you should specify different every intent can launch app. 1 browser category url data, , 1 launcher category.

from app manifest guide.

components advertise capabilities — kinds of intents can respond — through intent filters. since android system must learn intents component can handle before launches component, intent filters specified in manifest elements. a component may have number of filters, each 1 describing different capability.

your code become like:

    <intent-filter>         <action android:name="android.intent.action.main" />          <category android:name="android.intent.category.launcher" />     </intent-filter>     <intent-filter>         <action android:name="android.intent.action.view" />         <category android:name="android.intent.category.default" />         <category android:name="android.intent.category.browsable" />         <data             android:host="www.chillumapp.com"             android:pathprefix="/chillum"             android:scheme="http" />     </intent-filter>
