, if I can't get this working I may have to buy another machine - probably go for i5-7400 for more speed and full emulation with Windows 10. I also have a more modern Asus tablet, this does not have Developer mode in Settings, SDT also can't see this, but windows explorer can.

Refer below images if you are unable to get the above steps.LV426: good idea, just tried that, I have an old Sony phone which has Developer mode in the settings app, just switched it on but SDT tells me that 'No USB devices or running emulators detected' I can see the phone with windows explorer. Now create another empty activity by right click on app -> New -> Activity -> Empty Activity and rename the activity with Activity2 and also rename the layout name as layout_activity_2. Note: To rename the file click on the MainActivity -> Right-click -> Refactor -> Rename and similarly do for acticity_main file. Rename the MainActivity file as Activity1 and acticity_main as layout_activity_1 (renaming is done to avoid confusion between two activities). Note that select Java as the programming language.
