From 2.9.0, you need to add the following to the android section of the app's build.gradle file:

compileOptions {
  targetCompatibility JavaVersion.VERSION_1_8
}

as per the release notes and latest developer guide. Doing this resolves the issue (you probably need to sync and clean the project after adding this).

Aside: It's pretty unfortunate the failure mode is so obscure, but I don't think that's under our control.

It's hard to say what is causing this with the information you are providing. I wonder if there is any other exception stack trace in the logs.

Did you customize the layout file of the PlayerView in some ways?

Please provide complete information as requested in the issue template. The issue template can be found here.

If you customized the playerView or controller layout it would be useful to be able to look into these. In any case a bugreport taken just after the exception happened would allow us to check whether there are any other exceptions root causing the InflateException.

I got this issue too, today.
Attached sample:

ExoPlayerTest.zip

Any idea why this could happen?

Tested on Pixel 2 with Android P.
Attached bug report file.

When changing to version 2.8.4 of ExoPlayer (and changing the URL, as I got it wrong, to this: https://sample-videos.com/video123/mkv/720/big_buck_bunny_720p_1mb.mkv ) , it works fine.

Please fix this issue.

Attached the fixed version of the project:

@ojw28 Now it says it can't find the repository:

ERROR: Failed to resolve: com.google.android.exoplayer:exoplayer-core:2.9.0

See attached video and sample project.
ExoPlayerTest.zip
Uploading 2018-12-09_23-00-52.zip…

I tried to invalidate cache and rebuild. Didn't work.

@ojw28 So no solution for this?
Or will it get fixed by itself some day soon?
