Expo React-Native Android build not updating Version Code for Google Play

Posted by: admin May 14, 2020 Leave a comment


I built a React-Native android app and uploaded to Google Play, which worked fine.

Now I have a new build I am trying to upload (had no issues uploading to itunes Connect), and Google Play is giving me this error:
“You need to use a different version code for your APK or Android App Bundle because you already have one with version code 1.”

After each build, I have updated the version in app.json, and I have tried updating the version in package.json as well. I’ve done a directory-wide search for ‘versionCode’ and there are no instances. A directory-wide search of ‘version’ turned up over 2,000 results, and I scrolled through all of them, and did not see anything specific to android build. And I did NOT have an issue with iOS build.

I have tried publishing the app first using Max Expo XDE, and I am building it in command line with “exp build:android”.

I have the following in my app.json:

  "expo": {
    "name": "Placeholder",
        "sdkVersion": "27.0.0",
        "privacy": "unlisted",
        "orientation": "portrait",
        "icon": "./assets/img/AppIcon.png",
    "version": "0.3.4",
    "ios": {
      "bundleIdentifier": "com.placeholder.placeholder"
    "android": {
      "package": "com.placeholder.placeholder"

and my package.json is as follows (and npm install has been run):

  "name": "placeholder",
  "version": "0.2.0",
  "private": true,
  "devDependencies": {
    "jest-expo": "~27.0.0",
    "react-native-scripts": "1.14.0",
    "react-test-renderer": "16.3.1"
  "main": "./node_modules/react-native-scripts/build/bin/crna-entry.js",
  "scripts": {
    "start": "react-native-scripts start",
    "eject": "react-native-scripts eject",
    "android": "react-native-scripts android",
    "ios": "react-native-scripts ios",
    "test": "jest"
  "jest": {
    "preset": "jest-expo"
  "dependencies": {
    "axios": "^0.18.0",
    "expo": "^27.0.1",
    "native-base": "^2.4.3",
    "react": "16.3.1",
    "react-native": "https://github.com/expo/react-native/archive/sdk-27.0.0.tar.gz",
    "react-native-svg": "^6.3.1",
    "react-navigation": "^2.0.0",
    "redux-thunk": "^2.2.0",
    "socket.io-client": "^2.1.0"
How to&Answers:

I also experience this issue, I resolved it by adding versionCode to my app.json under android. For instance,

“android”: {
“versionCode”: 2

Notice that the ‘2’ does not have quotation marks.


needed to add “versionCode” to the “android” section of app.json specifically…


According to Deploying to App Stores 1, you need to follow the instructions from Building Standalone Apps. The “versionCode” is indeed referenced in 2 and it is an option specific to the Android section: 3.
