Associate file extension with air app on Android

Hi,

I am trying to associate a file extension with my air app on Android. My goal is to be able to start my app by clicking on a file with a specific file type from either a file manager or mail app. I have found a solution that in theory would work in native, but does not with air somehow.

In the .xml-file for the app, under the <android> tag I have written:

<activity>

        <intent-filter>

            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />

            <category android:name="android.intent.category.DEFAULT" />

            <category android:name="android.intent.category.BROWSABLE" />

            <data android:scheme="file" />

            <data android:pathPattern=".*\\.csml" />

            <data android:host="*" />

        </intent-filter>

    </activity>

Does anyone have an idea how this could be solved?

Thanks in advance

Jens
