Is there any way using Intent as below :
To disable the App Switch button in KitKat. (Option Menu Key in JellyBean but App Switch Button in KitKat.)
You may be able to do this with the StageNow 2.1 tool i.e. create a profile with the KeyMappingMgr Setting type and then select the menu button and change the key behaviour to 'suppress key'. Create the profile barcode, read it with the StageNow client on the device and the menu key should be disabled.
