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

Question

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"…

Accepted Answer

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.

if you need know more about versionCode, see this documentation.
