Error NullPointerException (Banner Ads)when running on tablets

[WEYE Studio]

Hi,

I develop app and put admob banner ads in it by xml code. App run good on almost all phones but when running on tablets (Nexus 10, FonePad 7, Galaxy Tab 3...), it issue error NullPointerException when open app.

App run good on Nexus 7. So I don't know what error?

I have xml file activity_main.xml. Content of it:

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

<LinearLayout android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"

  xmlns:android="http://schemas.android.com/apk/res/android"

  xmlns:ads="http://schemas.android.com/apk/res-auto">

    <RelativeLayout android:orientation="vertical" android:id="@+id/layout" android:layout_width="match_parent" android:layout_height="0.0dip" android:layout_weight="0.31">

        <ImageView android:id="@+id/mage" android:layout_width="match_parent" android:layout_height="match_parent" />

    </RelativeLayout>

  <com.google.android.gms.ads.AdView 

      android:id="@+id/adView"

      android:layout_width="match_parent"

      android:layout_height="wrap_content"

      ads:adSize="SMART_BANNER"

      ads:adUnitId="my unit ad id"/> 

</LinearLayout>

 

 And this is java code:

protected void onCreate(Bundle var1) {

      super.onCreate(var1);

      this.setContentView(R.layout.activity_main);

 

AdView adView = (AdView)this.findViewById(R.id.adView);

      AdRequest adRequest = new AdRequest.Builder()

      .build();

      adView.loadAd(adRequest);

} 

 

Logcast in eclipse show error at adView.loadAd.

Have method to fix it?

Please help me!!!

Thanks

Posting the stacktrace would help. And this is probably better asked on StackOverflow.

If your stacktrace goes no deeper than adView.loadAd() then it means AdVIew is undefined. Your XML and code appear fine, and since this only happens on tablets I suspect that your have defined a tablet specific layout that doesn't contain the AdView.

Thank you! 

I had important error and i fixed it. I added activity_main.xml to folders: layout-sw600dp and layout-sw720dp. Before I missed this :)
