当我单击按钮时，信息未保存到数据库

Question

我试图将在字段中输入的信息保存到数据库中，但是每次单击按钮时，应用程序仅运行进度对话框。它也不会带我进行下一个活动，也不会将我的输入信息保存到数据库中。怎么了？

我的班级代码：

extraData={[...checkins, ...orders, ...waitercalls]}

我的xml代码：

Answer 1

代替这个烤面包：

Toast.makeText(RegisterActivity.this, "Authentication failed.", Toast.LENGTH_SHORT).show();

使用此：

Toast.makeText(RegisterActivity.this, task.getException().getMessage(), Toast.LENGTH_LONG).show();

如果您想知道注册失败的原因。
原因可能是：用户已经使用相同的电子邮件，弱密码或...注册了。
