[BUG] Amethyst is always playing media when I enter my car and my phone connects to bluetooth

[ghost]

Describe the bug
My phone connects to my car via Bluetooth (not Android Auto - plain old Bluetooth). When I enter the car, my phone automatically connects to Bluetooth which automatically starts playing media from Amethyst, even though the app is not in active use.

To Reproduce
Steps to reproduce the behavior:

1. Connect your Android device to a car media system via Bluetooth
2. Leave the car/disconnect from the car Bluetooth
3. Open Amethyst, casually scroll your feed (making sure to scroll past some video content)
4. Put the Phone to sleep
5. Enter the car/connect to the car Bluetooth
6. Car media system is playing the audio from the last video that I viewed on my Amethyst feed

Expected behavior
Amethyst should ideally never be playing media through the car sound system, unless I explicitly open the app and watch a video with the app in the foreground.

Video and Screenshots

Device (please complete the following information):

• Pixel 6a
• Android 14 / GrapheneOS
• App Version 0.88.7-PLAY

Oh yeah, I get exactly the same thing.

It could be an android "feature" rather than an amethyst bug but let's see what others think.

I tried a few things. Android keeps the latest used app in the "media drawer".

Sometimes the media keeps playing even after closing amethyst.. Could be background play functionality but there is no sound from phone.

This will then start playing sound on a new Bluetooth connection like a car.

I agree, this is likely a core Android functionality.

I believe the expected behavior is for the player to disappear when the app goes into the background, which it does.

However, as a user, I often use Amethyst and then put my device to sleep. When I later get into my car and Amethyst is the last app used, I wouldn't expect it to start playing automatically.

In contrast, Primal does not seem to utilize this functionality at all and does not have this issue.

I question whether there is even a real use case for Amethyst utilizing this Android feature, as I doubt anyone is actively using the background player.

Try disabling Now playing notifications?

Try disabling Now playing notifications?

I tried this, unfortunately the issue still occurs

@vitorpamplona I think I managed to reproduce this but I don't have a Bluetooth device to try to fix the issue.
It happens when the Bluetooth is off and you turn it on and connect to a device.
When you do that the video notification starts playing again

I know this may not be ideal, but if you see the video notification bubble, you can tap and hold on it to dismiss it.

Obviously not helpful if the notification isn't visible first though. And still annoying to have to remember to wipe it.
