My fingerprint button is also a return and exit button. When I press my fingerprint, the program will exit. What should I do?
Please show your blocks.
If blocks available, others may help you soon.
Upon clicking the button if it gets result you can set it to get return. If no result comes mean you can set it for exit
But actually, you can try to set different buttons
please show in English i cant understand
It means when fingerprint 1 on authentication succeeded, then
i did not asked that i know about that i wanna know the about the block inside it
The one inside is the display image, no problem
here you use if block,
If authedication success make button to go next screen, if not make the button to exit or say error
The block is for authentication succeeded so an if block wouldnât help here.
Liu does your fingerprint scanner trigger the âwhen screen back pressedâ?
The middle position below is the fingerprint touch key, which is also the touch key for program exit. As long as you touch it, the program will exit.

Well then thats the issue with your phone. If you meant
âYour phoneâs fingerprint sensor is on the back buttonâ right ?

Thank you for your help, very useful!
Answer is simple I think once the user done finger print verification ask activity starter to open app again with value opened again then when screen 1 initialize if start value = opened again using notifier ask do u want to exit if answer is yes exit application else continue
The issue @LIU is facing is when the user touches the fingerprint sensor the app closes because the fingerprint sensor is also the exit button
something like this the fingerprint sensor and the home button are the same
Yes I know thatâs why I said when finger print scanned use activity starter to open the same app so the closed one will open
