电话身份验证 google firebase 失败

Question

I used google firebase phone authentication this is my code: https://codeshare.io/5MrgVy until yesterday it worked, today instead every time I enter a phone number the toast appears which should appear in this case:

public void onVerificationFailed (FirebaseException e) {loadingBar.dismiss ();

                Toast.makeText (RegistrationActivity.this, "Invalid number entered ...", Toast.LENGTH_SHORT) .show ();
                relativeLayout.setVisibility (View.VISIBLE);


                continueAndNextBtn.setText ("Continue"); // Continue
                codeText.setVisibility (View.GONE);


            }

Lately I did a referactor to change the name of the project package, and after doing this it gave me this error: No matching client found for package name 'com.conta.ftof' I solved that error by replacing the old packages inside google-services.json with the new one. I told you this because I'm afraid this is the cause. How could I fix the authentication fact?

edit:

I noticed this strange thing in the build output:

activity#com.google.firebase.auth.internal.FederatedSignInActivity@android: launchMode was tagged at AndroidManifest.xml: 24 to replace other declarations but no other declaration present

Answer 1

there can be many reasons of the failure. you can try the folowing

• if you had been testing on emulator. it wont work
• if you had beeen testing using the same phone number again and again then firebase ll block your number for 24 hrs and sometimes even more just to stop the abuse. for overcoming the quote exceed error you can create test mobile numbers in fireabse console => https://firebase.google.com/docs/auth/android/phone-auth#test-with-fictional-phone-numbers
• internet connection
• some android certificate error

try checking every case

[EDIT]: FIREBASE PHONE AUTH ERROR HANDLING

try the following code it ll help you a bit

@Override
public void onVerificationFailed(FirebaseException e) {
    if (e instanceof FirebaseAuthInvalidCredentialsException) {
        // Failed to verify due to wrong format mobile number
    } else if (e instanceof FirebaseTooManyRequestsException) {
        // Failed to verify due to usage over quota limit
    }
}

Answer 3

I solved. The cause was that I had changed the package name and therefore would have to change the package name in firebase as well. I created a new app on firebase and this time I put the right package name, replacing the google-services.json file with the old one ... Now it works!
