Android Question Manifest editor - SetServiceAttribute - external module

If I set the following in the Manifest manually and then make the AndroidManifest file "read-only", the service seems to be running fine:

<service android:name="com.kct.bluetooth_demo.KCTBluetoothService"/>

I'd like to avoid keeping the AndroidManifest file "read-only" while developing so I have tried the following in the manifest editor:

SetServiceAttribute(com.kct.bluetooth_demo, android:name, "KCTBluetoothService")

Click to expand...

but I get an error as follows:

Error parsing manifest script:
Module com.kct.bluetooth_demo not found (Manifest Editor)

Click to expand...

"com.kct.bluetooth_demo" is part of my wrapper.

As a test, SetApplicationAttribute works fine with "com.kct.bluetooth_demo" and apparently, the module is found:

SetApplicationAttribute(android:name, "com.kct.bluetooth_demo.KCTApp")

Click to expand...

I guess it is something stupid but I cannot get it to work in the manifest editor. Any help/ideas?
