Exception when calling SchemaFactory.newInstance on Android 4.0
<p>I have an android 4.0 app which try to call the following as recommended in Android SDK:</p>

<pre><code>SchemaFactory sf = 
SchemaFactory.newInstance(javax.xml.XMLConstants.W3C_XML_SCHEMA_NS_URI); 
</code></pre>

<p>but this gives me the following exception: </p>

<pre><code>java.lang.IllegalArgumentException: http://www.w3.org/2001/XMLSchema 
</code></pre>

<p>my code:</p>

<pre><code>btnSearch.setOnClickListener(new Button.OnClickListener(){   
    public void onClick(View v) { 

    try{
        //no code before this line and exception threw right here.
        SchemaFactory sf = SchemaFactory.newInstance(javax.xml.XMLConstants.W3C_XML_SCHEMA_NS_URI);   
        ....
}
</code></pre>
