我在跑步：

package com.example.projectTest;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

public class WelcomePage extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_welcome_page);
    }
}

与：

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".WelcomePage">

</androidx.constraintlayout.widget.ConstraintLayout>

但是当我运行时，在logcat中得到了以下错误：

Could not get package user id: run-as: unknown package: com.example.projectTest
Could not find apks for this package: com.example.projectTest

启动成功，但模拟器上没有显示任何应用（Pixel 6 API 32）。可能是什么问题？谢谢。
