How do I acquire my location for "Stormy" weather app?

I found this code which helps.

//Injected views above

LocationManager locationManager;

String provider;
Location location;

private double mLatitude;
private double mLongitude;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.inject(this);


    locationManager =(LocationManager)this.getSystemService(Context.LOCATION_SERVICE);
    Criteria c=new Criteria();
    //if we pass false than
    //it will check first satellite location than Internet and than Sim Network
    provider=locationManager.getBestProvider(c, false);
    location=locationManager.getLastKnownLocation(provider);
    if(location!=null)
    {
        DecimalFormat df = new DecimalFormat("##.####");
        double unformatedLatitude = location.getLatitude();
        double unformatmedLongitude =location.getLongitude();

        mLatitude = Double.valueOf(df.format(unformatedLatitude));
        mLongitude = Double.valueOf(df.format(unformatmedLongitude));

        Toast.makeText(this, "LOCATION SUCCESS!!!", Toast.LENGTH_LONG);
    }
    else
    {
        mLatitude = 40.7744;
        mLongitude = -73.9042;
        Toast.makeText(this, "ASTORIA DEFAULT", Toast.LENGTH_LONG).show();
    }




    mProgressBar.setVisibility(View.INVISIBLE);

I've been lookinginto this a bit and must say that it is not very easy!

I have so far got as far as being able to bring back my lat & long which I can pass to forecast.io in the URL.

If that would help you, I'll see if I can set up a Git repo and you can see my code. I'll be working more on it to try to bring back a town/city name next.

First, though, I'm updating it to show the next 5 days forecasts in swipable screens.

Happy to share the project! We can both work on it.

Steve.

In a nutshell you need to utilize the device's GPS and like Steve Hunter mentioned, pass that data to your weather API. That can be done using the location service provided by Android. There are many tutorials available on this process, one of which can be found here.

From a User Experience aspect, you will probably want to convert the Lat & Long data into a specific city as well. This can be a bit more cumbersome, but after working with several different APIs, I found Google's implementation to be rather straight forward and easy to implement.

Like Steve said, post back with any additional questions. I'm sure folks here on the forum will be pleased to assist.

Happy coding,

Ken

Thanks for quick response!

I'm looking into tutorials you recommended. Will come back to you as soon as i figure something out. Also I will look into getting location name. Will share when/if I get it working.

Cheers and thanks again

also don't forget to implement LocationListener

The only thing I can't get now is updating the location name, since it's not Alcatraz.... seems like there is no JSON data in forecast.io that returns the location/city name based on the coordinates

I finally figured out how it's done after reading all the material you guys recommended. Basically you have to build googleApiclient and connect it. And in onConnected method put the code to get coordinates from last location.

I've read something about reverse geocoding to get location name, but I couldn't be bothered to tweak it, seemed easier to change weather API. Now I use openweathermap.org, it returns location name.

Good luck

I used the refractored location example that Ben wrote and then added the code from Stormy to it.
