Thank you.
Hope it helps!


Thank you very much for another great extension!

This is going to be a popular extension. When Auth support is added, it should be a paid extension.

But I am confused whether to integrate Firebase Authentication in this extension or keep that separate.
First one seems good from perspective of user as apk size won't be increased much.

I got this with the companion

Managing the manifest for different Firebase extensions can be a challenging task. As far as I remember, there are some registrars that need to be present in the manifest to make the respective Firebase service work. The GMS version meta tag may generate error while publishing if compiled into the app through both extensions.

It works fine, just compiled a project with Crashlytics + Storage extensions together.

I agree connecting two different services together will be challenging task and I might have to manipulate some firebase and gms classes. So I'll go with the easier option to combine both features and rename this extension.

It may generate error while publishing, play store won't accept the APK if the GMS meta-tag is duplicated.

If someone is using this extension in his/her project and would like to continue with the update then I'll suggest to create a backup immediately.
Update will be breaking a lot of things.

What I wish To Do:

  • Change extension name to FSA
    acronym for Firebase Storage and Authentication combined
  • Rename/Remove some events and methods
  • Add Firebase Authentication

Where can i find it?


Thank you

It does not work.
I don't know why.
Attached is my block:

@ason_J you missed it.

Sorry, I didn't look carefully

Will this file in resources be safe in the compiled apk? Or will keys written in code be more secure?

It will be safe as much as assets are.
