Change package name (not only applicationId) for build flavor

Question

When building multiple whitelable apps on the same codebase it's easy to use the build flavor mechanism of Android Studio. I can easily set a new applicationId in build.gradle file.

android {
    productFlavors {
        original {
            applicationId "com.original.myapp"
        }
        whitelable {
            applicationId "com.whitelable.myapp"
        }
    }
}

Everything's nice BUT the package name of the whitelable app is still com.original.myapp and the component name of the main activity is com.whitelable.myapp/com.original.myapp.MainActivity. Everybody can see that the whitelable app is build upon the original app.

Is the a way to replace the package name for the build flavor so the original package name at least doesn't appear on the flavored app's component names?

The accepted answer from there only suggests using ${applicationId} instead of ${packageName} which is obviously not enough for my purpose. — Alexey Ozerov, Oct 09 '17 at 13:18

The question was asked a long time ago but I'd like to answer it for new folks who will investigate. First you have to create 2 versions with Flavors. Then, if you are using it, you need to create the data for the version you just created in the "client": [] section in your google-service.json file. (You can also create a separate google-service.json file for both in their own package folders.) Then use ${packageName} instead of explicitly typing your package path in the Manifest file with your package path. I was able to create 2 completely different packageNames by following this way.

Flavors;

flavorDimensions "default"
productFlavors{
    product1{
        applicationId "com.product.package"
    }

    product2{
        applicationId "com.white.label"
    }
}

google-service.json; I cannot share the google-service.json file, but the data under "client" in the google-service.json file you will receive for your new project via Firebase should be copied and added to the "client" as the second data under the google-service.json file in your project. Sample;

"client": [
{
  "client_info": { //Old App Info
    data...
  },
  ...
},
{
  "client_info": {
    //New App Info
    data...
  },
  ...
}
]

Manifest;

com.project.package.fileprovider

use this instead

${packageName}.fileprovider

Please include the relevant parts of the sample google-service.json and Manifest files in your answer. — Alexey Ozerov, Sep 22 '22 at 12:13
