Create Android App in Firebase Project

After creating a firebase project, in this project we can create several apps with different configuration, here we will create MeGooLive Android App.

Create MeGooLive Android App​

  • Click android icon

  • After that we are required to fill in three information about our app, Package Name, App Name, and SH1 Key

    Example banner

  • first we need the package name of our app, to get the package name of our app

Get Package name​

  • in your Project Flutter mee_goo_live, which was already open using visual studio code, or Android Studio
info

Package names in Android serve as unique identifiers for your app. They follow these conventions:

  • Must have at least two segments (one dot)
  • Written in all lowercase
  • Each segment should start with a letter
  • Only letters, numbers, and underscores are allowed
  • Common format: com.companyname.appname

Examples:

  • ✅ com.google.android
  • ✅ io.flutter.myapp
  • ✅ com.company.app_name
  • ❌ com.MyApp (uppercase not allowed)
  • ❌ com.my-app (hyphens not allowed)
  • ❌ com (needs at least two segments)
  • For your app, choose a package name that follows this structure:
    • First segment: Domain extension (com, io, org)
    • Second segment: Your company/organization name
    • Third segment: Your app name
    For example: com.meegoo.live
warning

Once you publish your app on the Google Play Store, the package name cannot be changed. Choose carefully!

  • we will change the default package name of this app to your package name, this will be very easy and fast because this project already uses change_app_package_name flutter package https://pub.dev/packages/change_app_package_name

  • run the command below, but first change com.mycompany.myappname, to your package name

flutter pub run change_app_package_name:main com.mycompany.myappname
  • if successful it will look like this

  • so after that, the package name in your mee_goo_live app has all changed, and you can copy the package name to firebase
  • and add your App nickname

  • for debug signing, we can fill it later, just click register app

  • after that you have to download the google-service.json file

Example banner

  • and copy the file into your mee_goo_live flutterproject in the directory android/app/

Folder to copy the file

info

if there is already a google-services.json file in that folder, replace it with the new file you just downloaded. Make sure the filename is exactly google-services.json without any typos.

  • after that click next in firebase,
