Intent filter browser android:pathPrefix url param

问题:

So I'd like my activity to catch when an intent (browser) calls the link:

http://host/info?username=samplename 

and not when:

http://host/info?username=noname 

Here is my code coming from AndroidManifest.xml

<intent-filter>
   <action android:name="android.intent.action.VIEW"></action>
   <category android:name="android.intent.category.DEFAULT"></category>
   <category android:name="android.intent.category.BROWSABLE"></category>\
   <data android:host="host" android:pathPrefix="/info?username=samplename" android:scheme="http"></data>
</intent-filter>

I have it working for a simple prefix such as android:pathPrefix="/info" But I have problem with the character ? I tried using \? but doesn't work http://developer.android.com/guide/topics/manifest/data-element.html#path

Anybody would have any idea?

Thanks

Have you tried \\?

Because '\' is used as an escape character when the string is read from XML (before it is parsed as a pattern), you will need to double-escape: For example, a literal '' would be written as "\" and a literal '\' would be written as "\\". This is basically the same as what you would need to write if constructing the string in Java code.
