This avoids a lot of problems because java
- does not know unsigned values
- jvm and dalvic do not internally support byte and short
- sqlite does not know them either
Currently we get the heart rate when synchronizing activity data
(i.e. not live) and we write it to the activity database so that we
can show a nice graph. The value is currently always 0 though,
because we can't enable recording hr, yet.
The reason being that we filter samples by activity kind
and then calculate the total sleep time using a delta between two
consecutive sample timestamps. But due to filtering of samples, not
all samples are consecutive. Instead of we have "holes" and add those
to your sleep time.
The data in the db is correct though (it always is), it's just the
display in the app that is wrong.
- model package contains mostly shared interfaces (UI+service), not named GB*
- impl package contains implementations of those interfaces, named GB*
the impl classes should not be used by the service (not completely done)
- the service classes should mostly use classes inside the service and deviceevents
packages (tbd)
Every device now has two packages:
- devices/[device name] for UI related functionality
- service[device name] for lowlevel communication
