Question

I’m writing a method that will return true if there’s a GPS sensor present and enabled, but returns false if it’s absent or switched off. It’s proving hard because…

hasSystemFeature("FEATURE_LOCATION_GPS")  // on PackageManager

Returns false, whether the device has a GPS or not. So even on a device that has one, and it’s switched on, it still returns false. Seems completely wrong to me, but I can’t see why.

isProviderEnabled("gps")   // on LocationManager

Returns true, even on a device I have here that has no GPS hardware at all. That also seems completely counter-intuitive.

I accept these results could be because I’m missing something, the SDK isn’t intuitive, or perhaps even that the devices I’m testing with are behaving strangely.

What am I missing?

Answer 1

This should work. Is there any error messages in logcat when you make this call?

PackageManager pm = getPackageManager();
boolean hasGps = pm.hasSystemFeature(PackageManager.FEATURE_LOCATION_GPS);
