java - Admob 初始化失败，App 启动时崩溃，即使没有错误

Question

我正在android studio中开发和android应用程序，即使该应用程序没有错误它在启动时崩溃我在google上研究过，堆栈溢出但这并不能解决我的问题应用程序的功能是生成随机数

注意：这是我第一次在我的应用中投放广告，所以我认为这可能会导致问题，但我仍然不确定。

这是MainActivity.java

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
import androidx.annotation.NonNull;
import com.example.randomnumbergenerator.R;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
import com.google.android.gms.ads.MobileAds;
import com.google.android.gms.ads.initialization.InitializationStatus;
import com.google.android.gms.ads.initialization.OnInitializationCompleteListener;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        MobileAds.initialize(this, new OnInitializationCompleteListener() {
            public void onInitializationComplete(@NonNull InitializationStatus initializationStatus) {
            }
        });

        AdView mAdView = findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        mAdView.loadAd(adRequest);
    }

主要活动 xml 文件

<?xml version="1.0" encoding="utf-8"?>

    xmlns:app="http://schemas.android.com/apk/res-auto"
