[GoogleCodeExporter]

i open a pdf file.and scroll to a page 10 eg.

reopen the last pdf file, it can not restore recent data. such as 
zoom,top,left.  

i find it,and solve it.
<activity android:name=".OpenFileActivity" android:label="@string/app_name"
            android:configChanges="orientation|keyboardHidden">
===>
<activity android:name=".OpenFileActivity" android:label="@string/app_name"
            android:configChanges="orientation|keyboardHidden|screenSize">
the screen orientation changed, Activity will reload,so ,lost any data.
