火碱手机身份验证安卓崩溃

Question

所以我正在使用Firebase数据库和身份验证，我正在尝试构建Phone Auth，但由于某种原因该应用程序崩溃..不知道为什么.. 我是使用 android 工作室和 Firebase 数据库的第一个计时器编程的新手，不确定为什么该应用程序崩溃，但在我按下激活 verifySignInCode(( insta 崩溃的按钮后它崩溃了，它确实发送了一封带有代码的电子邮件 日志猫错误在这里

这是主要活动

/// SMS Handler

String phone = etphonenumber.getText().toString();
if (phone.isEmpty()) {
etphonenumber.setError("Enter a Phone Number!");
etphonenumber.requestFocus();
return;

phone = "+972" + phone;
Intent intent =  new Intent(this, loginsuccess.class);

PhoneAuthCredential credential = PhoneAuthProvider.getCredential(codesent, code);
signInWithPhoneAuthCredential(credential);
}

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);
}

我按下"btnAdd"后崩溃

Answer 1

应用程序崩溃，因为该方法未获得有效credential以使phoneAuth正常工作。可以通过对signInWithPhoneAuthCredential()方法使用try和catch来解决此问题。

在代码中，它将如下所示：

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，您应该放置更多catch或if语句，以避免在方法中赋予null值。

只需要在调用 phoneAuth 函数之前定义字符串代码。

< String code = phoneAuthCredential.getSmsCode();
assert code != null;
PhoneAuthCredential credential = PhoneAuthProvider.getCredential(mVerificationId, code);
signInWithPhoneAuthCredential(credential);>
