I’ve made a chat app that uses Firebase’s feature
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
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
You need three keys in order to make it work:
The debug key. Informations here.
The release key. Informations here.
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:
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
