in app.json [ inside expo--android ] android package name missing

I want my android package name

  "expo": {
    "name": "tinder",
    "slug": "tinder",
    "version": "1.0.0",
    "orientation": "portrait",
    "icon": "./assets/icon.png",
    "splash": {
      "image": "./assets/splash.png",
      "resizeMode": "contain",
      "backgroundColor": "#ffffff"
    "updates": {
      "fallbackToCacheTimeout": 0
    "assetBundlePatterns": [
    "ios": {
      "supportsTablet": true
    "android": { /*  android package name missing */
      "adaptiveIcon": {
        "foregroundImage": "./assets/adaptive-icon.png",
        "backgroundColor": "#FFFFFF"
    "web": {
      "favicon": "./assets/favicon.png"

Just just need to add it there yourself.

Or else if you build with eas build then it will prompt you for the package name and add it for you.

By the way, if you want to publish this to the App/Play stores, they will likely object to you calling the app “tinder”, since there is already a very well known app with the same name.
