Question

I am still new to Android development, and I still don’t know a decent way to write code. Currently I throw everything into my MainActivity. But I don’t think that is a good way to write it. I have been searching Google, but I don’t really know what to search for. Does anyone have any tips?

I was going to try and take some code that I have and throw it into a view, but when I do I get errors.

For example when I place this in a view, I get cannot find symbol LOCATION_SERVICE

public class MainView extends View{
    public double[] getLoc(){
        // Get the location manager
        LocationManager locationManager = (LocationManager)getSystemService(LOCATION_SERVICE);
    }
}

That is basically a snippet from a function that gets a users latitude and longitude. It doesn’t work in a view I assume. The code does work in my MainActivity though.

Answer 1

use

LocationManager locationManager =
                     (LocationManager)getSystemService(Context.LOCATION_SERVICE);

instead of

LocationManager locationManager = 
                     (LocationManager)getSystemService(LOCATION_SERVICE);

for accessing LOCATION_SERVICE

and you also need to use current context for calling getSystemService method to get Service as :

public class MainView extends View{
Context context;

public MainView(Context context){
this.context=context;
}

   public double[] getLoc(){
        // Get the location manager
        LocationManager locationManager = 
           (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
    }
}
