OTP无法通过Firebase恢复

Question

我正确地编写了代码，但是无法将otp移至移动设备。我所做的是，从我将手机号码传递到第二个活动后的第一次活动，它的运行就像一种魅力。 onVerificationFailed中的Toast正在工作（如果我输入了手机号码以外的其他号码），我有sh-1键，我没有将号码保存在Firebase中，我检查了这些内容。

这些是依赖项

dependencies {
    classpath 'com.android.tools.build:gradle:3.3.1'
    classpath 'com.google.gms:google-services:4.0.0'

这是我验证otp的活动代码

public class VerifyPhoneActivity extends AppCompatActivity {

//These are the objects needed
//It is the verification id that will be sent to the user
private String mVerificationId;

//The edittext to input the code
private EditText editTextCode;

//firebase auth object
private FirebaseAuth mAuth;
String   code;
String mobile;
String codesent;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_verify_phone);

    mAuth= FirebaseAuth.getInstance();

    sendVerificationCode();




    findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {




            verifySignInCode();





        }
    });



}

private void verifySignInCode()


    {

        EditText fd = (EditText) findViewById(R.id.et1);
        String value= fd.getText().toString();
      //        int finalValue=Integer.parseInt(value);

        final EditText sd = (EditText) findViewById(R.id.et2);
        String value1= sd.getText().toString();
        // int finalValue1=Integer.parseInt(value1);

        EditText td = (EditText) findViewById(R.id.et3);
        String value2= td.getText().toString();
        // int finalValue2=Integer.parseInt(value2);

        EditText fod = (EditText) findViewById(R.id.et4);
        String value3= fod.getText().toString();
        //int finalValue3=Integer.parseInt(value3);

        EditText fid = (EditText) findViewById(R.id.et5);
        String value4= fid.getText().toString();
        //int finalValue4=Integer.parseInt(value4);

        EditText sid = (EditText) findViewById(R.id.et6);
        String value5= sid.getText().toString();
        //int finalValue5=Integer.parseInt(value5);

        code = value + value1+value2+value3+value4+value5;

        PhoneAuthCredential credential = PhoneAuthProvider.getCredential(codesent, code);
        signInWithPhoneAuthCredential(credential);


    }

private void signInWithPhoneAuthCredential(PhoneAuthCredential credential) {
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                        // Sign in success, update UI with the signed-in user's information
                      //  Log.d(TAG, "signInWithCredential:success");

                       // FirebaseUser user = task.getResult().getUser();
                        // ...
                    } else {
                        // Sign in failed, display a message and update the UI
                       // Log.w(TAG, "signInWithCredential:failure", task.getException());
                        if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) {
                            // The verification code entered was invalid
                        }
                    }
                }
            });
}

private void sendVerificationCode() {


    Intent intent = getIntent();
    mobile = intent.getStringExtra("mobile");

    String phonenumber= "+91"+mobile;

    Toast.makeText(getApplicationContext(), phonenumber,
            Toast.LENGTH_LONG).show();

   PhoneAuthProvider.getInstance().verifyPhoneNumber(

            phonenumber,        // Phone number to verify
            60,                 // Timeout duration
            TimeUnit.SECONDS,   // Unit of timeout
            this,               // Activity (for callback binding)
            mCallbacks);        // OnVerificationStateChangedCallbacks





}
PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks=new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
    @Override
    public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {

    }

    @Override
    public void onVerificationFailed(FirebaseException e) {

        Toast.makeText(getApplicationContext(), "faild",
                Toast.LENGTH_LONG).show();
    }

    @Override
    public void onCodeSent(String s, PhoneAuthProvider.ForceResendingToken forceResendingToken) {
       // super.onCodeSent(s, forceResendingToken);


        Toast.makeText(getApplicationContext(), "sent",
                Toast.LENGTH_LONG).show();
        codesent=s;

    }
};

}

我认为问题出在这里。

 PhoneAuthProvider.getInstance().verifyPhoneNumber(

            phonenumber,        // Phone number to verify
            60,                 // Timeout duration
            TimeUnit.SECONDS,   // Unit of timeout
            this,               // Activity (for callback binding)
            mCallbacks);        // OnVerificationStateChangedCallbacks


}

我刚开始使用Android。
