- Migrate language setting
- Migrate menu items setting
- Migrate lastsync timestamp from prefixed global shared prefercence
All settings should be automatically be converted (e.g. Amazfit Bip settings to all paired Amazfit Bip devices) and then deleted.
Cor Settings aleady completely vanished from the global settings menu.
When migration is done we will have a much cleaner settings menu. Will also remove confusion that some Cor settings have to be done in Bip settings.
When connecting to a new device, a random key gets generated, which can be
looked up from the device specific settings (accessible via the gear icon in
the device card in the main activity). Old devices keep their 0123456789@ABCDE
key, they have to be re-paired to change that.
During pairing, long-pressing the device candidate in the discovery activity
will also start the device specific settings activity, where the auth key
can be set manually priror to pairing. This is usefull to keep the ability to
pair one device with multiple android devices.
