java - Android OpenCV : No resource identifier found for attribute 'camera_id' in package -


i have opencv , android set in eclipse. following 1 of layout files:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"         xmlns:tools="http://schemas.android.com/tools"         xmlns:opencv="http://schemas.android.com/apk/res-auto"         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:orientation="vertical" >      <org.opencv.android.javacameraview         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:visibility="gone"         android:id="@+id/hello"         opencv:show_fps="true"         opencv:camera_id="any" /> </linearlayout>

the eclipse compiler complains about:

no resource identifier found attribute 'show_fps' in package  no resource identifier found attribute 'camera_id' in package

please add following resource file in project's values directory : 

attrs.xml

with following content : 

<?xml version="1.0" encoding="utf-8"?> <resources>     <declare-styleable name = "camerabridgeviewbase" >        <attr name="show_fps" format="boolean"/>        <attr name="camera_id" format="integer" >           <enum name="any" value="-1" />           <enum name="back" value="0" />           <enum name="front" value="1" />        </attr>     </declare-styleable> </resources>
