java – Firebase UI authentication with google fails with message (code:10 message:10)-Exceptionshub

Posted by: admin February 26, 2020 Leave a comment


I’ve made a chat app that uses Firebase’s feature Real-time database.
I face a problem with google authentication. The problem started when I downloaded the app from the Play Store, the authentication was working perfectly when I was running the app in debug mode. When users try to sign in they get a toast message code:10 message:10.

I would like to note here that: I’ve added the SHA1 fingerprint. How can I solve this?

*Not sure if this is helpful but I’ve followed step by step this tutorial

How to&Answers:

You need three keys in order to make it work:

  1. The debug key. Informations here.

  2. The release key. Informations here.

  3. Google Play App signing key. Informations here.

All these keys are needed in order to make the sign-in process work.

Other informations here.


After generating SHA1 for release key, I forgot downloading the new google-service.json file that caused the same error.

Make sure you follow the instruction https://developers.google.com/android/guides/client-auth to generate and add debug/release SHA1 to firebase console and download google-service.json after updated.

If you use Use app signing by Google Play option, you need an additional step:

After uploading app into google play console, go to Release management > App signing, copy SHA1 and paste to firebase console

Make sure you have added signed SHA1. If you are using debug one then it will not gonna work for live apk.

You need to put “debug.keystore” in this path C:\Users\USER_FOLDER_NAME.android

then in Android studio follow the below steps
1. Run your project
2. Click on Gradle menu
3. Expand Gradle Tasks tree
4. Double click on android -> signingReport

You can see SHA in Run Tab
