The problem is that you haven't used the recommended approach for an app that tracks the location of assets. And you've tried to update the location manually by the getCurrentLocation method. As matter of fact, the getCurrentLocation method is used when you won't need location updates constantly. For example, you only need just a single fresh location of a user, for registration, nearby search, etc.
When you need to track an asset constantly, you should listen for location updates by the requestLocationUpdates method. According to official recommendation
Appropriate use of location information can be beneficial to users of
your app. For example, if your app helps the user find their way while
walking or driving, or if your app tracks the location of assets, it
needs to get the location of the device at regular intervals.
Here I've implemented a full example

Important Notes
Make sure that you have both FINE and COARSE location permissions
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
COARSE Location and PRIORITY_HIGH_ACCURACY are VERY IMPORTANT if you want to retrieve the asset's location in the fastest interval. the below settings are very important as well.
locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(12000);
locationRequest.setFastestInterval(2000);
locationRequest.setWaitForAccurateLocation(true);
locationRequest.setSmallestDisplacement(0);
