    <p>i have this code that detects your walking speed and it records the latitude and longitude and your walking speed or if your standing not walking in an sqlite tabel then it should call the table and send them to a server using httpconnect </p> <p>for some reason its not sending the info to the server and also it crashes after a while what is causing the problem and i read somewhere online that i should make the code as a service can you please tell me how to fix the code and is there any problems with the timer</p> <p>Note: I have no errors in the code</p> <p>thank you in advance</p> <pre><code> class WalkingData{ public double lng=0.0; public double lat=0.0; public long gpsTime=0; public double Walking=0.0; public WalkingData (double ilng, double ilat, long iGPSTime, double iWalking){ lng=ilng; lat=ilat; gpsTime=iGPSTime; Walking=iWalking; } } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); LocationManager locationManager; String context = Context.LOCATION_SERVICE; locationManager = (LocationManager) getSystemService(context); Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_FINE); criteria.setAltitudeRequired(false); criteria.setBearingRequired(false); criteria.setCostAllowed(true); criteria.setPowerRequirement(Criteria.POWER_LOW); String provider = locationManager.getBestProvider(criteria, true); Location location = locationManager.getLastKnownLocation(provider); updateWithNewLocation(location); locationManager.requestLocationUpdates(provider, 2000, 10, locationListener); } private final LocationListener locationListener = new LocationListener() { public void onLocationChanged(Location location) { updateWithNewLocation(location); } public void onProviderDisabled(String provider) { updateWithNewLocation(null); } public void onProviderEnabled(String provider) { } public void onStatusChanged(String provider, int status, Bundle extras) { } }; private void updateWithNewLocation(Location location) { String latLongString; TextView myLocationText; myLocationText = (TextView) findViewById(R.id.myLocationText); //String addressString = "No address found"; if (location != null) { double lat = location.getLatitude(); double lng = location.getLongitude(); latLongString = "Lat:" + lat + "\nLong:" + lng; MyWalk =(double)location.getSpeed(); MyGPSTime = location.getTime(); long currentTimestamp = System.currentTimeMillis(); myLocationText.setText("Your Current Walk: " + (MyWalk) +"\nYour Current Position is: " + latLongString + "\n" + "Time is: " + currentTimestamp+"\n\n"); trakingWalking (MyWalk, lat, lng, MyGPSTime); } else { latLongString = "No location found"; } } public void trakingWalking (double Walking, double lat, double lng, long GPSTime) { final double ChangedWalking = Walking; final double ChangedLat = lat; final double ChangedLng = lng; final long ChangedGPSTime = GPSTime; Timer updateTimer = new Timer("pedometer"); updateTimer.scheduleAtFixedRate(new TimerTask() { public void run() { checkWalking(ChangedWalking, ChangedLat, ChangedLng, ChangedGPSTime); } }, 0, WalkingSampleRate); } private void checkWalking( double ChangedWalking1, double ChangedLat1, double ChangedLng1, long ChangedGPSTime1) { final double ChangedWalking2 = ChangedWalking1; final double ChangedLat2 = ChangedLat1; final double ChangedLng2 = ChangedLng1; final long ChangedGPSTime2 = ChangedGPSTime1; WalkingHandler.post(new Runnable() { public void run() { if(WalkingState==0){ //TODO Log.v("log_tag", "+-+-+-+-+-+-+-+-+- you are standing"); } //state = 0 else(WalkingState==1){ StoreWalking(); Sticket(); } } }); } public void Sticket(){ Log.v("log_tag", "????????????????????????????????

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
