回答1:
Fist of all you need to download google-services.json:
- Sign in to Firebase and open your project.
- Click the Settings icon and select Project settings.
- In the Your apps card, select the package name of the app you need a config file for from the list.
- 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" />
回答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
回答4:
Place the google-services.json file in your project's root and make sure it will be copied to the www directory by adding this line to the config.xml file (between the <platform name="android">...</platform> tags):
<resource-file src="google-services.json" target="google-services.json" />
then run ionic cordova prepare android again.
回答5:
From your dropdown select
- project
- then go to app folder
- then paste your file inside app folder.
- clean build and rebuild again
回答6:
I have placed google-services.json in Platforms/Android/ folder and run ionic cordova build android. Its working.
回答7:
You have to copy the google-services.json file into platforms/android/app folder. Executing a android run will work fine.
(You can download the google-services.json from firbase project settings.
回答8:
Copy your google-services.json inside of your ionicProject/src then try to remove and reinstall the ionic-firebase plugin again.
