如何检查 android 设备是否支持 gps？

Question

i'm trying to write a method which checks the gps support of android device. Although having gps support on emulator, it always returns false. But when i try it on my android devices it returns true. What can be reason of that?

public boolean isGpsAvailable() {
    PackageManager pm = this.getPackageManager();
    if (pm.hasSystemFeature(PackageManager.FEATURE_LOCATION_GPS)) {
        return true;
    } else {
        return false;
    }
}

If you're using a LocationManager, you could use this method:

Then look through all of the strings returned, and see if one is a GPS provider.
