Change Function of Play/Rewind/Forward Buttons

The buttons on the front of the phone (under the external screen), control Windows Media Player by default.
I'm sure many users don't like the fact that pressing the play/pause button (which happens accidentally) turns on windows Media player and its music.
My question is, is there anyway I can stop the buttons from activating windows media player when pushed, or better yet, is there a way to define what the buttons do (so I can use them to control another program) ?
Thanks for anyhelp.
I would like to bring this thread back form the dead. I would also like to know about this.. The phone keeps playing music while I have it in my pocket because of these damn little buttons.
Thanks
I had this problem too, 'till I told my StrTrk to lock the buttons when closing...
3125 external control of Conduits Pocket Player
I just found this solution to successfully hook into both the external buttons AND the SubDisplay using Pocket Player 3.2! Been looking for something like this for a while. I'm sure others will appreciate it as well.

[Q]Headphone button not working

Hi guys!
My current phone is a Thl W200 and it's got Jelly Bean 4.2.1 and I'm rooted.
My problem is with the headphone button which does not work. Before I had a Sony Xperia J and the headphones that I have used to work with it( the button, when pressed, did various commands such as play/pause/next etc.) but now the button does absolutely nothing when I play a media file.
I've run a few tests and I found out that my smartphone has CTIA standard (just like the Xperia J) and my headphones are compatible so there's no problem there. I also tried with a CTIA to OMTP cable to see if it works and nothing, the button doesn't control the music player.
One strange thing that I noticed is that if I get a phone call and I press the headphone button the call is answered, so it must work, somehow; Plus if I keep the button pressed the screen is locked and unlocked.
So my question is, if anyone knows, what can I do in order to use that little headphone button in order to control the music player?
P.S- I've also tried a few apps such as button controller, philips headset manager etc but they didn't work, the click was not registered.
Oh and another thing, I installed the key test app and when I pressed the headphone button the app didin't register any keys being pressed.
Can anyone help?
Thanks!

[Q] Power android tablet without power button

Hi
I'm trying to embed a generic Android tablet (4.4) into a console. Since it's physical power button is on its side and this area won't be accessible I need to find a different method to power on / off the device and provide the power button functionality from outside.
I initially thought about installing an outer button, disassemble the tablet, and solder the wires instead of the current button but there must be a different option.
The tablet has its usb socket. Is there a way to utilize that in order to connect a button through USB and using it?

[Q] Force/enable USB Audio on Jellybean?

I have a scanner that uses an Android tablet for it's interface, and has a USB port. The USB speakers I tried using on it however don't work. They light up to show there's power going to them, and the physical volume buttons on the speakers adjust volume (as in, the volume indicator appears on-screen). But no audio is heard through any app nor System Settings.
I'm wondering if there is a way to force/enable audio over USB? The scanner is rooted.

volume not working with S21 headphone

The Samsung Galaxy S21 got rid of the phone jack from previous models and now has only a USB-C connection. I bought a USB-C-to-phonejack converter so I could use the headphones I had from my S7 phone. It works when I am using the headphones to listen to music or watch videos. By "works" I mean not only do I hear sound through them, but I can control the volume either using the phones controls or the built-in controls on the headphones. EXCEPT! Except when on a phone call. When I use the headphones when using the phone, the volume control does nothing. Neither the controls on the phone itself, or the controls on the headphones. I end up deafened because the volume is at max and can't be turned down. Again, this is only while speaking on the phone; other apps let me use the volume controls.
Any ideas on ways to fix this?
Thank you,
S.

I can't guarantee that this will work. But often what seems obvious to me is something other people miss completely. (And the other way around too.)
When you press the volume down or up rocker on the phone, have you noticed the three horizontal dots at the top of the onscreen volume indicator? If you tap on that 3-dot menu, multiple vertical volume indicators appear. I haven't tested with a USB-C audio jack dongle but I am betting that if you have the dongle plugged in (regardless of whether the earphones are plugged into the dongle), one of those vertical volume sliders will be specifically for the dongle/USB-C output.
Give this a try and let us know if this works. If it does, I realize this might be annoying to do every time. But maybe then you can find a utility in the Play store that allows you to set individual volume levels.
Good luck.
P.S. I fully understand if you prefer the wired earphones. But I can tell you that when I use bluetooth earphones of various kinds, simply pressing the volume rocker does reduce/increase phone call volume.

Thank you. I never really noticed those dots in the volume control; just ignored them all this time! I pressed them and see the extra options. I haven't tried the USB-C dongle yet... I just packed it away for a trip this week. I'll keep it in mind though and try it as soon as I unpack.
