如何使用 java android 在 firebase 中发送 otp 代码短信？

Question

I have a Android Studio project with firebase, I already implement firebase correctly.

im trying to make a sign in with sms authentication, everything works but no sms arrives

I already configure firebase authentication

here's some code

mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
                @Override
                public void onVerificationCompleted(PhoneAuthCredential credential) {
                    Toast.makeText(MainActivity.this, "Verification Complete", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onVerificationFailed(FirebaseException e) {
                    Toast.makeText(MainActivity.this, "Verification Failed", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onCodeSent(String verificationId,
                                       PhoneAuthProvider.ForceResendingToken token) {
                    Toast.makeText(MainActivity.this, "Code Sent", Toast.LENGTH_SHORT).show();
                }
            };

@Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.bt_send_otp:

                PhoneAuthProvider.getInstance().verifyPhoneNumber(
                        etPhone.getText().toString(),        // Phone number to verify
                        1,                 // Timeout duration
                        TimeUnit.MINUTES,   // Unit of timeout
                        this,               // Activity (for callback binding)
                        mCallbacks);        // OnVerificationStateChangedCallbacks

                break;
            case R.id.bt_resend_otp:
                break;
            case R.id.bt_verify_otp:
                break;
        }
   }

when I press the send otp button the toast "Code Sent" appears

Thanks for the help:)

Since it is a test number, OTP will not arrive. Though for testing you can use the verification code you added with the test phone number on the console. Firebase Console Dashboard -> Authentication -> SignIn Method -> Phone -> Phone numbers for testing .

Check out the docs for Firebase Phone Verification for Android : https://firebase.google.com/docs/auth/android/phone-auth?authuser=1#test-with-whitelisted-phone-numbers
