Android IllegalThreadStateException with SDK 44


Unfortunately I don’t know where is the problem, I got this error in Google Play Developer Console in 3 different apps, built with EAS and SDK 44. Could it be a problem with expo-updates package?

Managed or bare workflow? If you have ios/ or android/ directories in your project, the answer is bare!


What platform(s) does this occur on?


SDK Version (managed workflow only)



 Expo CLI 5.0.3 environment info:
      OS: Windows 10 10.0.19043
      Node: 14.18.1 - C:\Program Files\nodejs\node.EXE
      npm: 8.1.4 - C:\Program Files\nodejs\npm.CMD
      Android Studio: Version     2020.3.0.0 AI-203.7717.56.2031.7621141
      babel-preset-expo: 9.0.1 => 9.0.1
      expo: ^44.0.0 => 44.0.0
      react: 17.0.1 => 17.0.1
      react-native: 0.64.3 => 0.64.3

Reproducible demo

This problem occurred on Android 11 and Android 10, with Samsung Galaxy A12, Galaxy A50, Galaxy A71, Galaxy S9, Galaxy S10, Galaxy S20+ 5G.

Command used to build and submit: eas build -p all --profile my-profile --auto-submit

UPDATE: I’ve deployed a new build with expo build:android --no-wait -t app-bundle and I don’t have this problem so maybe the problem is due to EAS build or specifically to expo-updates.

  1. Hi all, thanks for the report and sorry for the delay on our end. We’ve got a fix in the works that should be out by the end of the week (hopefully sooner). Many thanks to @jparkrr for the repo which was very helpful in finding the cause and testing a fix quickly.
