I've next problem. I create next attr.xml :
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="PublicMap">
        <attr name="public_map" format="boolean"/>
    </declare-styleable>
    <declare-styleable name="SceneMap">
        <attr name="public_map" format="boolean"/>
        <attr name="preview_mode" format="boolean"/>
    </declare-styleable>
</resources>
now project can not be compiled. Error is "error: Attribute "public_map" has already been defined". Is not possible to declare attributes with the same name for different views?
