Retrieving Gps Coordinates When Location Services Are Not Enabled
Solution 1:
No. If the user doesn't want to give you his location, There is no way you can get his location.
This is a security measure and it exists for good reasons. If you try to subvert this, your app will be considered malicious.
Redirecting the user to the settings page is the best option.
Solution 2:
Agreed - in earlier versions of android, you could programatically turn on the GPS - but more recent versions do not allow this to happen. As Anup states - the common acceptable practice now is to redirect the user to the options page and allow the user to select the type and nature of GPS that the application is allowed to use.
Dont forget , you dont need to "leave the app" to get the user to turn on GPS, you can send them to the settings yourself:
startActivityForResult(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS), 0);
This will then come back to your app where it left off - giveing the use a seamless experience, and one which they will be familiar with from other android apps.
Solution 3:
Setting anything programatically without asking the user first is bad practice.
What you could do is, in case you can't get a location, ask the user to turn GPS on or tell him your app won't be able to work and will close.
Solution 4:
switching on Location settings programmatically without the users consent is impossible let alone bad practice. You can prompt the user and direct him to switch on location settings or if you program tracks the progress of the device user, you can have the program send an alert of some sort telling them that the Location setting is off.
Solution 5:
Deep dive into location has a set of best practices for Android's LocationManager. You do not need the GPS to be activated -- in many cases, the mobile network itself gives a pretty good approximation of the location without taking up extra battery.
