This simple Android app is to connect to the Mi Band and send the step data to Google Fit. It uses GadgetBridge, to connect en fetch the data from the watch. It is written in ionic using the cordova-plugin-gadgetbridge and cordova-plugin-health.
Due to the issue that the Mi Fit app does not sync the step data reliably.
The app will display two cards, one for the Mi Band data and one for the Google Fit data. Both can display the todays current step count as read from Mi Band and Google Fit respectively. Tap on the step count values to re-sync the number. If Google Fit has a lower step count press "SYNC TO GOOGLE FIT" to send the missing step count data to Google Fit. At max, data for 2 days is send synced.
If the band is connected to the Mi Fit app, first disconnect it in this app. This will disconnect and remove the device from the bluetooth settings. Also it can be useful to "forget" Mi Band device in the bluetooth settings of your Android device.
In the MITOGO app click Open GadgetBridge. This will pop-up a Gadgetbrige window, press the + button. Now gadgetbridge will start scanning for a device. This can take a while. After a while the name of the device will show up, click on the the name. A settings page will pop-up, click "back" to continue. Now a connection will be set-up. The Band will vibrate, click the button on your Band.
To send data to Google Fit the app should be linked to Google Fit. Press "AUTHORIZE APP FOR GOOGLE FIT" and follow the instructions allowing read/write access to activity data. This requires a active internet connection and that the Google Fit App is installed on the device.
The App is using
See Ionic docs to setup your environment
run
> ionic cordova prepare android
> npm install
> ionic cordova build android --debug
Allow the app to access the Google Fitness API. Goto https://console.developers.google.com/apis, goto credentials, select create credentials, go to OAuth Client ID,Enable APIS and Services, enable Google Fitness.
To get SHA1 certificate fingerprints of your apk run:
keytool -list -printcert -jarfile yourapp.apk
- currently app only shows data for current day this can be extended to display other days
- display bar graph of last week
- there is an issue with back button on main screen. It should be disabled in Ionic, but it still seem to reset the app.
- The App icon is displayed ok on Android 5.1. But on Android 8 it displays the GadgetBridge Icon.
- there is a issue with Angular zone, not updating the view, which seem to occure on resuming the app. Even running
ChangeDetectorRef.detectChanges()doesn't seem to work.

It seems that wrapping the code in NgZone.run() did work, while ChangeDetectorRef.detectChanges() did not.
