java.lang.IllegalStateException: FirebaseApp name [DEFAULT] already exists! about metrica-push-plugin-unity

Hi!
Use ymp_firebase_app_id instead of ymp_firebase_default_app_id and ymp_gcm_sender_id instead of ymp_gcm_default_sender_id in AndroidManifest.XML

[dekart]

Thanks. The error has changed to:

Add in AndroidManifest:
<meta-data android:name="ymp_firebase_api_key" android:value="API_KEY"/>
API_KEY — App key in Firebase. You can find it in the current_key field of the google-services.json file. You can download the file in the Firebase console.

@NesterovichAlexey I've just checked it, the value is already there, but the error still appears.

mata-data named ymp_firebase_api_key only works with AppMetrica Push SDK Android version 1.4.0.
But the Push Unity plugin uses version 1.1.0.
To upgrade to unity SDK version to 1.5.1 (now the latest) is a bit difficult.
I can help with that. What is the version of Unity and is there a file Assets/Plugins/Android/mainTemplate.Gradle?

[dekart]

1. We use Unity 2019.3.0b9
2. There's file mainTemplate.Gradle.DISABLED , and it's marked as "generated by unity"

[NesterovichAlexey]

Cool! With this version, everything will be easier.
The file ends with DISABLED, so you used it before, but now you don't.
You will need to start using it again, you can remove DISABLED or select Custom Gradle Template in Unity.

And add to the dependencies block:

implementation ("com.yandex. android: mobmetricapushlib:1.5.1") {
    exclude group: "com.yandex. android", module: "mobmetricalib"
}
implementation " com.google.firebase:firebase-messaging:18.0.0"
implementation " com.google.android.gms: play-services-base:16.1.0"
implementation " com.android.support:support-v4:28.0.0"

When creating this file from scratch and adding these lines I succeeded:
mainTemplate.txt

Need to still from folders Assets/AppMetricaPush/Plugins/Android to remove all except appmetrica-push-plugin.aar

[dekart]

Moving whole project to manual gradle support seems to be a serious move that requires a lot of hassle. At least, it stopped build after the switch and I'm not sure that it's a good idea to keep digging this way.

Do you have any idea when the Unity plugin will start supporting the new version?

[dekart]

UPD: I've managed to build the app with custom gradle template, but now I receive this error message:

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.app.NotificationChannel"
