Can't Get Gps Coordinates In Android Application

I use this code to get the current location's coordinates. When I start this activity, nothing happens. When I use this exact code in another application it worked. The only differ

Solution 1:

Hope this might help

Edit:

publicclassMainActivityextendsAppCompatActivityimplementsGoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener {
    privatestatic final int PERMISSION_REQUEST_ACCESS_FINE_LOCATION = 100;

    privateLocationRequest mLocationRequest;
    privateGoogleApiClient mGoogleApiClient;
    privateTextView mLatitudeTextView;
    privateTextView mLongitudeTextView;

    @OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mLatitudeTextView = (TextView) findViewById((R.id.latitude_textview));
    mLongitudeTextView = (TextView) findViewById((R.id.longitude_textview));

        createLocationRequest();
        mGoogleApiClient = newGoogleApiClient.Builder(this)
                .addApi(LocationServices.API)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)

        if (!checkPermissions()) requestPermissions();

    }

    privatevoidrequestPermissions() {

    }

    privatevoidcreateLocationRequest() {
        mLocationRequest = newLocationRequest();
        mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

    @OverridepublicvoidonRequestPermissionsResult(int requestCode, @NonNullString[] permissions, @NonNull int[] grantResults) {
        switch (requestCode) {

                } else {

                }
            }
        }
    }
}

In onLocationChanged() you get location which you can use to get latitude and longitude. Also, this code does not give continuous location updates. For that you have to set UPDATE INTERVAL & FASTEST UPDATE INTERVAL in method createLocationRequest().
