Firebase 电话身份验证在调试模式下工作正常，但应用程序在发布时崩溃

Question

是因为权限吗？

我在运行时授予了READ_SMS , RECEIVE_SMS, READ_PHONE_STATE 权限，但它仍然崩溃。

还需要做什么？

更新

在 Openning_Screen.java

中

private void attemptsRegistration() {

    Intent intent = new Intent(Opening_Screen.this,PhoneVerification.class);
    intent.putExtra(Constant.REQUEST_CODE,55);
    startActivityForResult(intent,55);
}

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        final View view = findViewById(android.R.id.content);
        if (requestCode == 55){
            String result = data.getStringExtra("result");
            if (result.equals("PhoneVerifiedSuccessfully")){
                RegistrationDataPass.setPhone(data.getStringExtra("phone"));
                Intent i = new Intent(Opening_Screen.this,RegPage1.class);
                i.putExtra("PhoneNumber",data.getStringExtra("phone"));
                startActivity(i);
            }else if (result.equals("InvalidCode")){
                Constant.showSnak(view,"Registration Failed\nInvalid Code");
            }else if (result.equals("INVALID REQUEST")){
                Constant.showSnak(view,"Registration Failed\nINVALID REQUEST");
            }else if (result.equals("Too many Request")){
                Constant.showSnak(view,"Registration Failed\nToo many Requests");
            }
        }
}

Phone_Verification.java 代码很大，我正在解释它是如何工作的。 当它开始时，我正在检查 ma​​rshmallow 的权限，然后在授予所有权限后，电话号码将作为用户的输入，然后转到 verifyPhone()

public void verifyPhone(String phn, PhoneAuthProvider.OnVerificationStateChangedCallbacks _mCallbacks){
    mCallbacksResend = _mCallbacks;
    Constant.showProgressBar(this,"You will receive an OTP in "+phn);
    Log.e("STEP Inside ver pn",phn);
    PhoneAuthProvider.getInstance().verifyPhoneNumber(
            phn,        // Phone number to verify
            60,                 // Timeout duration
            TimeUnit.SECONDS,   // Unit of timeout
            this,               // Activity (for callback binding)
            _mCallbacks);        // OnVerificationStateChangedCallback
}

而验证回调是这样的

final PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallBacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
        @Override
        public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
            //progressDialog.dismiss();
            Log.d("JEJE", "onVerificationCompleted:" + phoneAuthCredential);
            Log.e("STEP in signin","InsideVerification");
            signInWithPhoneAuthCredential(phoneAuthCredential);
        }

        @Override
        public void onVerificationFailed(FirebaseException e) {
            Constant.hideProgressBar();
            Log.w("JEJE", "onVerificationFailed", e);
            if (e instanceof FirebaseAuthInvalidCredentialsException) {
                Log.d("JEJE", "INVALID REQUEST");
                Intent intent = new Intent();
                intent.putExtra("result","INVALID REQUEST");
                intent.putExtra("phone",phoneNumber);
                setResult(REQ_CODE,intent);
            } else if (e instanceof FirebaseTooManyRequestsException) {
                Log.d("JEJE", "Too many Request");
                Intent intent = new Intent();
                intent.putExtra("result","Too many Request");
                intent.putExtra("phone",phoneNumber);
                setResult(REQ_CODE,intent);
            }
            showSnakBar(e.toString());
            //hideProgressDialog();
            Constant.hideProgressBar();
            Toast.makeText(PhoneVerification.this, "Failed", Toast.LENGTH_SHORT).show();
            finish();
        }
        @Override
        public void onCodeSent(String s, PhoneAuthProvider.ForceResendingToken forceResendingToken) {
            super.onCodeSent(s, forceResendingToken);
            //hideProgressDialog();
            Constant.hideProgressBar();
            Log.d("JEJE", "onCodeSent:" + s);
            mResendToken = forceResendingToken;
            tv.setText("We have sent a verification Code to your number "+phoneNumber+" via SMS.\nEnter the CODE bellow");
            phoneNumLayout.setVisibility(View.GONE);
            otpLayout.setVisibility(View.VISIBLE);
            verifyToken = s;
            showTimer();
        }
    };

在verifyPhone() 中显示进度条后应用程序崩溃。未发送任何代码。

Answer 1

IMO 你必须将正确的key,value 对传递给intent.puExtra() 试试下面的代码

intent.putExtra("result",55);

那么你的data.getStringExtra("result"); 获得价值

 if (requestCode == 55){
            String result = data.getStringExtra("result");

或试试下面的代码，这可能会有所帮助

Intent intent = new Intent(Opening_Screen.this,PhoneVerification.class);
intent.putExtra(Constant.REQUEST_CODE,55);
intent.putExtra("result",YOUR_RESULT_STRING);
intent.putExtra("phone",PHONE_STRING);
startActivityForResult(intent,55);

Answer 2

在添加@Omi 的答案后，这是您需要添加的另一个条件。

if (requestCode == 55 && data!=null){
  //here your code
}

希望得到帮助。

Answer 3

转到设置->开发者选项->应用程序部分& 确保您的“不保留活动”选项处于关闭状态，然后尝试

Answer 4

嗯，问题已经解决了。

我对问题的理解是错误的。问题不是因为Android版本。每个版本都会出现问题。

原因

正如我所描述的，该应用程序在调试模式下工作正常，但在发布模式下不工作。我使用了 Firebase 电话身份验证。并且需要SHA certificate fingerprints。不幸的是，我忘记提供版本 SHA-1。我在发布版本中使用了调试 SHA-1 指纹。

解决方案

提供了发布版 SHA-1 指纹。
