将 Google 广告横幅添加到我的 Android-Studio 项目不起作用。
如果有人能帮助我，我将非常非常感激。我只是不明白我做错了什么。 :/
我遵循的教程是：https://www.youtube.com/watch?v=w7muIkMYE_A
编辑：现在我稍微更改了代码，出现了一个新错误。
安卓清单：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="de.codereddev.howtoandroidsoundboard">
...
<application

android:authorities="${applicationId}.fileprovider"
android:name="android.support.v4.content.FileProvider"
android:exported="false"
android:grantUriPermissions="true">
</provider>
</application>
</manifest>
我的 SoundboardActivity 类没有变化：
public class SoundboardActivity
extends AppCompatActivity implements
LoaderManager.LoaderCallbacks<ArrayList<SoundObject>> {
AdView mAdview;
...
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_soundboard);
MobileAds.initialize(this, "ca-app-pub-3940256099942544~3347511713");
mAdview = (AdView)findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build();
mAdview.loadAd(adRequest);
...
新的错误是：

可能是Manifest文件的问题..
尝试清单以下类型..
<?xml version="1.0" encoding="utf-8"?>
<!-- Sample AdMob App ID: ca-app-pub-3940256099942544~3347511713 -->
<meta-data
android:name="com.google.android.gms.ads.APPLICATION_ID"
android:value="ca-app-pub-3940256099942544~3347511713"/>
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
