I want to start a service, the service is basically a videoview on windowmanager. I want to start this videoview service even from other applications. this is my code intent-filter, Don't know where I went wrong.

  <service android:name=".VideoWindow">
     <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:mimeType="video/*"  />
            <data android:mimeType="application/x-quicktimeplayer*" />
            <data android:mimeType="application/x-mpeg" />

Unless you are the one writing those other applications, or you hire people to write those other applications, no other applications will start your service.

My guess, from your <intent-filter>, is that you think that if another app calls startActivity() on an ACTION_VIEW Intent, that this will start your service. This is incorrect. startActivity() starts an activity. It will not start a service, no matter what <intent-filter> that service has.
