Why Isn\'t My Android App Updating Location Using the NETWORK Provider?

How to Get the Current Location Using the NETWORK Provider in Android

Retrieving the current location in Android is a common task for mobile applications. When using the NETWORK provider, however, it's crucial to understand the underlying mechanism. In this article, we will explore why the original code provided in the question is not updating the location when the NETWORK provider is used.

The Issue with the Original Code

The original code utilizes the LocationManager to request location updates. While it correctly handles GPS positioning, it fails to properly handle NETWORK positioning. This is because the code doesn't define a LocationListener to handle location changes.

Defining a LocationListener

In order to receive location updates, you need to define a LocationListener object. This object will be called whenever the location changes. The following code snippet demonstrates how to do this:

private final LocationListener mLocationListener = new LocationListener() {
    @Override
    public void onLocationChanged(Location location) {
        // Your code here to handle the location change
    }
};

Requesting Location Updates

Once you have defined a LocationListener, you need to request location updates from the LocationManager. The following code snippet shows how to request updates from the GPS provider:

mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, LOCATION_REFRESH_TIME,
LOCATION_REFRESH_DISTANCE, mLocationListener);

Similarly, to request updates from the NETWORK provider, use the following code:

mLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, LOCATION_REFRESH_TIME,
LOCATION_REFRESH_DISTANCE, mLocationListener);

Permission Declaration

Don't forget to declare the appropriate permissions in your AndroidManifest.xml file. For using the NETWORK provider, you need the following permission:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>

Conclusion

By defining a LocationListener and requesting location updates from the NETWORK provider, you can now successfully retrieve the current location using the NETWORK provider in your Android application.
