Send location updates to IntentService

Question

How can location updates be sent directly to Intent Service? The following approach does not work. OnConnected function is called but then the intent is never received in th

Answer 1

Here is working and tested code that successfully sets up an IntentService as the receiver for the Intent included in the PendingIntent used for location updates, based on code found here.

First, the IntentService:

import android.app.IntentService;
import android.content.Intent;
import android.location.Location;
import android.util.Log;
import com.google.android.gms.location.FusedLocationProviderApi;
import com.google.android.gms.location.LocationResult;

public class LocationUpdateService extends IntentService {

    private final String TAG = "LocationUpdateService";
    Location location;

    public LocationUpdateService() {

        super("LocationUpdateService");
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        if (LocationResult.hasResult(intent)) {
            LocationResult locationResult = LocationResult.extractResult(intent);
            Location location = locationResult.getLastLocation();
            if (location != null) {
                 Log.d("locationtesting", "accuracy: " + location.getAccuracy() + " lat: " + location.getLatitude() + " lon: " + location.getLongitude());
            }
        }
    }
}

And here is the Activity code that registers for location updates with a PendingIntent that is sent to the IntentService:

import android.app.PendingIntent;
import android.os.Bundle;
import android.content.Intent;
import android.app.Activity;
import android.widget.Toast;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.location.LocationRequest;
import com.google.android.gms.location.LocationServices;

public class MainActivity extends Activity implements
        GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {

    LocationRequest mLocationRequest;
    GoogleApiClient mGoogleApiClient;
    PendingIntent mRequestLocationUpdatesPendingIntent;

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

        buildGoogleApiClient();
        mGoogleApiClient.connect();
    }

    @Override
    protected void onPause(){
        super.onPause();
        if (mGoogleApiClient != null) {
            LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, mRequestLocationUpdatesPendingIntent);
        }
    }

    protected synchronized void buildGoogleApiClient() {
        Toast.makeText(this,"buildGoogleApiClient",Toast.LENGTH_SHORT).show();
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
    }

    @Override
    public void onConnected(Bundle bundle) {
        Toast.makeText(this,"onConnected",Toast.LENGTH_SHORT).show();

        mLocationRequest = new LocationRequest();
        mLocationRequest.setInterval(10);
        mLocationRequest.setFastestInterval(10);
        mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
        //mLocationRequest.setSmallestDisplacement(0.1F);

        // create the Intent to use WebViewActivity to handle results
        Intent mRequestLocationUpdatesIntent = new Intent(this, LocationUpdateService.class);

        // create a PendingIntent
        mRequestLocationUpdatesPendingIntent = PendingIntent.getService(getApplicationContext(), 0,
                mRequestLocationUpdatesIntent,
                PendingIntent.FLAG_UPDATE_CURRENT);

        // request location updates
        LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,
                mLocationRequest,
                mRequestLocationUpdatesPendingIntent);
    }

    @Override
    public void onConnectionSuspended(int i) {
        Toast.makeText(this,"onConnectionSuspended",Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        Toast.makeText(this,"onConnectionFailed",Toast.LENGTH_SHORT).show();
    }
}

Resulting logs:
