title: Android Full Screen on Tablet
body: <p>I've developed an app on Android. The screen displays well on the mobile phone - eg shows full screen. But when I run it on my Samsung tablet 10 inch - it covers only a quarter of the screen. Here is my layout file:</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                  android:layout_width="fill_parent" 
                  android:layout_height="wrap_content"
                  android:background="@drawable/background"
                  android:padding="10px"&gt;
      &lt;AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
                      android:layout_width="fill_parent" 
                      android:layout_height="wrap_content"
  
                      android:gravity="center" &gt;
          &lt;ImageView
  android:id="@+id/mainheader"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_x="30px"
  android:layout_y="5px"
  android:src="@drawable/mainheader"
  /&gt;
  
          &lt;TextView android:id="@+id/err"
                          android:layout_width="wrap_content"
                          android:layout_height="wrap_content"
