I have an Android app that uses tabs for its start menu. The tabs don't
display when I port the app to a Kindle Fire. Here's the code:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_height="wrap_content"
android:layout_width="fill_parent"

}

tabhost.addTab(spec_adv);

}}
Does anyone know why? The tabs and their contents show up fine in the
emulator and on my Android phone. Thanks!
