* When handling clicks in a widget ListView, a single PendingIntent template is provided to

* on each list element; when a click is received, this "fillInIntent" is merged with the

|
* Intent.setDataAndType()

* The mime type MUST be set in the Intent, even though we do not use it; therefore, it's value
|

* Our "command" Uri is NOT used by the system in any manner, and is therefore constrained only
|
|
* in the requirement that it be syntactically valid.

* We use the following convention for our commands:
