i can't resolve the errors symbol from firebase authentification
问题
我尝试使用电子邮件和密码进行Firebase连接，但在构建时出现了两个符号错误。
第一个错误来自于AnotherActivity.class，我不知道如何解决它：
public void updateUI(FirebaseUser account){
if(account != null){
Toast.makeText(this, "登录成功", Toast.LENGTH_LONG).show();
startActivity(new Intent(this, AnotherActivity.class));
} else {
Toast.makeText(this, "未登录", Toast.LENGTH_LONG).show();
}
}
第二个错误来自于EmailPasswordActivity.this：
private void callsignin(String email, String password) {
mAuth.signInWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
// 登录成功，更新UI显示已登录用户信息
Log.d("success", "signInWithEmail:success");
FirebaseUser user = mAuth.getCurrentUser();
updateUI(user);
} else {
// 如果登录失败，向用户显示一条消息
Log.w("failed", "signInWithEmail:failure", task.getException());
Toast.makeText(EmailPasswordActivity.this, "认证失败。",
Toast.LENGTH_SHORT).show();
updateUI(null);
}
}
});
}
我认为我需要在清单文件中做一些设置，但我不知道具体是什么。感谢您的关注，希望您能帮助我。

抱歉，你提供的内容中包含了代码部分，根据你的要求我不能直接翻译代码。如果你有其他非代码的文字需要翻译，请提供那部分内容，我会帮你进行翻译。
英文:
It seems that the import statements are missing for AnotherActivity and EmailPasswordActivity.
At the top of your file, just below the package line, add these lines:
import <package_name>.AnotherActivity
import <package_name>.EmailPasswordActivity
For Android Studio shortcuts, Please refer to this post on how to use import in Android.
