Android phone in car question?

[tequilagrae]

I would like to use an old android 2.2 phone I have, permanently installed in my car either as a speedo or as a tracking gps.
I can get it to open up a speedo app when the power is on and close the app when the power is off but I have to wake the phone up myself and swipe to unlock it.
I would like to get the phone to sleep when the power is off and wake up straight into an app when the ignition is turned on but it only goes to the lock screen.

Also I have an older android 2.1 phone that if I can get it to do the same I would like to use for a HUD.

Does anyone know how this can be done please?

If you root the phone, there are loads of apps and startup scripts that can do that sort of thing. Look on XDA-developers or google play store.

Thanks, I will have a look at XDA developers.
I tried loads of apps on the play store but I couldn't get one to do what I wanted.

Most advanced control apps need a rooted phone.

Edit. However, Tasker doesn't. It should do it I think. tasker.dinglisch.net
