Adding Google Ad Banners to my Android-Studio Project does not work.
I would be very very thankful, if anyone could help me. I just do not understand what I did wrong. :/
The tutorial I followed was: https://www.youtube.com/watch?v=w7muIkMYE_A

EDIT: Now I changed the code a bit and a new error occured.
Android Manifest:

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

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="de.codereddev.howtoandroidsoundboard">

 ...

 <application
 android:allowBackup="true"
 android:icon="@mipmap/ic_launcher"
 android:label="@string/app_name"
 android:supportsRtl="true"
 android:theme="@style/AppTheme">

<!--
 <meta-data
 android:name="android.support.FILE_PROVIDER_PATHS"
 android:resource="@xml/filepaths"/>

 <meta-data

 <activity
 android:name=".SoundboardActivity"
 android:label="@string/app_name">
 <intent-filter>
 <action android:name="android.intent.action.MAIN" />
 <category android:name="android.intent.category.LAUNCHER" />
 </intent-filter>
 </activity>
 <activity android:name=".FavoriteActivity" />

 <!-- Necessary for sharing sounds on Android 5.1+ -->
 <provider
 android:authorities="$applicationId.fileprovider"
 android:name="android.support.v4.content.FileProvider"
 android:exported="false"
 android:grantUriPermissions="true">
 </provider>
 </application>
</manifest>

No changes in my SoundboardActivity class:

 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);
 ...

The new error is:

Maybe the problem in the Manifest file..

Try Manifest the below type ..

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

<application
 android:allowBackup="true"
 android:icon="@drawable/ic_launcher"
 android:label="@string/app_name"
 android:theme="@style/AppTheme" >

 <meta-data
 android:name="com.google.android.gms.ads.APPLICATION_ID"
 android:value="ca-app-pub-3940256099942544~3347511713"/>

 android:name=".MainActivity"
 android:label="@string/app_name" >

 <category android:name="android.intent.category.LAUNCHER" />
 </intent-filter>
 </activity>
</application>
