I know this sounds like a repeated question but I have tried all the solutions I could find here. The problem is I am not able to log in using google-firebase process in my android app. I am keep getting com.google.android.gms.common.api.ApiException: 10: error. I have also tried the process after regenerating the SHA1 key from the android studio. I have done following until now

I have followed step by step procedure of Google Sign in Auth firebase docs. I have generated my debug SHA1 fingerprint using default android key store. I have created OAuth 2.0 client ID in Google API console, both the android client id and the web client and while sending the request, I am using the web client id as instructed in the guide. When this did not work I have regenerated the signing key in the android studio, Build->"Generate Signed APK" using debug. And repeated the whole process.

Yet no luck. Could someone help me with this?

Thanks in advance!

Answer:-

Here the issue was I had already used the SHA1 hash before for a different app using a different google account. And I was able to solve it by deleting the default debug.keystore file in the SDK folder which led the android studio to create a new keystore file with a new key. I created a new Google project in Google API console and used the new key hash for its credentials. Then I cleaned and rebuild the project inside studio after uninstalling the previous app from the emulator. And voila everything worked like a charm. Thanks anyway for your suggestions!

  • Check if libraries in grade are all in same lastest versions. (this logcat informations are useless) https://firebase.google.com/docs/android/setup?authuser=0 – Diego Venâncio Mar 09 '18 at 17:58
  • implementation 'com.google.android.gms:play-services-ads:11.8.0' implementation 'com.google.android.gms:play-services-auth:11.8.0' implementation 'com.google.firebase:firebase-core:11.8.0' implementation 'com.google.firebase:firebase-database:11.8.0' implementation 'com.google.firebase:firebase-storage:11.8.0' implementation 'com.google.firebase:firebase-auth:11.8.0' Yes I have same version for all libs – Abdullah Muhammad Mar 09 '18 at 18:04
  • I think the issue is I am using my debugkey for another project in google API console. – Abdullah Muhammad Mar 10 '18 at 05:57
