i am trying to create a vibrating app, i need the phone to vibrate in the background with the screen locked.
the vibration has to be controlled by another cell phone.
For example: I want the cell phone to vibrate 3 times and stop and then vibrate 5 more times and stop, this command coming from another cell phone.
the play store Vibrava - Vibrator & Vibrator Tool app “https://play.google.com/store/apps/details?id=com.jgdevlabs.vibra&hl=pt_BR&gl=US” does look like what I want.
can you teach me to vibrate in the background? how much do you charge to help me?
