Detecting GPS on/off switch in Android phones

Question

I would like to detect when the user changes the GPS settings on or off for an Android phone. Meaning when user switches GPS sattelite on/off or detection via access points etc.

Answer 1

As I have found out the best way to do this is to attach to the

<action android:name="android.location.PROVIDERS_CHANGED" />

intent.

For instance:

<receiver android:name=".gps.GpsLocationReceiver">
        <intent-filter>
            <action android:name="android.location.PROVIDERS_CHANGED" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>

And then in the code:

public class GpsLocationReceiver extends BroadcastReceiver implements LocationListener 
...

@Override
public void onReceive(Context context, Intent intent)
{
        if (intent.getAction().matches("android.location.PROVIDERS_CHANGED"))
        { 
            // react on GPS provider change action 
        }
}
