创建签名的 APK 后，Firebase 电话身份验证不起作用

Question

我的应用程序工作正常，直到我在 Android Studio 中生成一个签名的 APK，当我对签名的 Apk 进行身份验证时，它只显示一个 Toast“无法验证手机并创建帐户”。它在调试模式下运行良好。当我制作调试 APK 时，它在其中也运行良好，但在签名 APK 中运行良好。我无法弄清楚是什么导致了身份验证在签名 APK 中不起作用

我的代码

   public class Register2 extends AppCompatActivity {

    FirebaseAuth auth;
    DatabaseReference reference;

    String otpCode;
    String verificationId;
    MaterialEditText phone, optEnter;
    Button next;

    PhoneAuthCredential credential;
    Boolean verificationOnProgress = false;
    ProgressBar progressBar;
    TextView resend;

    PhoneAuthProvider.ForceResendingToken token;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_register2);

        phone = findViewById(R.id.phone);
        optEnter = findViewById(R.id.codeEnter);
        countryCodePicker = findViewById(R.id.ccp);
        next = findViewById(R.id.nextBtn);
        auth = FirebaseAuth.getInstance();
        progressBar = findViewById(R.id.progressBar);
        resend = findViewById(R.id.resendOtpBtn);

        resend.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // todo:: resend OTP

                        next.setEnabled(false);
                        String phoneNum = "+" + countryCodePicker.getSelectedCountryCode() + phone.getText().toString();
                        Log.d("phone", "Phone No.: " + phoneNum);

Answer 1

将应用程序上传到 Google Play 商店后，您必须在 Firebase 中更新 SHA-1/SHA-255 指纹。您可以在 Play 商店中找到给定的 SHA-1/SHA-255。

1. 导航到 Google Play 控制台并登录
2. 选择您要签名的应用程序
3. 转到版本管理 > 应用签名
4. 从应用签名证书部分复制/下载 SHA-1 或 SHA-256 证书指纹

现在，将 SHA-1/SHA-255 添加到 Firebase，您的应用将再次返回。

您是否添加了您的应用SHA-1 Fingerprint in Firebase Console，如果没有，请关注此link。
