我正在尝试构建一个 firebase 登录功能，但即使捕获了抛出的异常，代码也会崩溃。
当我将异常作为日志输出时，代码可以工作，但是当我将其作为异常传递时，它会崩溃。
我想将异常传递给 MainActivity 以便在那里正确处理它，即在那里将 exception.message 作为 toast 输出。
只有当 firebase 报告崩溃异常时，登录过程才能使用有效的登录数据而不会出现问题。
internal var loginResult = MutableLiveData<LoginResult>()
inner class LoginResult {
var authResult: AuthResult? = null
var exception: Exception? = null
var isSuccessful = false
constructor(authResult: AuthResult?, isSuccessful: Boolean) {
this.authResult = authResult
this.isSuccessful = isSuccessful
}
constructor(authResult: AuthResult?, exception: Exception?, isSuccessful: Boolean) {
this.authResult = authResult
this.exception = exception
this.isSuccessful = isSuccessful
}
}
fun login(context: Context, email: String, password: String) {
FirebaseAuth.getInstance().signInWithEmailAndPassword(email, password)
.addOnCompleteListener { task ->
if (task.isSuccessful) {
loginResult.value = LoginResult(task.result, task.isSuccessful)
startSession(context, LoginType.CREDENTIAL)
saveCredentialsEncrypted(context, email, password)
} else {
try {
loginResult.value = LoginResult(task.result, task.exception, task.isSuccessful)
} catch (e: FirebaseAuthInvalidCredentialsException) {
loginResult.value = LoginResult(task.result, e, task.isSuccessful)
} catch (e: Exception) {
loginResult.value = LoginResult(task.result, e, task.isSuccessful)
}
}
}
}

更新： 抛出错误是因为我尝试访问 task.result，但没有结果，请参阅 try catch 块。
为了解决这个错误，我传递了 null 作为 authResult
fun login(context: Context, email: String, password: String) {
FirebaseAuth.getInstance().signInWithEmailAndPassword(email, password)
.addOnCompleteListener { task ->
if (task.isSuccessful) {
loginResult.value = LoginResult(task.result, task.isSuccessful)
startSession(context, LoginType.CREDENTIAL)
saveCredentialsEncrypted(context, email, password)
} else {
loginResult.value = LoginResult(null, task.exception, task.isSuccessful)
}
}
}
