"App not installed" error after building android app with "expo build:android"

after I ran expo build:android i got the apk file built successfully but when I try to install it in many devices, it is not being installed and it shows "App not installed" error [image].

here is my package.json:

{
  "name": "some-app",
  "main": "node_modules/expo/AppEntry.js",
  "private": true,
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "eject": "expo eject"
  },
  "dependencies": {
    "axios": "^0.18.0",
    "expo": "^31.0.2",
    "react": "16.5.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-31.0.0.tar.gz",
    "react-navigation": "^3.1.2",
    "react-redux": "^6.0.0",
    "redux": "^4.0.1",
    "redux-persist": "^5.10.0"
  },
  "devDependencies": {
    "babel-preset-expo": "^5.0.0"
  }
}
Solution

  • the problem was in the android packager name in my app.json

    so it was like that:

    "package": "com.<myName>.<appName>"

    i replaced myName with the appName like that :

    "package": "com.<appName>.<appName>"

    and it worked like a magic and I was able to successfully build and install the app on multiple devices
