I'm not an android dev so can't really help to fix it, any ideas?

[Guichaguri]

The most recent versions of the support lib removed/changed a few classes that I use. For now, use the older versions instead.

[haswalt]

thanks for the reply. I don't think I can downgrade our support lib version, we have a few other libs that depends on min 26.0.0.

[jankarres]

Thank you for your great work, @Guichaguri and @dcvz. I have to join @haswalt unfortunately that < 26.0.0 is not possible for some popular libraries, like the react-native-fbsdk.

I tried to implement the new API of NotificationCompat.Builder() with my limited Java, but I had to find out that this would cause further problems.

I would like to switch from react-native-sound and react-native-music-controls to react-native-track-player and would be grateful for a compatibility to 26.0.0.0.

[haswalt]

@jankarres I've got a fork over here https://github.com/BlueBambooStudios/react-native-track-player that we've got at least building, it's still not working fully due to some isues with service changes but we're working towards a fix.

I'm afraid my fork is a bit of a mess at the moment whilst I work through getting it working as well as some additional features we've added. Hopefully of use

[jankarres]

@haswalt Awesome, thanks for your work. But there is actually still a major issue? If I execute

import TrackPlayer from "react-native-track-player"; [...] TrackPlayer.setupPlayer();

The app crashed with the following stack. Actually a issue you have, too?

[haswalt]

@jankarres ah yes. so it's very WIP :)

I think I added some deps to the gadle config in my parent project that make it work. I'l try adding them to the repo so you get them automatically.

give me 5 minutes

[haswalt]

@jankarres I've pushed a change to my fork that should fix it. I've also opened up issues as we might want to continue the discussion over there.

[ashokkumar88]

For me the crash was causing due to another library which was also using exoplayer. I removed the other library and it worked fine.

[jeongjuwon]

I have same issue as you had .
You can migrate NotificationCompat version to v4

Please see that pull request #205 I created
It will works fine.

You can add directly my fork repository in your package.json if my pull request will not be merged.
Please see the example below.

dependencies: {
    "react-native-track-player":
      "git+https://github.com/rm3rdmodules/react-native-track-player.git#dev"
}
