[Ovmsdev] Android App beta

Chris,

"com.openvehicles.OVMS.SendCommand" is the old command action, it's 
still supported and should work the same way as before, except there are 
some new extras in the response intent.

The "SendCommand" interface is raw MP function level, that's why you 
need to prefix "7," for text commands (7 = execute text command). Other 
MP commands work just the same way as raw commands, e.g. "20,<pin>" will 
lock the car if supported. 
(https://docs.openvehicles.com/en/latest/protocol_v2/commands.html)

The newly added command intent action is 
"com.openvehicles.OVMS.action.COMMAND", it just takes one extra 
"command", which takes the command just as entered in the notification 
page. See help there for the syntax, text commands can be given as in 
the shell, to send the above MP lock command, you'd enter "#20,<pin>". 
This action currently always sends the command to the currently selected 
vehicle.

KWGT doesn't support sending intents, that's why I've done all this.

To call a stored command from KWGT, set a suitable element's touch 
handler to "start shortcut". After clicking on that action, you can open 
a selector. It will show the list of shortcut providers installed 
including the OVMS App now. Click on the OVMS entry, then select the 
command from the list of stored commands.

Regards,
Michael
