Look at the second to last line of that XML you posted.

com.google.android.gms.ads.AdView

That's not a valid attribute. In fact, it looks like that line should not even be there, except for the "/>" part of it.

XML attributes are always of the format name="value".

You REALLY need to teach yourself about XML and how to recognize what is well-formed and mal-formed if you're going to do this stuff.

This should be fixed, but I don't know for sure because I don't do AdSense:

<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity"
package="com.app">

<com.admob.android.ads.AdView
    android:id="@+id/MainActivity"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_alignParentBottom="true"
    ads:adSize="BANNER"
    ads:adUnitId="ca-app-pub-"
    android:name="com.admob.android.ads.AdView"/>
</RelativeLayout>

The problem is you didn't remove the line I told you to remove.
