Android Google Maps SDK API Key未找到问题求助

我这个仿GeoGuessr的项目已经卡了快几周了，尤其是API密钥的配置怎么都不生效，完全摸不着头绪。我本来预期模拟器能正常加载随机位置的街景视图，但LogCat里一直弹出这个错误：

Caused by: java.lang.RuntimeException: API key not found. Check that is in the element of AndroidManifest.xml

我试过让GPT一步步带我排查问题，也跟着好几个YouTube教程重新配置了一遍，但还是没解决。我怀疑是不是我的项目根本没识别到配置的API密钥，下面是我的相关代码和配置文件：

MainActivity 代码 #

package com.example.hopefullyfinalgeoguessr;

import android.os.Bundle;

import com.google.android.gms.maps.OnStreetViewPanoramaReadyCallback;

import com.google.android.gms.maps.StreetViewPanorama;

import com.google.android.gms.maps.StreetViewPanoramaView;

import com.google.android.gms.maps.SupportStreetViewPanoramaFragment;

import com.google.android.gms.maps.model.LatLng;

import com.google.android.material.snackbar.Snackbar;

import androidx.appcompat.app.AppCompatActivity;

import android.view.View;

import androidx.navigation.NavController;

import androidx.navigation.Navigation;

import androidx.navigation.ui.AppBarConfiguration;

import androidx.navigation.ui.NavigationUI;

import com.example.hopefullyfinalgeoguessr.databinding.ActivityMainBinding;

import android.view.Menu;

import android.view.MenuItem;

import java.util.Random;

public class MainActivity extends AppCompatActivity implements OnStreetViewPanoramaReadyCallback {

private StreetViewPanorama streetViewPanorama;

private boolean secondlocation = false;

private static final double MIN_LATITUDE = -90;

private static final double MAX_LATITUDE = 90;

private static final double MIN_LONGITUDE = -180;

private static final double MAX_LONGITUDE = 180;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

SupportStreetViewPanoramaFragment streetViewPanoramaFragment = (SupportStreetViewPanoramaFragment)getSupportFragmentManager().findFragmentById(R.id.googlemapstreetview);

streetViewPanoramaFragment.getStreetViewPanoramaAsync(this);

}

@Override

public void onStreetViewPanoramaReady(StreetViewPanorama streetViewPanorama) {

Random random = new Random();

double lat = MIN_LATITUDE + (MAX_LATITUDE - MIN_LATITUDE) * random.nextDouble();

double lng = MIN_LONGITUDE + (MAX_LONGITUDE - MIN_LONGITUDE) * random.nextDouble();

LatLng randomLocation = new LatLng(lat,lng);

this.streetViewPanorama.setPosition(randomLocation);

}

}

AndroidManifest.xml 配置 #

我已经尝试了GPT的分步指导和多个YouTube教程，但问题依然存在。目前猜测是项目没有正确识别到我配置的API密钥，有没有大佬能帮我看看问题出在哪？
