unfortunately the app has stopped

here is my code:

xml layout:

 <?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
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:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.ajater.mj.vaccalc.MainActivity"
xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads">


   <com.google.ads.AdView
    xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads"
    android:id="@+id/adView"
    android:layout_width="wrap_content"

mainactivity

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

AndroidManifest

    package="my.app.name">

I think you need to add this line above your AdView

 MobileAds.initialize(getApplicationContext(), "Your own admob ad-unit");

Note: Don't test your real admob ad-unit. If so, There is chance to terminate your admob account by google.

Try this code,

<com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ads:adSize="BANNER"
        ads:adUnitId="@string/banner_key">
    </com.google.android.gms.ads.AdView>
