Intent filter to catch links from SMS doesn't work

I've read many posts on stackoverflow and doc on the Android API in order to be able to catch links from SMS or mail. For example, if I receive开发者_运维知识库 a SMS containing a link like myapp://hello, I want to to be clickable and to open my application once clicked.

I found how to do it using an intent filter on the activity I want to activate. Here is my code:

   <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:scheme="myapp"></data>

I tried it first with android:scheme="http" and it worked well (when I clicked a link from a SMS, Android asked the user which app to use: browser or myapp). However when I want to do so with myapp instead of http, it doesn't work...indeed the link myapp://hello is not clickable...so it's impossible to launch myapp clicking on it...

Do you have any idea ? Do I have to activate something, somewhere to tell Android to parse this kind of addresses ?

Thanks
