Error while geting Firebase Phone Auth OTP

问题

I am trying to implement Firebase Phone Verification. I have enabled phone verification on firebase console. I have generated keystore and added the SHA signatures to the console.

dependencies:

dependencies {
    def multidex_version = "2.0.1"
    implementation platform('com.google.firebase:firebase-bom:26.0.0')
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.google.firebase:firebase-analytics'
    implementation "androidx.multidex:multidex:$multidex_version"
    implementation 'com.google.firebase:firebase-auth'
    implementation 'com.google.firebase:firebase-core'
    implementation 'com.google.firebase:firebase-analytics'
    implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'

}

phone_verification.dart

                await FirebaseAuth.instance.verifyPhoneNumber(
                  phoneNumber: '+1234567890',

                  verificationCompleted: (PhoneAuthCredential credential) {
                    print('verificationCompleted');
                    
                  },
                  verificationFailed: (FirebaseAuthException e) {
                    print('verificationFailed');
                    if (e.code == 'invalid-phone-number') {
                      print('The provided phone number is not valid.');
                    }
                    else {
                      print('Some error occoured: $e');
                    }
                  },
                  codeSent: (String verificationId, int resendToken) async {
                    print('codeSent');

                    // Update the UI - wait for the user to enter the SMS code
                    String smsCode = '123456';

                    // Create a PhoneAuthCredential with the code
                    PhoneAuthCredential phoneAuthCredential = PhoneAuthProvider.credential(verificationId: verificationId, smsCode: smsCode);
                  
                  },
                  timeout: const Duration(seconds: 60),
                  codeAutoRetrievalTimeout: (String verificationId) {
                    print("Timeout: $verificationId");
                  },
                );

When the above block is executed following error is received. Console Output:

E/FirebaseAuth: [GetAuthDomainTask] Error getting project config. Failed with {

回答1:

Enable Phone option in the Firebase Console under Authentication

Your problem related to SHA1 and SHA256 keys. You have to add them to authenticate your certs.

Goto

• Firebase Console of your project
• Authentication
• Project Setting (From Setting button near Project Overview)
• Add fingerprint
• Add SHA-1 and SHA-256 values of your keystore.

You can get keystores from gradle like this.

./gradlew signingReport
