I'm not sure whether this is some deep secret (I guess not, because I borrowed this code from Settings app): String allowedProviders = LocationManager.GPS_PROVIDER + "," + LocationManager.NETWORK_PROVIDER; Settings.Secure.putString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED, allowedProviders);
This will enable both GPS and Network providers (at least in 1.5, I haven't tried 1.6 yet). I also searched in the forums and mailing lists to find how to do that and I read some explanations like "doing it automatically without user's knowledge is _forbidden_ because this effects the battery life". I think the same explanation is valid for WIFI but to enable it I just need to call WifiManager.setEnabled(true). The idea with <uses-permission> is good enough for me. Before installing any application the platform tells me "this app requests these and those permissions. do you want to give them to it?". For me as a techy this is enough to reject access to "INTERNET" and "SYSTEM_TOOLS" for some game I was going to install. But my application has completely different purpose and everything is well described in its description and I need GPS and/or WIFI and I don't see anything wrong with requesting permissions to change their state at installation time. > > > I was actually thinking of creating > > a location-based app, but am surprised to see this. > > If the user disables GPS, that is the user's right. > > If the user has GPS enabled, the GPS radio is still normally off, for > battery reasons, but it will automatically turn on once you request > location updates or something.
