MediaStyle Notification Seek Bar is Black.

[YaarPatandarAA]

Describe the bug
The seek bar that was introduced with Android 10 is black with no progress circle-bubble and timestamp duration. Tested on a Samsung Note 10 Plus and the seek bar is black. Tested on a OnePlus 6T and the seek bar shows perfectly with the proper color match, progress circle-bubble, timestamp duration.

However on the Samsung Note 10 Plus using other apps which use MediaStyle notifications, their seek bars are perfectly fine. So it can't be the device as other apps have perfectly fine seek bar setups.

To Reproduce
Use on Samsung Device?

Error messages
N/A

Expected behavior
The MediaStyle notification should display the Seek Bar with a progress circle-bubble, have the timestamp duration, and should be properly colored like the other information in the MediaStyle notification

I might be able to borrow a Samsung device, although do you know if it works on a particular virtual device?

I tested on a Google Pixel 3 emulator with Android 10 and it works fine no issues as such as the black bar I see. I also just tested on a Samsung Galaxy S10 Plus with Android 10 and I see the same issues as on my Note 10 Plus with Android 10. So it is definitely a Samsung Android 10 thing, sucks...

P.S. I had used the following plugin: https://github.com/gaucidaniel/native-audio
before switching to this one, that plugin worked fine for my device. Might be worth it to look at it to see what he is doing different than this plugin. I tried to decipher the two codes and I couldn't figure it out. If someone has time could you please try and see what is different?

That's a good lead, thanks. Ideally I also will need to reproduce it on my end, though.

Here is something I found just now.

You can reserve real Samsung devices for testing apps, they are somewhere remote but using remote debug bridge they can be connected to your PC as if they where connected via a USB. You can reserve for a max amount of 2 hours, but only 30 minutes for new devices. They give you a limited amount of credits each day so its not an unlimited amount of time you take up, also be sure to select a device in a region closest to you for faster connections.

SeekBar was introduced in Android 10, so if anyone is going to test/debug that is what OS version they should pick for whichever device they want to use.

P.S. I tired my app on their remote devices and still a black seek bar, idk what else I was expecting.

That's cool. Fortunately, it looks like I will be able to get my hands on an actual device.

I have honor 10, and have this issue with Huawei.

Well that’s not good news.
