Hi TY Kueh, 

The fitness tracking will actually need a customized make it native application which will have the RNBackgroundGeolocation React-Native package included.  You can find the apk file here . I hope this should solve the issue. 

Here is the procedure to be followed for creating a custom native application when using custom React-Native packages in your application. 

It works quite well for me. Have a look at the Screenshots below.
