I am having some problem for the following layout. The layout is very simple, just using tablelayout with 3 buttons in a row (view = landscape). However there is a "java.lang.NullPointerException " in the preview screen. I have tested and find that it is arised from the ad part, ie. if I delete the ad part, this java.lang.NullPointerException will disappear.
My questions are:
Does ad does not support landscape? Or how to modify the below code?
I would also adopt a interstitialAd. Does interstitialAd support landscape too?
Coding as follows:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"

android:layout_width="wrap_content"
android:layout_height="wrap_content" >

android:layout_width="wrap_content"

android:onClick="buttonC_click"
android:padding="2dp"
android:text="Pictures!"
android:textSize="20dp" />
</TableRow>
<com.google.ads.AdView
android:id="@+id/adView"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:background="@android:color/black"
android:text="Ads Unavailable"
android:textStyle="bold|italic"

</TableLayout>
