I’m trying to apply minify to the release build. What are the lines needed in Proguard for Bitmovin to work?

- For player, I seem to need to add: -keep class com.bitmovin.player.\*\* { \*; }
- For analytics, I seem to need to add: -keep class com.bitmovin.analytics.\*\* { \*; }

Or, is this documented somewhere in Bitmovin?

Hi @davidy

Thank you for your question.

For player, we have documented Proguard in this readme section: [bitmovin-player-android-samples/README.md at main · bitmovin/bitmovin-player-android-samples · GitHub](https://github.com/bitmovin/bitmovin-player-android-samples/blob/main/README.md#proguard-configuration)

For analytics, you are correct, that adding the noted information is known to work:  
`-keep class com.bitmovin.analytics.data.** { *; }`

I hope this helps
