firebase phone auth android崩溃 _firebase

将相本无种，男儿当自强。这篇文章主要讲述firebase phone auth android崩溃相关的知识，希望能为你提供帮助。
【firebase phone auth android崩溃】所以我正在使用firebase数据库和Auth，我正在尝试构建Phone Auth但由于某种原因应用程序崩溃..不知道为什么..我是新的编程与android工作室和Firebase数据库上的第一个计时器，不知道为什么应用程序崩溃，但它崩溃后，我按下一个激活verifySignInCode（）insta崩溃的按钮后，它确实发送一个代码为电子邮件的邮件错误在这里

09-15 20:39:41.804 22046-22046/com.example.erelpc.calltest E/AndroidRuntime: FATAL EXCEPTION: main Process: com.example.erelpc.calltest, PID: 22046 java.lang.IllegalArgumentException: Cannot create PhoneAuthCredential without either verificationProof, sessionInfo, ortemprary proof. at com.google.android.gms.common.internal.Preconditions.checkArgument(Unknown Source:8) at com.google.firebase.auth.PhoneAuthCredential.< init> (Unknown Source:6) at com.google.firebase.auth.PhoneAuthProvider.getCredential(Unknown Source:33) at com.example.erelpc.calltest.MainActivity.verifySignInCode(MainActivity.java:92) at com.example.erelpc.calltest.MainActivity.access$100(MainActivity.java:28) at com.example.erelpc.calltest.MainActivity$2.onClick(MainActivity.java:61) at android.view.View.performClick(View.java:6877)

这是MainActivity

/// SMS Handler private void sendVerificationCode(){ String phone = etphonenumber.getText().toString(); if (phone.isEmpty()) { etphonenumber.setError("Enter a Phone Number!"); etphonenumber.requestFocus(); return; } if (phone.length() != 9){ etphonenumber.setError("Please Enter a valid Number!"); etphonenumber.requestFocus(); return; } phone = "+972" + phone; Intent intent =new Intent(this, loginsuccess.class); PhoneAuthProvider.getInstance().verifyPhoneNumber( phone,// Phone number to verify 60,// Timeout duration TimeUnit.SECONDS,// Unit of timeout this,// Activity (for callback binding) mCallbacks); // OnVerificationStateChangedCallbacks } private void verifySignInCode(){String code = etcodeveri.getText().toString(); PhoneAuthCredential credential = PhoneAuthProvider.getCredential(codesent, code); signInWithPhoneAuthCredential(credential); }PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() { @Override public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {}@Override public void onVerificationFailed(FirebaseException e) {}@Override public void onCodeSent(String s, PhoneAuthProvider.ForceResendingToken forceResendingToken) { super.onCodeSent(s, forceResendingToken); codesent = s; } }; private void signInWithPhoneAuthCredential(PhoneAuthCredential credential) { mAuth.signInWithCredential(credential) .addOnCompleteListener(this, new OnCompleteListener< AuthResult> () { @Override public void onComplete(@NonNull Task< AuthResult> task) { if (task.isSuccessful()) { Toast.makeText(getApplicationContext(), "Login Success!", Toast.LENGTH_SHORT).show(); registerModule(); } else { if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) { Toast.makeText(getApplicationContext(), "Login Unsuccess!", Toast.LENGTH_SHORT).show(); } } } }); } public void registerModule(){ Intent intent =new Intent(this, loginsuccess.class); startActivity(intent); }

按下“btnAdd”后发生崩溃
答案该应用程序崩溃，因为该方法没有获得有效的credential使phoneAuth工作。这可以通过在try方法上使用catch和signInWithPhoneAuthCredential()来解决。
在代码中它看起来像这样：

private void verifyCode(){String code = cd.getText().toString(); // this is OTP String pH = phone.getText().toString(); // this is phone number if(code.equals("") & & pH.equals("")) Toast.makeText(MainActivity.this,"Nothing to validate", Toast.LENGTH_SHORT).show(); else { try { PhoneAuthCredential credential = PhoneAuthProvider.getCredential(otp, code); signInWithPhoneAuthCredential(credential); } catch (Exception e) { Log.i("exception",e.toString()); Toast.makeText(MainActivity.this,"Invalid credentials",Toast.LENGTH_LONG).show(); }} }

此外，你应该放置更多的catch或if语句，以避免在方法中给出null值。
