Firebase Phone Auth SHA-1 fingerprint Issue

Question

I had created a sign in page in flutter using phone Authentication. In which i am getting the error:

E/FirebaseAuth(21546): [SmsRetrieverHelper] SMS verification code request failed: unknown status code: 17028 A safety_net_token was passed, but no matching SHA-256 was registered in the Firebase console. Please make sure that this application’s packageName/SHA256 pair is registered in the Firebase Console. I/flutter (21546): This app is not authorized to use Firebase Authentication. Please verify that the correct package name and SHA-1 are configured in the Firebase Console. [ A safety_net_token was passed, but no matching SHA-256 was registered in the Firebase console. Please make sure that this application’s packageName/SHA256 pair is registered in the Firebase Console. ]

I had already get the SHA1 and SHA256 key from the cmd by using the following steps:

1. In cmd, visited the path where java jdk is installed(in my case:C:\Program Files\Java\jdk1.8.0_212)
2. Then pasted the following command and hit enter keytool -list -v -keystore "C:\Users\Mehul Jain.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

After that i got the key as shown in Screenshot.

copied both the keys and pasted in the firebase Console (as shown in Screenshot below)

App is working correctly. And when I tried signing through test mode (i.e. entering the mobile no. and otp) and run the app with the test mode details, the app was working 100%. But if I want to add the mobile number from the app and try to get SMS the error comes on the screen. I had tried various other mobile number but still not worked(mobile number are not entered in test mode).

Solution

• if are using emulator then safety net fails make sure you using a legitimate with Android Device
• it is possible that u using wrong keystore. best method for fnding debug SHA key is Gradle >> signinreport>>rightclick>>run

Yes, from gradile SigningReport different SHA1 key is genrated. But then in CMD why does it shows another key?
