Failed resolution of: LogSessionId

[AradiPatrik]

Version

Media3 pre-release (alpha, beta or RC not in this list)

More version details

1.8.0-alpha01

Devices that reproduce the issue

Samsung S9 - Android 9 Xiaomi Redmi Note 8 Pro - Android 10

Devices that do not reproduce the issue

Galaxy S23 Ultra Android 14

Reproducible in the demo app?

Not tested

Reproduction steps

Start a media3 transformer to render a video on a release build with minify enabled using the current alpha version of the library

I've already added

-keep class android.media.metrics.LogSessionId

To my proguard-rules.pro

It seems like LogSessionId requires api level 31 anyway so it's no wonder older devices can't find the class definition

Expected result

Transformer renders the video

Actual result
