[question] firebase-core function initializeAppWithPath(path) for Android

[erodriguezh]

Hello,

I am trying to load a different firebase configuration per environment. I figured that using the initializeAppWithPath() I could point to the Google Services config files for dev and prod for Android and iOS.

For iOS It worked out of the box using the path res://, it points to the App_Resource/iOS folder.

However, for android I do not seem to be able to load the google-services.json at all.

I tried with path res://, ~/ and resolving the path myself and I always get the error firebase.init error: Error: com.tns.NativeScriptException: Failed to find module: "/data/data/com.nativescript/files/app/firebase/dev/google-services.json", relative to: app/

Would you guys be so kind and provide some examples for Android on to which folder the paths res://, ~/ point in the code base?

I am using Angular flavor.

Best

@erodriguezh iirc you can drop the into let say App_Resources/Android/src/debug by doing this it will only be used for your debug apps.

Hi @triniwiz,

Thanks for the tip. The reason that I was asking for example on how to load a file on Android using res:// or ~/ is to have both Android and iOS implementations consistent. While having App_Resources/Android/src/debug for debug and App_Resources/Android/src/prod for production on Android will work out of the box, This approach did not work on iOS. On iOS I will have to point to the file specifically using initializeAppWithPath().

The code would roughly look like this.

    let initializeFirebase;
    if (isAndroid) {
      initializeFirebase = firebase().initializeApp();
    }
    if (isIOS) {
      initializeFirebase = firebase().initializeAppWithPath('res://firebase/dev/GoogleService-Info.plist');
    }
    initializeFirebase.then(
      (firebaseApp: FirebaseApp) => { console.log('firebase.init done'); },
      error => { console.log(`firebase.init error: ${error}`); }
    );

I believe this is a bug on my end with reading the file from app resources

Try dropping the config into App_Resources/Android/src/main/res/raw

[erodriguezh]

I added the config file to the following path App_Resources/Android/src/main/res/raw/debug/google-services.json

I tried with the following paths

firebase().initializeAppWithPath('res://debug/google-services.json'); firebase().initializeAppWithPath('res://raw/debug/google-services.json');

Both returned this error:

firebase.init error: Error: java.lang.NoSuchFieldException: No field raw/debug/google-services.json in class Lcom/nativescript/R$raw; (declaration of 'com.nativescript.R$raw' appears in /data/app/~~ahUHybxEYkwOp7GGWOAGug==/com.nativescript-8dUx9vz5oYzaAcDegJH4mQ==/base.apk!classes2.dex)

Then I tried with

firebase().initializeAppWithPath('~/debug/google-services.json); firebase().initializeAppWithPath('~/raw/debug/google-services.json);

Both returned this error:

firebase.init error: Error: com.tns.NativeScriptException: Failed to find module: "/data/data/com.nativescript/files/app/raw/debug/google-services.json", relative to: app/

[triniwiz]

Try the following firebase().initializeAppWithPath('res://google-services');

[erodriguezh]

I found out a few things

1. There are requirements for the naming convention of the file. E.g: Using dashes is forbidden.

Execution failed for task ':app:mergeDebugResources'.
/nativescript/platforms/android/app/src/main/res/raw/google-services.json: Error: '-' is not a valid file-based resource name character: File-based resource names must contain only lowercase a-z, 0-9, or underscore

2. This almost works

Add the config file to the following path App_Resources/Android/src/main/res/raw/google_services.json

Then call it from the code firebase().initializeAppWithPath('res://google_services')

But it throws the following error

JS: firebase.init error: Error: java.lang.IllegalStateException: FirebaseApp name [DEFAULT] already exists!

Then I figured out that I had a google_services.json in the debug folder, so I removed it, but then I remembered that the first time you compile after running ns clean, if there is no google_services.json on the debug folder it throws the following error.

Execution failed for task ':app:processDebugGoogleServices'.
File google-services.json is missing. The Google Services Plugin cannot function without it.

We have the chicken or the egg problem :sweat_smile:
