Andre12

where can i add that???i found that to shut the Display on and off with a GPIO Pin i'm not real in programming and so on

#Prellzeit in Sekunden
KEY_BOUNCE_TIME=2

GPIO-Pin des Tasters

PinButton=14

GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
GPIO.setup(PinButton,GPIO.IN)

DisplayOn=True
while True:
time.sleep(0.1)
print(GPIO.input(PinButton))

if GPIO.input(PinButton)==0:
    #Taste wird gedrückt, wg. Pull-Up Widerstand beim Wert 0
    DisplayOn=not DisplayOn
    if DisplayOn==True:
        print("Bildschirm EIN")
    else:
        print("Bildschirm AUS")

    #Prelldauer für Taster warten
    time.sleep(KEY_BOUNCE_TIME)   

GPIO.cleanup()
sys.exit()

That looks like a Python script to me. Not sure whether Android will support that out-of-the box. Probably not.

The easiest way would be creating a shell script with the same functionality and starting it at boot time.
