for me seems "resources" wrong tag or that. so? tag need?

remove <resources> tag res/xml/defaults.xml

that file should this:

<?xml version="1.0" encoding="utf-8"?>

<preferencecategory android:title="preferencecategory a"> <checkboxpreference android:key="checkbox_preference" android:title="title_checkbox_preference" android:summary="summary_checkbox_preference" /> </preferencecategory> <preferencecategory android:title="preferencecategory b"> <edittextpreference android:key="edittext_preference" android:title="title_edittext_preference" android:summary="summary_edittext_preference" android:dialogtitle="dialog_title_edittext_preference" /> </preferencecategory>
