Around midnight UTC time ExoPlayer package has been removed from the registries we use to download our native dependencies. This resulted in
Could not find com.google.android.exoplayer:exoplayer-core:2.6.1. errors. Around 9 AM UTC we’ve deployed a fix to SDK30 and 31 standalone app builders which included the https://github.com/expo/expo/commit/28a9c97257e4681e28056b21cc1eda33fbec9c1f commit, adding the BinTray repository with ExoPlayer dependencies. The problem affected only SDK30 and 31, because older versions of the SDK required older version of ExoPlayer which hasn’t been removed from the repositories.
Unfortunately, about that time
com.google.gms:google-services:3.2.1 has also been removed from either Google or JCenter registries, resulting in errors on all SDKs. Around 12 PM another fix has been deployed, adding BinTray’s
android-tools repo (https://github.com/expo/expo/commit/b2c00cb8c177e55d78548173d3ef3d35ca314ee3)..)
Since then we’ve seen no other occurrences of these issues. Sorry for the inconveniences!
