Answer 1

Fist of all you need to download google-services.json:

1. Sign in to Firebase and open your project.
2. Click the Settings icon and select Project settings.
3. In the Your apps card, select the package name of the app you need a config file for from the list.
4. Click google-services.json.

Ok now you have to install cordova-support-google-services:

cordova plugin add cordova-support-google-services --save

Then, you have to put the google-services.json in the root of your project (outside www folder, at the same level), and then the resource-file tag will copy it to platforms/android/app/

Next, put in the config.xml

<platform name="android">
    <resource-file src="google-services.json" target="app/google-services.json" />
 ... 
 </platform>

Note: if you use cordova-android below version 7 specify instead:

target="google-services.json"

Now try again to build!

As mentioned before google-services.json needs to be copied to the proper location. the location changed recently to app/google-services.json. So the config.xml needs to be adapted accordingly to

<resource-file src="google-services.json" target="app/google-services.json" />

Answer 3

Lets' assume you put the google-services.json in src/app folder So relativly to your ionic project it is located at src/app/google-services.json

Now, to be sure it will be copied to the correct location of the build, you have to add a line of code to the config.xml file.

<resource-file src="src/app/google-services.json" target="app/google-services.json" />

Note that the src property of this line should reflect the relative path of the google-service.json file accordingly.

That's as simple as that
