我正在使用电子邮件/密码和电话方法注册用户。
申请程序如下
使用PhoneAuthCredential登录用户>使用输入的电子邮件和密码通过EmailCredential链接创建的用户>发送电子邮件验证>数据库条目
public class Sign_Up_page extends AppCompatActivity {
private String TAG = "Sign_Up_page";
// UI Widgets.

super.onStart();
firebaseAuth.addAuthStateListener(authListener);
}
@Override
protected void onStop() {
super.onStop();
firebaseAuth.addAuthStateListener(authListener);
}
}
现在问题出在10次尝试中就有1次 firebaseAuth.getCurrentUser（）与电子邮件凭据链接后变为空
我添加了authStateListener来跟踪用户身份验证状态中的更改
这是屏幕截图
of steps
这是我的 users 表
的数据库写入规则
"users":{
"$uid":{
".write": "auth.uid != null && newData.exists()",
},
".indexOn": "role"
}
现在我可以处理空用户或数据库故障，但是我想知道并防止导致此问题的原因
我做错了什么，或者这是一个firebase错误...？
