I succeded to call activity from browser link with tag like this.

<a href="myapp://launch.myapp.com/activity2?var1=linkClicked">my app</a>

of cource I added actvity setting in AndroidManifest.xml like this.

<activity android:name=".Activity2" >
   <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="launch.myapp.com" android:scheme="myapp"
         android:pathPrefix="/activity2"></data>
   </intent-filter>
</activity>

I want to call back from the activity2 with a value.

Is there any way to receive some value from the activity that was launched by the browser like above?

In other words I want do something like onActivityResult in the browser and get a value from the activity and set the value on the web page which has launched the activity.
