Failed to read Firebase options from the app's resources.

Hi all,

I'm working on unity project that will post SCORE data to Firebase realtime database (https://assetstore.unity.com/packages/tools/network/cross-platform-leaderboard-151816), and it works when I test on UnityEditor, but not on real mobile android device.

Here is the logcat:

02-23 11:34:41.889 13194-13271/com.devzuky.dumpy E/Unity: Failed to read Firebase options from the app's resources. Either make sure google-services.json is included in your build or specify options explicitly.

I downloaded the google-services.json from firebase project, and copy to Assets folder, but cannot work. Tried to export to gradle project and there is a file no file google-services.json, but it has a file google-services-desktop.json ? Did I make something wrong, please help.

 

Please help !!!

 

I solved it by adding below in the mainTemplate.gradle



sourceSets {
main {
res.srcDirs += '<fullpath>\\Assets\\Plugins\\Android\\Firebase\\res\\values\\googleservices.xml'

}
}

 

hi, have you a sample to show to me, i have the same problem but i don't understand how to implement correctly your solution, thanks ;-)

 

apply plugin: 'com.android.library'
**APPLY_PLUGINS**

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
**DEPS**}

android {

sourceSets {
main {
//res.srcDirs += '<fullpath>\\Assets\\Plugins\\Android\\Firebase\\res\\values\\google-services.xml'

???

//res.srcDirs += 'Assets/Plugins/Android/Firebase/res/values/google-services.xml'

}
}


compileSdkVersion **APIVERSION**
buildToolsVersion '**BUILDTOOLS**'






compileOptions {

I am having same error: its named as google-services-desktop.json.

 

In Unity 2020, all Android resources must be in directories with a .androidlib suffix. If your project is using a Firebase SDK that generates an Assets/Plugins/Android/Firebase directory, rename it to Assets/Plugins/Android/Firebase.androidlib. Make sure it contains AndroidManifest.xml, project.properties and res/values/google-services.xml.

 

Thanks a lot @I_Gamer_Karthi you just saved me.

I had errors like this when trying to connect with Firebase :

NullReferenceException: Object reference not set to an instance of an object.

and I saw also this error :

Failed to read Firebase options from the app's resources. Either make sure google-services.json is included in your build or specify options explicitly.

I was getting crazy after one day I didn't understand why Firebase was not working anymore migrating from Unity 2019 to Unity 2020.
Renaming the folder to Firebase.androidlib is what solved my issue.

 

In my case Special sign in filepath caused this error!

 

This solved my issue, thanks @I_Gamer_Karthi you saved my time and commitment

 

Thanks a lot, your hint solve my issue. Take a look also to package name if you come from 2019 unity version because 2020 change package name on the base of game parameters.

 

it seems the solution game karthi solve this problem,
i am little bit late here but stuck in this problem..
i dont know how to implement the solution u gave me
if anyone active please show me step by step.
thnk u very much..

 

I still have that issue and renaming it from firebaseapp.androidlib to firebase.androidlib doesnt seem to work

 

For everyone who have the folder named "Firebase" inside "Assets/Plugins/Android" above listed solution by @I_Gamer_Karthi works. If you dont even see the "Firebase" folder and keep getting this error "Assembly 'Packages/com.google.firebase.app/Firebase/Editor/Firebase.Editor.dll' will not be loaded due to errors: Unable to resolve reference 'UnityEditor.iOS.Extensions.Xcode", all you need to do is restart unity after installing Firebase SDK.

 

I get the same error "failed to read firebase options from the app's resources" when building, none of the solutions above work for me. Did anyone figure it out?

 

IS it working or not?

 

Can this Assets/Plugins/Android/Firebase.androidlib AS LIKE IT , I mean you using a new name of folder with using '.' it is same as shown by you?
