ENABLE and DISABLE the Datawedge through a Javascript Android bridge


one of my Customer has the below Question.....

There seems to be a way through a javascript-android-bridge to lock and unlock the datawedge. This is at http://techdocs.zebra.com/datawedge/7-1/guide/api/enabledatawedge/ and http://programmerguru.com/android-tutorial/binding-javascript-and-android-code-example/ described.

There seems to be also a way to use javascript-android-bridge to lock and unlock the DataWedge directly through JavaScript and Intents. Prerequisite is that a corresponding URL scheme is available.

To get ahead in this point, an example implementation is urgently needed.

Can someone help with that request ?
