OTP 没有从 firebase 代码中获取是正确的

Question

我想从 Firebase 获取 OTP 到我的手机以进行验证，我已经按照文档所述完成了所有操作，但最后我没有得到 OTP 请帮助我，我知道我的代码有问题，任何人都可以纠正我吗？我的应用程序已连接并使用 firebase 这是我的活动 java 代码：

public class LoginActivity extends AppCompatActivity {

String phone_number;

FirebaseAuth auth;

PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks;

@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_login);

    mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks(){

        @Override

        public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {

        }

        @Override

        public void onVerificationFailed(FirebaseException e) {

        }

    };

    CardView card_view = findViewById(R.id.cardView);

    card_view.setOnClickListener(new View.OnClickListener() {

        @Override

        public void onClick(View v) {

            EditText phonetextview = findViewById(R.id.phonetextview);

            phone_number = PhoneNumberUtils.formatNumber(phonetextview.getText().toString());

            send();

            Toast toast = Toast.makeText(getApplicationContext(), phone_number,

                    Toast.LENGTH_SHORT);

            toast.show();

        }

    });

}

private void send() {

    PhoneAuthProvider.getInstance().verifyPhoneNumber(

            phone_number,        // Phone number to verify

            60,                 // Timeout duration

            TimeUnit.SECONDS,   // Unit of timeout

            this,               // Activity (for callback binding)

            mCallbacks);             // ForceResendingToken from callbacks

    }

}

您需要intialize firebase在使用它之前。为此创建一个Application类 .ie ：public class MyApplication extends Application {&nbsp; &nbsp; @Override&nbsp; &nbsp; public void onCreate() {&nbsp; &nbsp; &nbsp; &nbsp; super.onCreate();&nbsp; &nbsp; &nbsp; &nbsp; FirebaseApp.initializeApp(this);//here we are intializing firebase&nbsp; &nbsp; }}也不要忘记将此添加到您的AndroidManifest.xml：<application&nbsp; &nbsp; &nbsp; &nbsp; android:name="yourPackage.MyApplication"&nbsp; &nbsp; &nbsp; &nbsp; android:allowBackup="true"&nbsp; &nbsp; &nbsp; &nbsp; android:icon="@mipmap/route"&nbsp; &nbsp; &nbsp; &nbsp; android:theme="@style/AppTheme">&nbsp;<!--your activity classes-->&nbsp; <activity&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:name=".YourActivity"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; >&nbsp;</application>

确保您不在模拟器上，然后确保您已将有效的 SHA-1 密钥添加到 Firebase 控制台。试试这个来检查你得到了什么错误&nbsp;&nbsp;&nbsp;&nbsp;@Override&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;public&nbsp;void&nbsp;onVerificationFailed(FirebaseException&nbsp;e)&nbsp;{&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.printStackTrace();&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}
