react-native-background-geolocation: Android Location services abruptly terminated after ~ 1 onLocation event

In the android environment, app will work when the stars align, but something often causes the location tracking to crash, leading to no more onLocation events for unknown reason. Most often this occurs more or less straight away, if the app begins tracking for more than a handful of updates it usually keeps tracking

Your Environment

  • Plugin version: 3.9.0
  • Platform: Android
  • OS version: pixel 2 api 30
  • Device manufacturer / model:
  • React Native version (react-native -v): 0.63.2
  • Plugin config ( in componentDidMount, in a screen component)
    BackgroundGeolocation.ready(
      {
        reset: true, // <-- true to always apply the supplied config
        distanceFilter: 1,
        logLevel: 5,
        debug: true // <-- enable debug sounds/notifications
      },
      (state) => {
        BackgroundGeolocation.start(function () {
          console.log("- Started background Geolocation successfully");
        });
      }
    );
    
    BackgroundGeolocation.onLocation((position) => {
      this.trackPosition(position);
    //   this.saveState();
    }, this.onError);

Expected Behavior

OnLocation fires according to distance parameter, so a few times a second.

Actual Behavior

onLocation fires once then bggeolocation records termination in logs. This isn’t universal behaviour, under certain conditions onLocation will fire as expected, i have not managed to spot a consistent pattern in this behaviour yet. App works as expected in iOS Simulator Stripped back or not.

Steps to Reproduce

I have stripped back the screen responsible for tracking in the app till it more or less resembles the most basic examples given in the Docs. TrackPosition currently just logs to console.

@btuck044 The onMotionChange event is not very sensitive. The confusion for me arose in that the iOS simulator registered moving just fine, and the android VM ‘sometimes’ did, so it was confusing to work out exactly why it would sometimes work and others not. If the android VM couldn’t fire the onMoving because no gyro feedback then fine, but then it would never work, rather than work sporadically. Then when dealing with a real device walking or cycling around nearby, the code i wrote would not behave as sensitively as the demo app does, which was my problem, so what was the difference?

The philosophy of operation that Chris loves does hint at the answer, but it would really be a lot easier if it was explicitly said at some point that the motion sensitivity is often not hugely sensitive so at least for smaller, non motor vehicle tracking it is best that you manually switch the plugin to a moving state using the changePace(true) method, which is exactly what the demo app does.

In fact i would imagine including the changePace(true) method on the front page basic usage description with a brief explanation of the limits of device/VM sensitivity with respect to the philosophy of operation / isMoving recognition would both serve to manage expectations and save people the time of rooting through the demo app code to find that one line that is far more important than is let on.
