Question

我在这段代码中有一个问题，为什么每次在填写表格和ID后显示注册错误都可以，但是我不知道这段代码有什么问题，错误在这里！我该如何解决。请帮助我！谢谢

public class reg2activity extends AppCompatActivity {
EditText emailvariable;
EditText passvariable;
Button regvariable;
FirebaseAuth firebaseAuth;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_reg2activity);
    firebaseAuth=FirebaseAuth.getInstance();
    emailvariable=(EditText)findViewById(R.id.regemailid);
    passvariable=(EditText)findViewById(R.id.regpassid);
    regvariable=(Button)findViewById(R.id.Regloginid);
    regvariable.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            userReg();
        }
    });
}

public void userReg() {
    String emailstring=emailvariable.getText().toString();
    String passstring=passvariable.getText().toString();
    firebaseAuth.createUserWithEmailAndPassword(emailstring,passstring).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {
            if(task.isSuccessful())
            {
                Toast.makeText(reg2activity.this,"Regestration successful",Toast.LENGTH_LONG).show();
            }
            else
            {
                Toast.makeText(reg2activity.this,"Regestration error",Toast.LENGTH_LONG).show();
            }
        }
    });

我收到的错误消息是：

Answer 1

可以有多个reasons。

在您的AndroidManifest.xml中添加INTERNET，ACCESS_NETWORK_STATE，ACCESS_WIFI_STATE的权限。
当Google Play服务未运行时，也会发生这种情况。尝试启动Play商店并检查其是否正常运行。如果没有重启设备问题。并且还比较了项目中使用的Google Play服务和设备中的Google Play服务，如果未更新Google Play服务则相同。这只是一个很小但可能的情况，它会给出异常。

Answer 2

常见问题可能是

首先：未启用身份验证

Enable Email/Password sign-in:
 a. In the Firebase console, open the Auth section.
 b. On the Sign in method tab, enable the Email/password sign-in method and click Save.

第二个：电子邮件无效或密码不够强例如

Email            Password     Valid
abc@gmail.com    123Ab!         Yes
ab.com           123Ab!         invalid email
abc@gmail.com    12345          weak password

第三：不要重复使用同一封电子邮件

要了解更多信息，请捕获异常并进行打印

firebaseAuth.createUserWithEmailAndPassword(emailstring,passstring).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {
            if(task.isSuccessful())
            {
                Toast.makeText(reg2activity.this,"Regestration successful",Toast.LENGTH_LONG).show();
            }
            else
            {
                task.getException().printStackTrace();
                // add this ^^^^^^^^^^^^^^^^^^^^^^^
                Toast.makeText(reg2activity.this,"Regestration error",Toast.LENGTH_LONG).show();
            }
        }
    });
