vibrator on android 10 java.lang.SecurityException

[skorpions2000]

I tested:

from plyer import vibrator
        try:
            print(vibrator.exists())
            vibrator.vibrate(1)
        except Exception as ex:
            print(ex)

in return on log my phone I have:

 I python  : True
 I python  : JVM exception occurred: Requires VIBRATE permission java.lang.SecurityException

Sorry,
Where is my mistake?

I'm write in buildozer.spec

# (list) Permissions
android.permissions = VIBRATE

It's working.
