Java 用户注册与URI问题
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,没有清楚地解释什么是错误的 我一直试图做到这一点,当用户注册时,默认的化身被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。应用程序不会崩溃,并且已创建帐户,但用户未正确添加到我的Firebase数据库,并且未向用户发送身份验证电子邮件 因此,为了创建这个默认的化身,我将一个图像上传到我的Firebase存储中,并通过这样做将图像的URL转换为URIJava 用户注册与URI问题,java,android,firebase-realtime-database,firebase-authentication,Java,Android,Firebase Realtime Database,Firebase Authentication,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,没有清楚地解释什么是错误的 我一直试图做到这一点,当用户注册时,默认的化身被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。应用程序不会崩溃,并且已创建帐户,但用户未正确添加到我的Firebase数据库,并且未向用户发送身份验证电子邮件 因此,为了创建这个默认的化身,我将一个图像上传到我的Firebase存储中,并通过这样做将图像的URL转换为URI public 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register时,将创建他们的帐户,并使用此行将其添加到数据库中
User users = new User(username, email, defaultAvatar, wins, losses, balance, null, 0, false);
每当显示defaultAvatar的位置为空时,帐户注册就会完美地工作,但每当我将其更改为该URI时,它就会崩溃。这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();
}
}
});
在这种情况下,我的日志本应帮助我,但每当有人试图注册时,它就乱成一团。我试图过滤其中的内容,以找到特定的错误,但似乎没有任何效果。Logcat中包含了太多内容,顶部的行开始立即消失,所以我看不到初始错误。如果有人能帮我缩小我日志中的问题,我也会很感激
我想展示一下我的日志,但我认为目前它在任何方面都没有用处

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,您应该将化身字段的类型指定为一个字符串,因为这就是您真正想要存储的所有内容。要么这样做,要么创建所有要序列化的字段的映射,并确保它们具有要为用户存储的简单类型的数据。我认为尝试了解日志中的内容是值得的,因为如果没有错误消息,我们只能猜测。@DougStevenson我粘贴了日志的剪贴画,但是还有7000多行基本上只是snippit的重复。什么是你的用户类?@DougStevenson将其添加到postSo的底部。如果我将URI类型更改为字符串,并将URL存储为字符串,那么要将化身显示为图像,我是否应该将其转换回图像显示的URI?这样行吗?是的,如果你需要一个Uri,就转换它。
