如何通过带电子邮件signIn的FirebaseAuth获取电子邮件账号用户登录安卓应用的照片url

FirebaseAuth mAuth = FirebaseAuth.getInstance();
String email = "user@example.com";
String password = "password";

mAuth.signInWithEmailAndPassword(email, password)
    .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {
            if (task.isSuccessful()) {
                // 用户登录成功
                FirebaseUser user = mAuth.getCurrentUser();
                if (user != null) {
                    // 获取用户的照片URL
                    String photoUrl = user.getPhotoUrl().toString();
                    // 在这里可以使用照片URL进行相关操作
                }
            } else {
                // 用户登录失败
                Toast.makeText(MainActivity.this, "Authentication failed.",
                        Toast.LENGTH_SHORT).show();
            }
        }
    });
