【问题描述】：

我正在尝试验证电话号码，但始终失败。我有需要手机号码的登录活动。单击登录按钮后，我希望 OTP 活动将打开，用户可以在此处输入 OTP 并单击验证按钮以验证号码。但它总是继续 onVerificationFailed 块并显示 toast Verification Fail 和 Invalid Number。

登录活动

public class LoginMain extends AppCompatActivity {
public FirebaseAuth mAuth;
// [END declare_auth]

public String mVerificationId;
PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks;
public PhoneAuthProvider.ForceResendingToken mResendToken;

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

    final EditText txtMobileno = (EditText) findViewById(R.id.txtMobileno);
    Button btnLogin = (Button) findViewById(R.id.btnLogin);

    mAuth = FirebaseAuth.getInstance();

    mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
        @Override
        public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
            Toast.makeText(LoginMain.this, "Verification Done" + phoneAuthCredential, Toast.LENGTH_LONG).show();
        }

        @Override
        public void onVerificationFailed(FirebaseException e) {
            Toast.makeText(LoginMain.this, "Verification Fail", Toast.LENGTH_LONG).show();
            if (e instanceof FirebaseAuthInvalidCredentialsException) {
                Toast.makeText(LoginMain.this, "Invalid Number", Toast.LENGTH_SHORT).show();
            } else if (e instanceof FirebaseTooManyRequestsException) {
                Toast.makeText(LoginMain.this, "Too many Request", Toast.LENGTH_SHORT).show();
            }

        }

        @Override
        public void onCodeSent(String s, PhoneAuthProvider.ForceResendingToken forceResendingToken) {
            mVerificationId = s;
            mResendToken = forceResendingToken;
            Toast.makeText(LoginMain.this, "Code Sent", Toast.LENGTH_SHORT).show();
        }
    };

    txtMobileno.setText("+"+getCountrycode());

    btnLogin.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            String mobileno = txtMobileno.getText().toString();
            PhoneAuthProvider.getInstance().verifyPhoneNumber( mobileno, 60, TimeUnit.SECONDS, LoginMain.this, mCallbacks);
        }
    });
}

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 informatio
                        Toast.makeText(LoginMain.this, "Verification done", Toast.LENGTH_LONG).show();
                        FirebaseUser user = task.getResult().getUser();
                        // ...
                    } else {
                        // Sign in failed, display a message and update the UI
                        if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) {
                            // The verification code entered was invalid

                            Toast.makeText(LoginMain.this, "Verification failed code invalid", Toast.LENGTH_LONG).show();
                        }
                    }
                }
            });
}
}

OTP 活动

public class OTP extends AppCompatActivity {

public FirebaseAuth mAuth;
public String mVerificationId;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_otp);

    mAuth = FirebaseAuth.getInstance();

    Button btnVerify = (Button) findViewById(R.id.btnVerifyOTP);
    final EditText txtOtp = (EditText) findViewById(R.id.txtOtp);
    btnVerify.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            PhoneAuthCredential credential = PhoneAuthProvider.getCredential( mVerificationId  , txtOtp.getText().toString());
            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");
                        Toast.makeText(OTP.this,"Verification done",Toast.LENGTH_LONG).show();
                        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
                            Toast.makeText(OTP.this,"Verification failed code invalid",Toast.LENGTH_LONG).show();
                        }
                    }
                }
            });
}
}

错误：

[FirebaseAuth: ] getGoogleApiForMethod() 返回 Gms

【问题讨论】：

你能告诉我们错误日志吗？？
没有错误。
检查编辑后的答案
它正在进行 onVerificationFailed 意味着它正在调用firebase，但我猜有些东西丢失了。我不知道它是什么。
哦验证 SHA1 密钥和生成的 json 文件是否有效。如果不是其中任何一个，这可能是唯一的原因

【解决方案1】：

验证失败或号码无效通常发生在您发送的电话号码格式无效或您可能错过了正确的 google_service.json 文件时。

一种简单的格式包括发送带有正确国家代码的电话号码。请添加代码并发送。希望这有效。
