Help with a custom View attributes inside a Android Library Project

Question

I have a custom PieTimer View in an Android Library Project

package com.mysite.android.library.pietimer;  public class PieTimerView extends View { ... 

I also have a XML attributes file which I use in my PieTimer

    TypedArray a = context.obtainStyledAttributes(attrs,         R.styleable.PieTimerView); 

The XML styleable file looks like this

<?xml version="1.0" encoding="utf-8"?> <resources>      <declare-styleable name="PieTimerView">         <attr name="max_size" format="dimension" />         <attr name="start_angle" format="string" />         <attr name="start_arc" format="string" />         <attr name="ok_color" format="color" />         <attr name="warning_color" format="color" />         <attr name="critical_color" format="color" />         <attr name="background_color" format="color" />     </declare-styleable> </resources> 

I have the PieTimer in a layout file for a project that uses the library, like this

<RelativeLayout      android:layout_width="fill_parent"     android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/root" android:layout_gravity="center_horizontal"     xmlns:app="http://schemas.android.com/apk/res/com.mysite.android.library.myapp"     xmlns:pie="com.mysite.library.pietimer"     >  <com.mysite.library.pietimer.PieTimerView     pie:start_angle="270"      pie:start_arc="0"      pie:max_size="70dp"     pie:ok_color="#9798AD"     pie:warning_color="#696DC1"     pie:critical_color="#E75757"     pie:background_color="#D3D6FF"      android:visibility="visible"     android:layout_height="wrap_content" android:id="@+id/clock"     android:layout_width="wrap_content"      android:layout_alignParentRight="true"> </com.mysite.library.pietimer.PieTimerView> 

Previously I was using the xmlns:app as the namespace for attributes like app:ok_color but when I made my project a library project and has a Free and Full version implementing the library, I found it no longer worked so I added the pie namespace.

The PieTimerView displays but the attributed do not work, they use the default (this was not occurring before) so there is some namespace conflict hapenning here.

What is the correct way of doing this?

I know this post is super old, but if anyone comes looking, this problem has been fixed in ADT revision 17+ . Any services or Activities declare the namespace as:

xmlns:custom="http://schemas.android.com/apk/res-auto" 

res-auto will be replaced at build time with the actual project package, so make sure you set up your attribute names to avoid collisions if at all possible.
