java - 存在 URI 问题的用户注册

Question

所以这对我来说是一个很难问的问题，因为我不清楚这个问题。 logcat 只是快速地吐出一行又一行的错误，但没有明确解释错误所在。

我一直在尝试做到这一点，以便当用户注册时，默认头像会添加到他们的帐户中，但由于某种原因，当我向帐户添加默认 URI 时，注册失败。应用不会崩溃，并且帐户已创建，但用户未正确添加到我的 Firebase 数据库中，并且没有向用户发送身份验证电子邮件。

因此，为了创建此默认头像，我已将图像上传到 Firebase 存储，并通过执行此操作将图像的 URL 转换为 URI

public Uri defaultAvatar = Uri.parse("https://firebasestorage.googleapis.com/v0/b/fifty-fifty-1314c.appspot.com/o/defaultavatarmale.png?alt=media&token=def5ee33-6664-4344-bfca-27e4b284df00");

然后，当用户点击注册时，他们的帐户就会被创建，并且应该使用此行添加到数据库中

User users = new User(username, email, defaultAvatar, wins, losses, balance, null, 0, false);

每当显示 defaultAvatar 的位置为 null 时，帐户注册都会正常工作，但每当我将其更改为该 URI 时，它就会崩溃。这就是注册用户的整个方法

    firebaseAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {
            if (task.isSuccessful()) {
                sendVerificationEmail();
                //start profile activity here

                User users = new User(username, email, defaultAvatar, wins, losses, balance, null, 0, false);
                FirebaseDatabase.getInstance().getReference("Users")
                        .child(FirebaseAuth.getInstance().getCurrentUser().getUid())
                        .setValue(users)
                        .addOnCompleteListener
                                (new OnCompleteListener<Void>() {
                    @Override
                    public void onComplete(@NonNull Task<Void> task) {
                        if (task.isSuccessful()) {
                            firebaseUser = FirebaseAuth.getInstance().getCurrentUser();
                                        Toast.makeText(RegisterActivity.this, "A verification link has been sent to your email.", Toast.LENGTH_SHORT).show();
                                        startActivity(new Intent(RegisterActivity.this, LoginActivity.class));
                                        overridePendingTransition(R.anim.slide_left, R.anim.slide_right);
                                } else {
                                    Toast.makeText(RegisterActivity.this, task.getException().getMessage(), Toast.LENGTH_SHORT).show();
                                    progressDialog.hide();
                                }
                            }
                        });
            } else {
                Toast.makeText(RegisterActivity.this, "Registration not successful, please try again.", Toast.LENGTH_SHORT).show();
                progressDialog.hide();
            }
        }
    });

给我一​​个错误的行是:

.setValue(users)

我的 logcat 应该可以帮助我解决这种情况，但每当有人尝试注册时，它就会变得一团糟。我尝试过滤其中的内容以查找特定错误，但似乎没有任何效果。 Logcat 中有太多内容，顶部的行立即开始消失，所以我看不到最初的错误。如果有人可以帮助我缩小 logcat 中的问题范围，我也将不胜感激!

我会显示我的 logcat 所说的内容，但我认为它目前没有任何用处

Answer 1

实时数据库 SDK 不能很好地处理 Uri 对象。它试图对其所有 getter 方法公开的所有数据执行复杂的序列化。相反，您应该将头像字段的类型指定为字符串，因为这就是您真正想要存储的所有内容。或者，或者创建您想要序列化的所有字段的映射，并确保它们具有您想要为用户存储的简单数据类型。
