У меня есть служба, которая отправляет уведомление, когда пользователь меняет свое местоположение. Эта служба работает нормально, но проблема возникает, когда пользователь закрывает приложение, когда служба закрывается.Храните сервис определения местоположения живым, когда приложение закрыто.
Как я могу сделать сервис еще живым, даже если приложение было закрыто?
Мой Сервис:
public class LocationService extends Service implements LocationListener {
public final static int MINUTE = 1000 * 60;
boolean isGPSEnabled = false;
boolean isNetworkEnabled = false;
boolean canGetLocation = false;
Location location; // location
double latitude = 0; // latitude
double longitude = 0; // longitude
String provider;
// The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10;
// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1 * MINUTE;
// Declaring a Location Manager
protected LocationManager locationManager;
// Binder given to clients
private final IBinder mBinder = new LocalBinder();
/**
* Class used for the client Binder. Because we know this service always
* runs in the same process as its clients, we don't need to deal with IPC.
*/
public class LocalBinder extends Binder {
public LocationService getService() {
// Return this instance of LocalService so clients can call public
// methods
return LocationService.this;
}
}
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}
public Location getLocation() {
try {
locationManager = (LocationManager) getBaseContext().getSystemService(LOCATION_SERVICE);
// getting GPS status
isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled && !isNetworkEnabled) {
// no network provider is enabled. DEFAULT COORDINATES
} else {
this.canGetLocation = true;
if (isNetworkEnabled) {
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES,
this);
Log.d("Network", "Network Enabled");
if (locationManager != null) {
location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}
// if GPS Enabled get lat/long using GPS Services
if (isGPSEnabled) {
if (location == null) {
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES,
this);
Log.d("GPS", "GPS Enabled");
if (locationManager != null) {
location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
Log.i("LOCATION", "Latitude: " + latitude + "- Longitude: " + longitude);
return location;
}
@Override
public void onLocationChanged(Location arg0) {
NotificationManager mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
Intent intent = null;
intent = new Intent(this, CompleteSurveyActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this).setSmallIcon(R.drawable.ic_launcher).setAutoCancel(true)
.setContentIntent(contentIntent).setContentTitle(this.getString(R.string.app_name)).setContentText("text");
// mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify((int) System.currentTimeMillis() % Integer.MAX_VALUE, mBuilder.build());
double longitude = location.getLongitude();
double latitude = location.getLatitude();
Log.i("LOCATION", "Latitude: " + latitude + "- Longitude: " + longitude);
}
@Override
public void onProviderDisabled(String arg0) {
}
@Override
public void onProviderEnabled(String arg0) {
}
@Override
public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
}
}
я назвал здесь:
public class MyActivity extends Activity {
LocationService mService;
boolean mBound = false;
private ServiceConnection mConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName className, IBinder service) {
// We've bound to LocalService, cast the IBinder and get
// LocalService instance
LocalBinder binder = (LocalBinder) service;
mService = binder.getService();
mBound = true;
}
@Override
public void onServiceDisconnected(ComponentName arg0) {
mBound = false;
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_activity);
exampleButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
initService();
}
});
}
public void initService() {
if (mBound)
mService.getLocation();
}
@Override
protected void onStart() {
super.onStart();
// Bind to LocalService
Intent intent = new Intent(this, LocationService.class);
bindService(intent, mConnection, Context.BIND_AUTO_CREATE);
}
@Override
protected void onStop() {
super.onStop();
// Unbind from the service
if (mBound) {
unbindService(mConnection);
mBound = false;
}
}
}
Manifest.xml
<service android:name=".LocationService" android:enabled="true"></service>
