If you are looking for how to handle the hardware back button in your Delphi Android application then I think I have found the best answer to it on Stackoverflow. There are quite a few answers to the question multiple times but I think this one handles it the best. In addition to handling the back button it also takes the virtual keyboard into account and also handles a back button press when the virtual keyboard is visible. Here is a short snippet on how to just handle the back button but you’ll need to view the full answer to get the virtual keyboard part of it.
