I think maybe where you have
mInfo = ((TextView) findViewById(R.string.infomation));
it is not getting a view back. Usually R.string.information would be
referring to a field like
android:id="@+id/information"
Which would be an attribute of the TextView from your layout XML
file.
You example is referring to something not a TextView ID string.
Hope this helps!
