Los Kayos :
So I had my Phone Verify working since I updated my Firebase last week. Since then I'm facing the problem that in my linking process where I'm connecting the users email to the phone number doesn't work anymore: java.lang.IllegalArgumentException: Cannot create PhoneAuthCredential without either verificationProof, sessionInfo, ortemprary proof. I've seen some users with the same problem but nobody with a solution.
I tried to rewrite the whole Code but the problem is still there. Has Firebase changed something in the linking process? As I have seen in the Firebase Linking Documentation, the section about Phone Number linking was removed.
Is something wrong with my code or is it a problem with firebase?
Firebase Versions I'm using:
implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.google.firebase:firebase-messaging:17.6.0'
implementation 'com.google.firebase:firebase-perf:16.2.5'
implementation 'com.android.support:support-compat:28.0.0'
implementation 'com.google.firebase:firebase-auth:16.2.1'
implementation 'com.google.firebase:firebase-storage:16.1.0'

Here how to use Firebase Phone Authentication from Firebase docs
https://firebase.google.com/docs/auth/android/phone-auth
and linking Authentication provider
https://firebase.google.com/docs/auth/android/account-linking
//please notice, mCallback.onVerificationCompleted will automatically called
//if verification code already send to your phone
//(Maybe not called in some case)
mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
@Override
public void onVerificationCompleted(PhoneAuthCredential credential) {
linkPhoneAuthToCurrentUser(credential);
}
@Override
public void onVerificationFailed(FirebaseException e) {
//show error
}
@Override
public void onCodeSent(String verificationId,
PhoneAuthProvider.ForceResendingToken token) {
//save id and token in case you need to resend verification code
}
};
//call this to send verification code
//parameter include country code
private void sendVerificationCode(String phonenumber) {
PhoneAuthProvider.getInstance().verifyPhoneNumber(
phonenumber, // Phone number to verify
60, // Timeout duration
TimeUnit.SECONDS, // Unit of timeout
this, // Activity (for callback binding)
mCallbacks); // OnVerificationStateChangedCallbacks
}
//link auth with credential
private void linkPhoneAuthToCurrentUser(PhoneAuthCredential credential) {
FirebaseAuth.getInstance().getCurrentUser().linkWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
//link auth success update ui
} else {
//link auth failed update ui
}
}
});
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user_phone_verify);
//init view
//get phone number
String phoneNumb = "Add Your Phone Number Here"
sendVerificationCode(phoneNumb)
//if mCallback not called,
//use this button to sign in with manual input verification code
btnSignIn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//get verification id from mCallback.onCodeSent
//get verificationCode manually from edittext
PhoneAuthCredential credential = PhoneAuthProvider.getCredential(verificationId, verificationCode);
linkPhoneAuthToCurrentUser(credential);
}
});
}
PS : you need to re-authenticate your email authentication before link phone number authentication.
Follow this link to re-authenticate
