Вот рабочий и проверенный код, который успешно устанавливает IntentService в качестве получателя для Intent, включенного в PendingIntent, используемого для обновлений местоположения, на основе найденного кода здесь.
Сначала 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());
}
}
}
}
И вот код операции, который регистрирует обновления местоположения с помощью PendingIntent
, который отправляется в 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();
}
}
