How I Fixed an Expo SDK 54 Android Build with SDK 55 Packages Mixed In
This is an English translation of my original article on Qiita . An Android build failed in an Expo SDK 54 app. The project still used Expo SDK 54, but several Expo packages had been upgraded to versions intended for SDK 55. TypeScript checks passed, and the development server ran normally. I did not catch the mismatch until EAS Build reached the native build step. What the dependency list looked like The relevant part of package.json looked like this: { "dependencies" : { "expo" : "~54.0.33" , "expo-apple-authentication" : "~55.0.13" , "expo-dev-client" : "^55.0.27" , "expo-image-picker" : "^55.0.18" , "expo-linking" : "^55.0.12" , "expo-notifications" : "^55.0.19" , "expo-splash-screen" : "^55.0.18" } } The expo package was still on version 54, while several related packages were on version 55. This happened because those packages had been installed individually using their latest versions. The package version does not always match the Expo SDK number. For example, Expo SDK 54 uses expo-notifications 0.32 and expo-splash-screen 31. Looking only at major version numbers is not enough to determine SDK compatibility. Start with expo install --check Expo CLI can compare the installed packages with the versions expected by the current SDK: npx expo install --check It can also return the result as JSON: npx expo install --check --json This is more reliable than trying to infer compatibility from package.json manually. Expo CLI can fix the versions automatically: npx expo install --fix npx expo-doctor I wanted to review each change, so I used the reported versions to update package.json myself. The versions I changed These were the main corrections: - "expo-apple-authentication": "~55.0.13" + "expo-apple-authentication": "~8.0.8" - "expo-dev-client": "^55.0.27" + "expo-dev-client": "~6.0.21" - "expo-image-picker": "^55.0.18" + "expo-image-picker": "~17.0.11" - "expo-linking": "^55.0.12" + "expo-linking": "~8.0.12" - "expo-notifications": "^55.0.19" + "expo-notifications"
