Hello,

I just purchased PA, and when I press on the track up/down button on my steering wheel, I hear a beep, but it doesn't change tracks.

 

when I view the "last commands"  I see it is recognizing I pressed the buttons but not sure why it isn't changing the tracks.... Any help would be great! Thanks!

Your device appears to be only sending KEYCODE ACTION_DOWN events (i.e. telling PA that a button has been pressed) but it does not seem to be correctly issuing a follow-up ACTION_UP event which tells PA that the button has been released, which allows the activity to be processed. As far as PA is concerned from this log, the button is being held down permanently.

ugh... That makes sense ..... any idea how to fix this (other than hoping the head unit manufacture will issue a fix)?

could you make an option to trigger just on the  ACTION_DOWN command?

[andrewilley]

I would have thought it would be technically possible for Max to create a PA option which overrides correct button behaviour and treats ACTION_DOWN on its own as the trigger for an action, but it would need to be enabled with caution as that setting would break any long-press options that a device might support.

The proper answer is for the manufacturers of the device to correct their firmware of course, but for a pre-installed car headunit that might be an uphill battle.

yeah, I just sent a email to the manufacturer  .. I give it a 5% chance they will fix it.   I hope PA will add this option, I really like the look of this player!!

 

I only know python, so I don't think I can figure out how to modify the firmware

 

Thanks!

I just noticed there is an API....  do you think this is something I "could" implement with the API?    Basically I just need to have the UP command triggered whenever it detects a DOWN command....

 

Like I said I never have developed for Android, but I'm not shy about learning

I know there are apps out there that can remap button functions, might be worth giving those a try first.
