मैंने कहाँ सेवा शुरू की? अनुप्रयोग वर्ग से

• startService(new Intent(getApplicationContext(),GeoFenceObserversationService.class));

मैंने जियोफ़ाइन्स कैसे पंजीकृत किया?

• GeoFenceObserversationService.getInstant().addGeofences();

जियोकोडर का उपयोग करके स्थान से पता प्राप्त करें

FusedAPI से आपको Location ऑब्जेक्ट मिल जाने के बाद, आप आसानी से उस ऑब्जेक्ट से Address जानकारी हासिल कर सकते हैं।

private Address getCountryInfo(Location location) {
    Address address = null;
    Geocoder geocoder = new Geocoder(getActivity(), Locale.getDefault());
    String errorMessage;
    List<Address> addresses = null;
    try {
        addresses = geocoder.getFromLocation(
                location.getLatitude(),
                location.getLongitude(),
                // In this sample, get just a single address.
                1);
    } catch (IOException ioException) {
        // Catch network or other I/O problems.
        errorMessage = "IOException>>" + ioException.getMessage();
    } catch (IllegalArgumentException illegalArgumentException) {
        // Catch invalid latitude or longitude values.
        errorMessage = "IllegalArgumentException>>" + illegalArgumentException.getMessage();
    }
    if (addresses != null && !addresses.isEmpty()) {
        address = addresses.get(0);
    }
    return country;
}

एक प्रसारण में स्थान अद्यतन हो रहा है

आने वाले स्थान अपडेट को संभालने के लिए पहले एक ब्रॉडकास्टर क्लास बनाएँ:

public class LocationReceiver extends BroadcastReceiver implements Constants {

    @Override
     public void onReceive(Context context, Intent intent) {

        if (LocationResult.hasResult(intent)) {
            LocationResult locationResult = LocationResult.extractResult(intent);
            Location location = locationResult.getLastLocation();
            if (location != null) {
                // Do something with your location
            } else {
                Log.d(LocationReceiver.class.getSimpleName(), "*** location object is null ***");
            }
        }
    }
}

तब जब आप GoogleApiClient को ऑन-कनेक्टेड कॉलबैक से कनेक्ट करते हैं:

@Override
public void onConnected(Bundle connectionHint) {
    Intent backgroundIntent = new Intent(this, LocationReceiver.class);
    mBackgroundPendingIntent = backgroundPendingIntent.getBroadcast(getApplicationContext(), LOCATION_REUEST_CODE, backgroundIntent, PendingIntent.FLAG_CANCEL_CURRENT);
    mFusedLocationProviderApi.requestLocationUpdates(mLocationClient, mLocationRequest, backgroundPendingIntent);
}

उपयुक्त जीवनचक्र कॉलबैक में स्थान अद्यतन आशय को हटाना न भूलें:

@Override
public void onDestroy() {
    if (servicesAvailable && mLocationClient != null) {
        if (mLocationClient.isConnected()) {
            fusedLocationProviderApi.removeLocationUpdates(mLocationClient, backgroundPendingIntent);
            // Destroy the current location client
            mLocationClient = null;
        } else {
            mLocationClient.unregisterConnectionCallbacks(this);
            mLocationClient = null;
        }
    }
    super.onDestroy();
}
