Application compatibility between versions

Question

I can run my application on 1.5, 1.6 and 2.0 emulator and on a 1.5 device without any problems. But some of my users are reporting force close and strange menu entries (see the attachment) using 1.6 and higher version devices. Any ideas?

This screen should look like this: http://www.taypo.com/blog/WindowsLiveWriter/TurkceKlavye0.7_6F1/settings_0.7_2.png

And the code that generates this screen is:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"&gt;
        <PreferenceCategory android:title="@string/general_settings">
                <CheckBoxPreference android:title="@string/haptic_feedback" android:defaultValue="true"
                        android:summary="@string/haptic_feedback_summary" android:key="vibrate" />
                <CheckBoxPreference android:title="@string/sound_feedback" android:defaultValue="false"
                        android:summary="@string/sound_feedback_summary" android:key="sound" />
                <CheckBoxPreference android:title="@string/auto_caps" android:defaultValue="true"
                        android:summary="@string/auto_caps_summary" android:key="auto_caps" />
        </PreferenceCategory>
        <PreferenceCategory android:title="@string/layout_settings">
                <ListPreference android:title="@string/keyboard_layout" android:defaultValue="TRQ"
                        android:key="kbd_layout" android:entries="@array/layout_names" android:entryValues="@array/layout_values" />
        </PreferenceCategory>
</PreferenceScreen>

Those are references to entries in your strings.xml file. That should not have changed between versions. Are you using any localization for your resources? Lets say you have a values-en, and values-es, but you don't have a values then your app will support English and Spanish but if someone has their locale set to German you will get something that looks like this.
