I want to open my app using a url scheme, I searched on google an SO and found the below code.that people are saying that is working. but it is not working for me:

```
<intent-filter>
    <data android:scheme="shan"/>                
    <action android:name="android.intent.action.VIEW"/>
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
</intent-filter>

```

I have specified the above in my manifest under the activity. and when i type `shan://` from browser, it does not open the application. 

any idea what I am doing wrong here?
