FirebaseMessaging.getInstance().getToken()

[Rajarajan viswanathan]

Hi,

I have implemented firebase cloud message concept to my app. It works fine when it running in normally, it generate token when i am running the app in testing.

When I build the app for publishing in google play store with singed apk. the token not generated. I don't know why the fcm token not generated. Please guide me, how to fix it.

The below are my code snippet:

FirebaseMessaging.getInstance().getToken()
.addOnCompleteListener(new OnCompleteListener<String>() {
@override
public void onComplete(@NonNull Task<String> task) {
if (!task.isSuccessful()) {
System.out.print("Fetching FCM registration token failed");
return;
}

FCMRegkey = task.getResult();
System.out.print( FCMRegkey);

}
});

app level gradle:
apply plugin: 'com.android.application'
// Add this line for notification
apply plugin: 'com.google.gms.google-services'


android {
compileSdkVersion 31
buildToolsVersion "30.0.3"

}
}
compileOptions {

targetCompatibility JavaVersion.VERSION_1_8
}

Did you use the same google-services.json file when you built and generated the signed apk?

There could be several reasons why the FCM token is not being generated when you build the app for publishing on Google Play Store. Here are a few things you can try to troubleshoot the issue:

1. Make sure that you have correctly added the required dependencies in your app-level build.gradle file.
2. Check if you have enabled the required services in the Firebase console. Go to the Firebase console, select your project, and make sure that the Cloud Messaging service is enabled.
3. Make sure that you have added the required metadata to your app's AndroidManifest.xml file. This includes the google-services plugin, the FCM service, and the internet permission.
4. Check if you have correctly configured your app's SHA-1 key in the Firebase console. Go to the Firebase console, select your project, and add your app's SHA-1 key in the "Settings" > "General" section.
5. If you are using a physical device to test your app, check if the device has a working internet connection.

I hope these suggestions help you resolve the issue. Let me know if you have any questions or need further assistance.
