Stop location service after 6 hours from start time automatically

I have a location service which sends location to my server after every 3 minutes.This location service is started from Activity by click of a button.I want this service stops automatically after 6 hours from started time.Here is my service file.Service is starting normally and i am able to stop it by click of a button in activity.But i want to stop it automatically after 6 hours even app is minimized.Any help would be highly appreciated.
public class LocationService extends Service {
private LocationListener listener;
private LocationManager locationManager;
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
listener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
Log.i("location:","location is "+location.getLongitude()+" "+location.getLatitude());
LocationApi.sendGpsLocation(getApplicationContext(),location.getLongitude(),location.getLatitude());
}
#Override
public void onStatusChanged(String s, int i, Bundle bundle) {
}
#Override
public void onProviderEnabled(String s) {
}
#Override
public void onProviderDisabled(String provider) {
Log.e("disabled provider is :","location is "+provider);
Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
}
};
// locationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
if (ContextCompat.checkSelfPermission(DashboardActivity.activity, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED ) {
locationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,3000,0,listener);
}
}
/* #Override
public final void stopSelf(){
}*/
#Override
public boolean onUnbind(Intent intent) {
LocationApi.stopLocation(getApplicationContext());
//super.onDestroy();
if (locationManager != null) {
//noinspection MissingPermission
locationManager.removeUpdates(listener);
}
return super.onUnbind(intent);
}
#Override
public void onDestroy() {
LocationApi.stopLocation(getApplicationContext());
super.onDestroy();
if(locationManager != null){
//noinspection MissingPermission
locationManager.removeUpdates(listener);
}
}
}
and i start this service in Activity by below code.
Intent i = new Intent(getApplicationContext(), LocationService.class);
if (Build.VERSION.SDK_INT >= 26) {
startForegroundService(i);
}else{
startService(i);
}

You can add a counter to your 3 min timer and count up til you reach 120 and than stop Locationupdates and shutdown the service.

You could schedule an alarm via AlarmManager when the service gets started - this will be an Intent you receive. When receiving you can stop your running service.

Try this code:
public class LocationService extends Service {
public static final String ACTION_STOP = "com.mycompany.myapp.SERVICE_STOP";
/*private static final long UPDATE_INTERVAL = 3 * 60 * 1000;
private static final long STOP_INTERVAL = 6 * 3600 * 1000;*/
private static final long UPDATE_INTERVAL = 3 * 1000;
private static final long STOP_INTERVAL = 20 * 1000;
private LocationListener listener;
private LocationManager locationManager;
private BroadcastReceiver receiver;
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public int onStartCommand(Intent i, int flags, int startId){
if (Build.VERSION.SDK_INT >= 26){
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
NotificationChannel channel = new NotificationChannel("Location",
"Location", NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
Notification notif = new NotificationCompat.Builder(this, "Location")
.setContentTitle("Location service")
.build();
startForeground(3001, notif);
}
return START_STICKY;
}
#Override
public void onCreate() {
listener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
Log.i("location:","location is "+location.getLongitude()+" "+location.getLatitude());
LocationApi.sendGpsLocation(getApplicationContext(),location.getLongitude(),location.getLatitude());
}
#Override
public void onStatusChanged(String s, int i, Bundle bundle) {
}
#Override
public void onProviderEnabled(String s) {
}
#Override
public void onProviderDisabled(String provider) {
Log.e("disabled provider is :","location is "+provider);
Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
}
};
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED ) {
locationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,UPDATE_INTERVAL,0,listener);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,UPDATE_INTERVAL,0f,listener);
}
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent i = new Intent(ACTION_STOP);
PendingIntent pi = PendingIntent.getBroadcast(this, 100, i, PendingIntent.FLAG_UPDATE_CURRENT);
am.set(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime() + STOP_INTERVAL, pi);
receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
stopSelf();
}
};
IntentFilter filter = new IntentFilter();
filter.addAction(ACTION_STOP);
registerReceiver(receiver, filter);
}
#Override
public void onDestroy() {
Log.i("location:","stopping updates");
unregisterReceiver(receiver);
LocationApi.stopLocation(getApplicationContext());
super.onDestroy();
if(locationManager != null){
locationManager.removeUpdates(listener);
}
}
}
Explanation: use AlarmManager.set() to schedule a broadcast after certain time (STOP_INTERVAL). To receive the broadcast, register a receiver in onCreate(), and unregister it in onDestroy().

Implementing Google Location Services API inside a service

I have implemented Google Location Services inside a service, so that I can get location updates in the background (so that updates don't stop when user locks screen, switches fragment, etc.). But I am getting a strange error message that is stopping me from implementing it.
On the line:
"LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, locationRequest, this);"
It is telling me that 2rd parameter 'this' is not allowed and should be cast to (com.google.android.gms.location.LocationListener). But in every example I've seen this is not the case. When I do cast it, it does not work
Below is my code, trouble is in the onConnected method
public class LocationTrackingService extends Service implements LocationListener, ConnectionCallbacks, OnConnectionFailedListener {
GoogleApiClient googleApiClient = null;
LocationRequest locationRequest;
Location currentLocation;
static final int INTERVAL = 2000;
static final int FASTEST_INTERVAL = 500;
static final int PRIORITY = LocationRequest.PRIORITY_HIGH_ACCURACY;
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
setupGoogleApiClient();
createLocationRequest(INTERVAL, FASTEST_INTERVAL, PRIORITY);
googleApiClient.connect();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (!googleApiClient.isConnected()) {
googleApiClient.connect();
}
return super.onStartCommand(intent, flags, startId);
}
#Override
public void onDestroy() {
//TODO maybe dont need this
googleApiClient.disconnect();
super.onDestroy();
}
#Override
public void onLocationChanged(Location location) {
//updating current location
currentLocation = location;
//TODO will be writing directly to database here
//broadcasting intent
Intent publishLocationUpdate = new Intent("location_update");
publishLocationUpdate.putExtra("current_location", currentLocation);
sendBroadcast(publishLocationUpdate);
}
#Override
public void onStatusChanged(String s, int i, Bundle bundle) {
}
#Override
public void onProviderEnabled(String s) {
}
//if location tracking is not enabled
#Override
public void onProviderDisabled(String s) {
Intent toSettings = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
toSettings.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(toSettings);
}
#Override
public void onConnected(#Nullable Bundle bundle) {
//sets location to last known location
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions

// public void onRequestPermissionsResult(int requestCode, String[] permissions,

// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
currentLocation = FusedLocationApi.getLastLocation(googleApiClient);
//request updates
LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, locationRequest, this);
}
#Override
public void onConnectionSuspended(int i) {
}
#Override
public void onConnectionFailed(#NonNull ConnectionResult connectionResult) {
}
// Create an instance of GoogleAPIClient which we call to recieve location information
void setupGoogleApiClient(){
if (googleApiClient == null) {
googleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
}
//set request settings, interval: how soon until new request is made, priority affects batterylife (using GPS, netowork, data...)
void createLocationRequest(int interval, int fastestInterval, int priority) {
locationRequest = new LocationRequest();
locationRequest.setInterval(interval);
locationRequest.setFastestInterval(fastestInterval);
locationRequest.setPriority(priority);
//can also use PRIORITY_LOW_POWER, PRIORITY_BALANACED_POWER_ACCURACY, PRIORITY_NO_POWER
}
}
I check the intent in onResume in my fragment, code below:
if(broadcastReceiver == null){
broadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Location currentLocation;
currentLocation = (Location) intent.getExtras().get("current_location");
currentAltitudeTextView.setText(String.valueOf(currentLocation.getLatitude()));
currentSpeedTextView.setText(String.valueOf(currentLocation.getLongitude()));
}
};
}
context.registerReceiver(broadcastReceiver, new IntentFilter("location_update"));

GoogleApiClient onConnected not being called, using in a Service

Was working when I was using GoogleApiClient in an Activity but moved it to a Service and the onConnected is not being called.
public class StepsMonitoringService extends Service implements GoogleApiClient.ConnectionCallbacks {
private GoogleApiClient mClient;
#Override
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
mClient = new GoogleApiClient.Builder(this).addApi(Fitness.HISTORY_API)
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ))
.addConnectionCallbacks(this).build();
mClient.connect();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
return START_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
mClient.disconnect();
}
#Override
public void onConnected(Bundle connectionHint) {
// NOT being called!! WHY??
}
#Override
public void onConnectionSuspended(int cause) {
}
}
Any ideas anyone? What am I doing wrong? Has anyone got GoogleApiClient working in a Service?
The service is called from an Activity
public class MainActivity extends FragmentActivity {
private TextView mStepsView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(this, StepsMonitoringService.class);
startService(intent);
LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver, new IntentFilter("StepMonitoringServiceIntent"));
mStepsView = (TextView) findViewById(R.id.steps);
}
private void displayOnUI(String msg) {
mStepsView.setText(msg + "\n" + mStepsView.getText());
}
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
long steps = intent.getLongExtra("steps", 0);
displayOnUI(steps + " steps");
}
};
}
During debugging I can see the onCreate of the Service gets called, however the onConnected is never called. Nothing special in the logs from what I can see.

First implement these interfaces:
GoogleApiClient.ConnectionCallbacks
GoogleApiClient.OnConnectionFailedListener
Then you will have to add these methods to your class:
public void onConnected(final Bundle bundle)
public void onConnectionSuspended(final int i)
public void onConnectionFailed(final ConnectionResult connectionResult)
As soon as you connect, the OnConnected method will be called. In this method can you do whatever you want, like getting the current location, the location address, add a marker point to map, etc.
But you cannot do anything without establishing a connection to the Google API client.
To connect to the GoogleAPIClient, you can add this method to your class and call it in your onCreate method.
private synchronized void buildGoogleAPIClient(){
googleApiclient = new GoogleApiClient.Builder(getActivity())
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
googleApiclient.connect();
Toast.makeText(getActivity(), "connected", Toast.LENGTH_SHORT).show();
}

Add addOnConnectionFailedListener to GoogleApiClient to track the error. As per doc addOnConnectionFailedListener called when there was an error connecting the client to the service.
public class StepsMonitoringService extends Service implements GoogleApiClient.ConnectionCallbacks {
private GoogleApiClient mClient;
#Override
public void onCreate() {
super.onCreate();
mClient = new GoogleApiClient.Builder(this).addApi(Fitness.HISTORY_API)
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ))
.addConnectionCallbacks(this)
//Add Connection Failed Listener to track error.
.addOnConnectionFailedListener(this)
.build();
mClient.connect();
}
#Override
public void onConnected(Bundle connectionHint) {
// NOT being called!! WHY??
}
#Override
public void onConnectionSuspended(int cause) {
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
//Called called when there was an error connecting the client to the service.
Log.i(LOG_TAG,"onConnectionFailed:"+connectionResult.getErrorCode()+","+connectionResult.getErrorMessage());
}
}

try this.
public class StepsMonitoringService extends Service implements
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
/**
* Provides the entry point to Google Play services.
*/
protected GoogleApiClient mClient;
/**
* Builds a GoogleApiClient. Uses the addApi() method to request the
* Fitness API.
*/
protected synchronized void buildGoogleApiClient() {
mClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(Fitness.HISTORY_API)
.build();
}
#Override
public void onCreate() {
super.onCreate();
if (mClient == null) {
buildGoogleApiClient();
}
mClient.connect();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
return START_STICKY;
}
#Override
public void onConnected(Bundle connectionHint) {
// NOT being called!! WHY??
}
#Override
public void onConnectionSuspended(int cause) {
mClient.connect();
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
// Called called when there was an error connecting the client to the
// service.
Log.i(LOG_TAG,
"onConnectionFailed:" + connectionResult.getErrorCode() + "," + connectionResult.getErrorMessage());
}
}

I had a same issue when I was using useDefaultAccount() to create a client. I then replaced it with setAccountName() and it starts working. I think for some reasons accountpicker doesn't work in service that's why googleapiclient's connect() silently failed since you need specify which account you use for retrieving Fitness info. Noted that you need to have an account picker in your activity and pass the email account to your service in some way.

Initialing GoogleApiClient after boot

I'm registering my app after boot to receive location updates. My boot receiver is starting a service that does the initialization:
#Override
protected void onHandleIntent(Intent intent) {
GoogleApiClient client = _googleApiBuilder.get()
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
client.connect();
}
Sometimes in the onConnected callback method I'm getting exception indication I'm not connected yet. After some research I've encountered this - GoogleApiClient is throwing "GoogleApiClient is not connected yet" AFTER onConnected function getting called
It made me think, does the way I'm initializing google api is correct ? e.g. should I initialize it in a service ?
What is the suggested way to do it in the background ?

Hope it will be helpful to you.
public class LocationService extends Service implements ConnectionCallbacks,
OnConnectionFailedListener, LocationListener {
private static final String TAG = LocationService.class.getSimpleName();
private GoogleApiClient mGoogleApiClient;
#Override
public IBinder onBind(final Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
initGoogleApi();
}
#Override
public int onStartCommand(final Intent intent, final int flags,
final int startId) {
if (mGoogleApiClient != null) {
mGoogleApiClient.connect();
}
return START_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
}
#Override
public void onLocationChanged(final Location location) {
}
#Override
public void onConnectionFailed(final ConnectionResult result) {
}
#Override
public void onConnected(final Bundle bundale) {
createLocationRequest();
}
#Override
public void onConnectionSuspended(final int arg0) {
}
protected void stopLocationUpdates() {
LocationServices.FusedLocationApi.removeLocationUpdates(
mGoogleApiClient, this);
}
protected void createLocationRequest() {
final LocationRequest mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(Constants.INTERVAL);
mLocationRequest.setFastestInterval(Constants.FAST_INTERVAL);
mLocationRequest
.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
mLocationRequest.setSmallestDisplacement(0);
startLocationUpdates(mLocationRequest);
}
private void initGoogleApi() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API).addApi(ActivityRecognition.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).build();
}
}

Used the following solution instead:
googleApiInstance.blockingConnect(10, TimeUnit.SECONDS);
or in other words instead of running the operation in a different thread (that's what connect is doing), I'm running it in my own thread (I'm using IntentService) and manage the connection life cycle on my own.

Google ActivityRecognitionApi not firing any callbacks

GooglePlayServices recently changed from the way you detect the users activity - from using ActivityRecognitionClient to ActivityRecognitionApi. I have followed all the examples I can find but must have missed something.
After making the call to GoogleApiClient.Builder(mContext).addApi(ActivityRecognition.API)...build() I was expecting that one of the connection callback methods would be called. I have logging and breakpoints in all the callback methods but none of them are ever called.
OnReceive() and CallClient() are called as expected and the manifest file includes: uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION"
What am I missing? I would love to get to the bottom of this given the amount of time I have wasted so far.
(P.S. It's my own Logging library - it is not part of the issue)
public class BootAtStartupReceiver extends BroadcastReceiver implements GooglePlayServicesClient.ConnectionCallbacks, GooglePlayServicesClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener{
private final String TAG = getClass().getName();
private PendingIntent mpIntent;
private static GoogleApiClient mGoogleApiClient;
private Context mContext;
#Override
public void onReceive(Context context, Intent intent) {
Logging.log(Logging.enumLoggingLevel.d,TAG,"inside onReceive: " + intent.getAction());
if ((intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) || (intent.getAction().equals(BroadcastIntentConstants.ACTIVITY_FIRST_TIME_CALL_SERVICE)))
{
mContext = context;
callClient();
}
}
private void callClient() {
Logging.log(Logging.enumLoggingLevel.d,TAG,"inside callClient");
int resp = GooglePlayServicesUtil.isGooglePlayServicesAvailable(mContext);
if (resp == ConnectionResult.SUCCESS) {
mGoogleApiClient = new GoogleApiClient.Builder(mContext)
.addApi(ActivityRecognition.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
} else {
Logging.log(Logging.enumLoggingLevel.e, getClass().getName(), "Google play Services are not available.");
}
}
#Override
public void onConnected(Bundle bundle) {
Logging.log(Logging.enumLoggingLevel.d,TAG,"inside onConnected");
Intent intent = new Intent(mContext, ActivityRecognitionIntentService.class);
mpIntent = PendingIntent.getService(mContext, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
ActivityRecognition.ActivityRecognitionApi.requestActivityUpdates(mGoogleApiClient, 1000, mpIntent);
}
#Override
public void onDisconnected() {
Logging.log(Logging.enumLoggingLevel.d,TAG,"inside onDisconnected");
}
#Override
public void onConnectionSuspended(int i) {
Logging.log(Logging.enumLoggingLevel.d,TAG,"inside onConnectionSuspended");
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Logging.log(Logging.enumLoggingLevel.d,TAG,"inside onConnectionFailed");
}
}

Are you missing the call to connect() after the build? The callbacks dont fire unless you call connect.
mGoogleApiClient.connect()
