React native Expo Version code 1 has already been used. Try another version code

Question

After updating my app I am trying to upload my expo app to the playstore but getting error again and again. I changed the version in app.json version": "2.0.0" and also try this version": "1.0.1" and version": "1.0.2". I have no idea why it is showing me this error.

Answer The ios.buildNumber and android.versionCode distinguish different binaries of your app. Make sure to increment these for each build you upload to the App Store or Google Play Store.

see this doc for information on "versionCode" docs.expo.dev/classic/building-standalone-apps/… — brentvatne

You need to increase the android versionCode and iOS buildNumber, not the version string.

"ios": {
  "bundleIdentifier": "com.yourcompany.yourappname",
  "buildNumber": "1.0.0" //increase it for iOS
},
"android": {
  "package": "com.yourcompany.yourappname",
  "versionCode": 1 //increase it for android
}

There is an automated way to do this where expo does it for you. It prevents wasting time & resources of rebuilding again when you forget to update those versions.

In the eas.json the "autoIncrement": true does the trick!

{
  "cli": {
    "appVersionSource": "remote"
  },
  "build": {
    "staging": {
      "distribution": "internal",
      "android": {
        "buildType": "apk"
      }
    },
    "production": {
      "autoIncrement": true
    }
  }
}

here is more on the docs with another option for local instead of remote: https://docs.expo.dev/build-reference/app-versions/

Worth noting that autoIncrement isn't available if you are using app.config.js in lieu of app.json

Thanks. Google play console didnt accept the the solution with {"android": {"versionCode": 2}}. Autoincrement with expo did the trick.
