This problem only occurs in the sample-app-compose project. Sample-app is normal.

I noticed that, if you start a call without e2ee, then hangup, then start one with e2ee, it doesn't crash. It crashes only if you start a call immediately with e2ee. Seems like something isn't loading correctly.

[davidliu]

Ah, you'll probably need to call LiveKit.init(appContext) prior to using E2EE, depending on how your code is setup. Usually we handle this when creating the room, but some native classes might be referenced while you're setting up your options beforehand.

I'll fix up our samples and documentation to reflect this.

[tamimattafi]

@davidliu Adding LiveKit.init(this) to io.livekit.android.composesample.SampleApplication in onCreate fixed the crash. Thank you!
