Previously, the DeviceCommunicationService was invoked directly,
via
Intent intent = new Intent(foo, bar);
intent.setExtra(EXTRA_BAZ, baz);
startService(...);
and this was scattered throughout GadgetBridge.
Now there is a "frontend" available, so that you can call
the service more easily, like
GBApplication.deviceService().connect();
For a start, this client interface (DeviceService) actually
implements the same interface (EventHandler) as the receiving side
(DeviceSupport). This may change in the future.
This will also make testing much easier, because we can use
this client interface to invoke the test service as well.
- version information is now provided implicitly by device initialization
- ACTION_REQUEST_VERSIONINFO is now ACTION_REQUEST_DEVICEINFO and it will
return the current device state of the service without asking any DeviceSupport
instance.
- ACTION_CONNECT now implicitly answers with a device update intent if it
IS already connected.
In a second step, request the version from the device (and send updated
values then)
RequestVersionInfo is either a misnomer or misused, depending on your view.
It is actually used by activities to get the current state of thde device.
We now provide this as quickly as possible, with the drawback of sometimes
sending results twice.
Due to a bug in DeviceCommunicationService.isConnected(), devices using the
INITIALIZED state only worked when they had useAutoConnect set to true (Mi Band)
Now setting devices to INITIALIZED state to allow any action send to
DeviceCommunicationService is mandatory. As an exception only
REQUEST_VERSIONINFO will be also be allowed for CONNECTED state.
This also fixes a problem when notifications came in on the Pebble with 3.x
FW before we actually knew it was FW 3.x (INITZALIZED state on the Pebble
now implies that we know the FW version)
