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'

sendVerificationCode(phoneNumb)
//if mCallback not called,
//use this button to sign in with manual input verification code
btnSignIn.setOnClickListener(new View.OnClickListener() {

//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 https://firebase.google.com/docs/auth/android/manage-users#re-authenticate_a_user
onVerificationCompleted is called when firebase automatically verifies the phone number by detecting the sms code sent to the phone.
I think you should reformat your code to either use only the credential here, or the one you generate manually by combination of the code entered by the user and verificationId; and not both.
Also no need to sign in again with phone credential, you already signed in
I mean you should have something like this instead,
private void linkWithCredential(final PhoneAuthCredential credential) {
mAuth.getCurrentUser().linkWithCredential(credential).addOnComplete.......{
onComplete(....) {
.....
//signInWithPhoneCredential(credential);
// You Already signed in. No need. Just update the ui with the user info
}

I want to verify user through phone number verification OTP code, now I am unable to fix this issue. I am new in android App development. I have connected Firebase with android studio, that's all fine except this error.
(Activity) TaskExecutors.MAIN_THREAD line is wrong. It's clear from the error message that the cast cannot be made.
Since you're in activity, just this should do it in this place.
Just Replace: (Activity) TaskExecutors.MAIN_THREAD,

did you add at AndroidManifest.xml these permissions ?
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.READ_SMS"/>
i think because your code is missing premission check function that's why send you to navigation add this code to your code in VerifyOTP.java
private void checkForSmsPermission() {
if (ActivityCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS) !=
PackageManager.PERMISSION_GRANTED) {
Log.d(TAG, getString(R.string.permission_not_granted));
// Permission not yet granted. Use requestPermissions().
// MY_PERMISSIONS_REQUEST_SEND_SMS is an
// app-defined int constant. The callback method gets the
// result of the request.
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
} else {
// Permission already granted. Enable the SMS button.
enableSmsButton();
}
}
Add these dependencies in your build.gradle :
implementation "androidx.browser:browser:1.3.0"
implementation "com.google.firebase:firebase-messaging:21.1.0"
Firebase Quote "The reCAPTCHA flow will only be triggered when SafetyNet is unavailable or your device does not pass suspicion checks. Nonetheless, you should ensure that both scenarios are working correctly." So to enable SafetyNet, follow the below steps or you can also visit Firebase Auth for more info.
Go to google cloud console, select your project.
Click on the navigation menu and select APis & services and then select Dashboard.
Click on enable api and services and enable api " Android Device Verification".
Add SHA 256 in firebase project settings.(debug and release both)
Download and replace the latest google-services.json file in your project.
I'm trying to authenticate user with phone number using the firebase Authentication method. But it is showing me error after some time by running the code. And I think the sendVerificationCodeToUser() function is not working properly.

I am trying to set up OTP verification
I have already tried many possibilities with the if and else, however, it didn't help out.
public class userLogin extends Activity {
EditText phnNum=null, veri = null;
FirebaseAuth au;
Button forgotpass, login;
PhoneAuthProvider.OnVerificationStateChangedCallbacks otp;
String verifyCode;
#Override

super.onCreate(savedInstanceState);

forgotpass = findViewById(R.id.forgot_pass);
au = FirebaseAuth.getInstance();
login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if ((phnNum.getText().toString()).equals("")) {
(Toast.makeText(getApplicationContext(), "Please enter the phone number and proceed to receive an OTP", Toast.LENGTH_SHORT)).show();
}
else{
otp = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
#Override
public void onVerificationCompleted(#NonNull PhoneAuthCredential phoneAuthCredential) {
}
#Override
public void onVerificationFailed(#NonNull FirebaseException e) {
}
#Override
public void onCodeSent(#NonNull String s, #NonNull PhoneAuthProvider.ForceResendingToken forceResendingToken) {
super.onCodeSent(s, forceResendingToken);
verifyCode = s;
(Toast.makeText(getApplicationContext(), "The OTP Code has been send, please verify the code", Toast.LENGTH_SHORT)).show();
}
};
}
}
});
}
public void send_sms (View v){
String i = (phnNum.getText()).toString();
PhoneAuthProvider.getInstance().verifyPhoneNumber(i, 60, TimeUnit.SECONDS, this, otp);
login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent u = new Intent(view.getContext(), otp_verify.class);
startActivity(u);
}
});
}
//SignIn Method
// We will pass value in the method with "PhoneAuthCredential" data-type.
public void SignIn(PhoneAuthCredential credential) {
//" au " is the firebase variable and call the method
au.signInWithCredential(credential).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
(Toast.makeText(getApplicationContext(), "You have Sign-In Successfully", Toast.LENGTH_SHORT)).show();
}
else{
(Toast.makeText(getApplicationContext(), "Please try again", Toast.LENGTH_SHORT)).show();
}
}
});
}
}
When I log-in with blank EditText, the if part executes but when I enter the phone number it doesn't execute the else part. I expect the when the user enters their phone number the else part should execute.
final String i = (phnNum.getText()).toString();
if ("".equals(i)) {
(Toast.makeText(getApplicationContext(), "Please enter the phone number and proceed to receive an OTP", Toast.LENGTH_SHORT)).show();
} else {
// 1. prepare callback for async call
otp = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
#Override
public void onVerificationCompleted(#NonNull PhoneAuthCredential phoneAuthCredential) {
}
#Override
public void onVerificationFailed(#NonNull FirebaseException e) {
}
#Override
public void onCodeSent(#NonNull String s, #NonNull PhoneAuthProvider.ForceResendingToken forceResendingToken) {
super.onCodeSent(s, forceResendingToken);
verifyCode = s;
(Toast.makeText(getApplicationContext(), "The OTP Code has been send, please verify the code", Toast.LENGTH_SHORT)).show();
Intent u = new Intent(userLogin.this, otp_verify.class);
startActivity(u);
}
};
// 2. execute actual call
PhoneAuthProvider.getInstance().verifyPhoneNumber(i, 60, TimeUnit.SECONDS, userLogin.this, otp);
}
The code snippet prepares callback and uses it on Firebase auth call. When the verification code is actually sent, the onCodeSent called and new activity launched.
so I am using firebase database and Auth, I am trying to build Phone Auth but for some reason the app is crashing.. not sure why..
I am new to programming with android studio and first timer on Firebase database, not sure why the app is crashing but its crashing after I am pressing a button that activate verifySignInCode() insta crash after it, it does send an email with code a

The crashing is happening after I press the "btnAdd"
The app is crashing because the method is not getting valid credential for the phoneAuth to work. This can be fixed by using try and catch on the signInWithPhoneAuthCredential() method.
In code it will look something like this:
private void verifyCode(){
String code = cd.getText().toString(); // this is OTP
String pH = phone.getText().toString(); // this is phone number
if(code.equals("") && pH.equals(""))
Toast.makeText(MainActivity.this,"Nothing to validate", Toast.LENGTH_SHORT).show();
else {
try {
PhoneAuthCredential credential = PhoneAuthProvider.getCredential(otp, code);
signInWithPhoneAuthCredential(credential);
}
catch (Exception e) {
Log.i("exception",e.toString());
Toast.makeText(MainActivity.this,"Invalid credentials",Toast.LENGTH_LONG).show();
}
}
}
Also, you should put more catch or if statements to avoid giving null value in the methods.
Just need to define String code before calling phoneAuth function.
< String code = phoneAuthCredential.getSmsCode();
assert code != null;
PhoneAuthCredential credential = PhoneAuthProvider.getCredential(mVerificationId, code);
signInWithPhoneAuthCredential(credential);>
