Using the Android Device‘s Back Button
To make your application handle when users press the Back button on their Android device, add an event handler to your form for OnKeyUp, and use the following code within your event handler:
Delphi:
if Key = vkHardwareBack then
begin
// Do whatever you want to do here
Key := 0; // Set Key = 0 if you want to prevent the default action
end;
C++:
if (Key == vkHardwareBack) {
// Do whatever you want here
Key = 0; // Set Key = 0 if you want to prevent the default action
}
