GPS doesn't search on my Android

GPS doesn't search on my Android - android

I'm new on android programation and I have a problem with my aplication.
My Gps just doesn't search for location, or anything else.
And yes, my GPS is tunned on.
The manifest cointains the permitions:
ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION.
Could somebody help me?

I normally don't do this, but I almost have to go.
This is the code I use, it works. (just put this in a new project).
I didn't clean it, because I ripped it from my other project, but it does work, when you make a new project and just copy/paste this.:

locationResult.gotLocation(net_loc);
return;
}
locationResult.gotLocation(null);
}
}
public static abstract class LocationResult{
public abstract void gotLocation(Location location);
}
}
Also add this in manifest:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
No time to explain now, maybe tomorrow if you still need it.
It prints the latitude and longitude in your logcat.

Unable to get location from GPS?

I am trying to get the location from the GPS but not able to get it. this is because the location is accessed by the Network provider.
If I am commenting all the code of network provider then the GPS location returns null.
I have tried so much, but unable to resolve this.
If anybody can help then it will be great help for me.
I am using this link for the reference..

You can use the below service for getting gps.just invoke this service at the begining.
public class MyService extends Service {
LocationManager locationManager;
#Override
public void onCreate() {
//
// TODO Auto-generated method stub
String context = Context.LOCATION_SERVICE;
locationManager = (LocationManager) getSystemService(context);
/** Criteria for selecting best provider */
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setAltitudeRequired(false);
criteria.setBearingRequired(false);
criteria.setCostAllowed(true);
criteria.setPowerRequirement(Criteria.POWER_LOW);
/** Passing criteria and select only enabled provider */
String provider = locationManager.getBestProvider(criteria, true);
Location location = locationManager.getLastKnownLocation(provider);
/** calls the Location Listner */
locationManager.requestLocationUpdates(provider, 500, 0,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)
{
System.out.println("+++++++++++++++++++SASI+++++++++++++++++++++++++++++++++++++++++");
String latLongString, addressString = null;
double lat = 0, lng = 0;
if (location != null) {
lat = location.getLatitude();
lng = location.getLongitude();
//latLongString = "Lat:" + lat + "\nLong: " + lng;
/** Getting Address */
} else {
latLongString = "No location found";
addressString = "No location found";
}
//System.out.println("###########" + addressString + lat + lng);
SearchDeals.latPoint=location.getLatitude();
SearchDeals.lngPoint=location.getLongitude();
Deals_route.sourcelati=location.getLatitude();
Deals_route.sourcelong=location.getLongitude();
}
#Override
public void onDestroy() {
super.onDestroy();
//
//Toast.makeText(this, "GPS Service Destroyed", Toast.LENGTH_LONG).show();
locationManager.removeUpdates(locationListener);
System.out.println("########### inside ONDESTROY GPS listener removed");
}
#Override
public int onStartCommand(Intent intent, int flags, int startId)
{
//
Log.v("StartServiceAtBoot", "StartAtBootService -- onStartCommand()");
//Toast.makeText(this, "Service started", Toast.LENGTH_LONG).show();
// We want this service to continue running until it is explicitly
// stopped, so return sticky.

I've just tested the above code on my device and everything is working smoothly, not sure what is the problem at your end.
Important notes:
Please make sure you have the permission to access GPS location in your manifest file
<uses-permission
android:name="android.permission.ACCESS_FINE_LOCATION"/>
The code may not work properly on the emulator , better test on actual device. if you don't have access to one , please checkout the DMMS Emulator Control to generate location data
Edit:
you need to commit out the Location data related to Network Provider.
and Also remove the textView.setText from your LocationResult object because textView is null. so the fixes:
getLocation(Location location) {
.........
String loc = "Lattitude: "+location.getLatitude()+" longi "+location.getLongitude()+" Accur "+location.getAccuracy()+" Time "+location.getTime() +" "+location.getProvider();
Log.i("Log",loc);
Toast.makeText(MainActivity.this, loc, Toast.LENGTH_LONG).show();
}
and comment out the network code from your MyLocation class
// if(network_enabled)
// lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListenerNetwork);

Not able to get Longitude and Latitude in android

Even though the GPS is on and network is full sometime i am not able to get the lagitude and latitude values of current location but sometimes i am able to get the values sometimes its showing latitude and longitude as 0....can someone help me.

I would suggest to try this code, I use this code too, and works like a charm:
package com.fitness24.my24;
import java.util.Timer;
import java.util.TimerTask;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;

public class MyLocation {
Timer timer1;
LocationManager lm;
LocationResult locationResult;
boolean gps_enabled=false;
boolean network_enabled=false;
public boolean getLocation(Context context, LocationResult result)
{
//I use LocationResult callback class to pass location value from MyLocation to user code.
locationResult=result;
if(lm==null)
lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
//exceptions will be thrown if provider is not permitted.
try{gps_enabled=lm.isProviderEnabled(LocationManager.GPS_PROVIDER);}catch(Exception ex){}
try{network_enabled=lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);}catch(Exception ex){}
//don't start listeners if no provider is enabled
if(!gps_enabled && !network_enabled){
System.out.println("gps and/or network disabled");
return false;
}
if(gps_enabled){
System.out.println("gps enabled");
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListenerGps);
}
if(network_enabled)
System.out.println("network enabled");
lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListenerNetwork);
timer1=new Timer();
timer1.schedule(new GetLastLocation(), 25000);
return true;
}
LocationListener locationListenerGps = new LocationListener() {
public void onLocationChanged(Location location) {
timer1.cancel();
locationResult.gotLocation(location);
lm.removeUpdates(this);
lm.removeUpdates(locationListenerNetwork);
}
public void onProviderDisabled(String provider) {}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
};
LocationListener locationListenerNetwork = new LocationListener() {
public void onLocationChanged(Location location) {
timer1.cancel();
locationResult.gotLocation(location);
lm.removeUpdates(this);
lm.removeUpdates(locationListenerGps);
}
public void onProviderDisabled(String provider) {}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
};
class GetLastLocation extends TimerTask {
#Override
public void run() {
lm.removeUpdates(locationListenerGps);
lm.removeUpdates(locationListenerNetwork);
Location net_loc=null, gps_loc=null;
if(gps_enabled)
gps_loc=lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if(network_enabled)
net_loc=lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
//if there are both values use the latest one
if(gps_loc!=null && net_loc!=null){
if(gps_loc.getTime()>net_loc.getTime())
locationResult.gotLocation(gps_loc);
else
locationResult.gotLocation(net_loc);
return;
}
if(gps_loc!=null){
locationResult.gotLocation(gps_loc);
return;
}
if(net_loc!=null){
locationResult.gotLocation(net_loc);
return;
}
locationResult.gotLocation(null);
}
}
public static abstract class LocationResult{
public abstract void gotLocation(Location location);
}
}
Then in your main class:
import com.fitness24.my24.MyLocation.LocationResult;
import android.location.Location;
Then also add this in your main, to call/recieve the gps:
private void locationClick() {
myLocation.getLocation(this, locationResult);
}
public LocationResult locationResult = new LocationResult() {
public void gotLocation(final Location location) {
try {
double lat = location.getLatitude();
double lng = location.getLongitude();
if (lat != 0.0 && lng != 0.0) {
String sLat;
String sLng;
sLat = Double.toString(lat);
sLng = Double.toString(lng);
gps_location = sLat+" "+sLng;
Toast.makeText(getBaseContext(), "We got gps location!", Toast.LENGTH_LONG)
.show();
}
}catch (Exception e) {
}
}
};
this locationClick() is on onClick event of my button (the button to call/recieve gps info)
Also, don't forget to add this in your manifest:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

It is Simple,
LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
double longitude = location.getLongitude();
double latitude = location.getLatitude();
And dont forget to use this Permission
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Add the following permissions in your manifest:
<uses-permission android:name="android.permission.ACCESS_GPS"/>

Current user location is not retrieving

This is my last question about gps
Getting 0.0 for latitude and longitude while showing current location in map
Now here is the code I'm using to get the user's current location.
LocationManager mlocManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Criteria crta = new Criteria();
crta.setAccuracy(Criteria.ACCURACY_FINE);
crta.setAltitudeRequired(false);
crta.setBearingRequired(false);
crta.setCostAllowed(true);
crta.setPowerRequirement(Criteria.POWER_LOW);
String provider = mlocManager.getBestProvider(crta, true);
Location loc = null;
if (provider != null) {
loc = mlocManager.getLastKnownLocation(provider);
}
LocationListener mlocListener = new MyLocationListener();
mlocListener.onLocationChanged(loc);
mlocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
2000, 10, mlocListener);
public class MyLocationListener implements LocationListener{
public MyLocationListener() {
}
#Override
public void onLocationChanged(Location loc) {
if (null != loc) {
String Text = "Your current location is: \n" + "Latitude = \n"
+ loc.getLatitude() + "\nLongitude = \n" + loc.getLongitude();
Toast.makeText(getApplicationContext(),Text,Toast.LENGTH_SHORT).show();
GeoPoint myGeoPoint = new GeoPoint((int)(loc.getLatitude()*1E6),(int)(loc.getLongitude()*1E6));
mpc.animateTo(myGeoPoint);
mpc.setZoom(10);
objMapView.invalidate();
}
}
#Override
public void onProviderDisabled(String provider){
Toast.makeText(getApplicationContext(), "gps disabled",Toast.LENGTH_SHORT).show();
}
#Override
public void onProviderEnabled(String provider) {
Toast.makeText(getApplicationContext(), "gps enabled",Toast.LENGTH_SHORT).show();
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
}
Now the problem I'm facing is, it is not showing me the current location when the gps is turned on. The loc object , loc = mlocManager.getLastKnownLocation(provider); always returns null. I got the value for provider as gps.
But if I turn of my gps connection, the same loc object will have relevant information and it works partiall correct. That means, it gives me the nearest location. I mean the full city location where I am sitting.
But if I on my gps connection, it does not give me even the city location also, does not enters if loop only inside location listener class. I am not getting what is going wrong here.
Any one can tell me how to solve it?
Update:
This is the value I get for loc object if my gps is off
Location[mProvider=network,mTime=1331718353322,mLatitude=12.9053401,mLongitude=74.8359128,mHasAltitude=false,mAltitude=0.0,mHasSpeed=false,mSpeed=0.0,mHasBearing=false,mBearing=0.0,mHasAccuracy=true,mAccuracy=36.0,mExtras=Bundle[mParcelledData.dataSize=148]].
But if the gps is on, loca return null

First of all I'm not familiar with the Android location API, but did you try the GPS outside? Since GPS doesn't work inside buildings, it's pretty hard to retrieve the location of your mobile device using only your GPS. When indoors, typically your "GPS" position is determined using your WiFi acces point connection instead.

grab the lat and lng

So i found this script to get the best location and have added it to a app. When i call for the location it just gives a random number after the package name (com.android.package.currentactivity$1#randomcode)
MyLocation myLocation = new MyLocation();
private void locationClick() {
myLocation.getLocation(this, locationResult));
}
public LocationResult locationResult = new LocationResult(){
#Override
public void gotLocation(final Location location){
//Got the location!
});
}
};
and the MyLocation.java
import java.util.Timer;
import java.util.TimerTask;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
public class MyLocation {
Timer timer1;
LocationManager lm;
LocationResult locationResult;
boolean gps_enabled=false;
boolean network_enabled=false;
public boolean getLocation(Context context, LocationResult result)
{
//I use LocationResult callback class to pass location value from MyLocation to user code.
locationResult=result;
if(lm==null)
lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
//exceptions will be thrown if provider is not permitted.
try{gps_enabled=lm.isProviderEnabled(LocationManager.GPS_PROVIDER);}catch(Exception ex){}
try{network_enabled=lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);}catch(Exception ex){}
//don't start listeners if no provider is enabled
if(!gps_enabled && !network_enabled)
return false;
if(gps_enabled)
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListenerGps);
if(network_enabled)
lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListenerNetwork);
timer1=new Timer();
timer1.schedule(new GetLastLocation(), 20000);
return true;
}
LocationListener locationListenerGps = new LocationListener() {
public void onLocationChanged(Location location) {
timer1.cancel();
locationResult.gotLocation(location);
lm.removeUpdates(this);
lm.removeUpdates(locationListenerNetwork);
}
public void onProviderDisabled(String provider) {}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
};
LocationListener locationListenerNetwork = new LocationListener() {
public void onLocationChanged(Location location) {
timer1.cancel();
locationResult.gotLocation(location);
lm.removeUpdates(this);
lm.removeUpdates(locationListenerGps);
}

public void onProviderEnabled(String provider) {}

};

if(gps_enabled)

if(network_enabled)

//if there are both values use the latest one
if(gps_loc!=null && net_loc!=null){
if(gps_loc.getTime()>net_loc.getTime())
locationResult.gotLocation(gps_loc);
else
locationResult.gotLocation(net_loc);
return;
}
if(gps_loc!=null){
locationResult.gotLocation(gps_loc);
return;
}
if(net_loc!=null){
locationResult.gotLocation(net_loc);
return;

locationResult.gotLocation(null);

public static abstract class LocationResult{
public abstract void gotLocation(Location location);
}
}
What im trying to get is the lat and lng so i can use is in my activity.

You will need to be more explicit on where do you get that string, so we can help you pinpoint the issue, but that string represent your Activity instance as a String.
public String toString ()
Since: API Level 1
Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:
getClass().getName() + '#' + Integer.toHexString(hashCode())
See Writing a useful toString method if you intend implementing your own toString method.
Returns a printable representation of this object.
Edit: It's not your activity, but an inner class inside it (this is told by the $1 part). Perhaps the MyLocation instance?

You need to add one or both of these to your manifest.xml:
<uses-permission
android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission
android:name="android.permission.ACCESS_FINE_LOCATION" />
This is the bulk of my location code. Use it. It works.:
/**************************************************************************
* helper functions for starting/stopping monitoring of Location changes below
**************************************************************************/
public void startListening() {
if (networkLocationListener == null && gpsLocationListener == null) {
// make new listeners
networkLocationListener = new BegetLocationListener(LocationManager.NETWORK_PROVIDER);
gpsLocationListener = new BegetLocationListener(LocationManager.GPS_PROVIDER);
// request very rapid updates initially. after first update, we'll put them back down to a much lower frequency
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 60000, 200, networkLocationListener);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 60000, 200, gpsLocationListener);
}
Location networkLocation = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (networkLocation != null) {
appModel.setLocation(networkLocation);
}
updateDistances(appModel.getLocation());
}
private void stopListening() {
if (networkLocationListener != null)
locationManager.removeUpdates(networkLocationListener);
if (gpsLocationListener != null)
locationManager.removeUpdates(gpsLocationListener);
gpsLocationListener = null;
networkLocationListener = null;
}
private void handleListenerDisabled(BegetLocationListener listener) {
if (!appModel.getFlags().hasLocationMessageBeenDisplayed()) {
if (networkLocationListener.locationStatusKnown && gpsLocationListener.locationStatusKnown) {
if (networkLocationListener.locationIsEnabled && !gpsLocationListener.locationIsEnabled) {
showAlert(YES_NETWORK_NO_GPS_MSG, BaseActivity.DIALOG_LOCATION);
appModel.getFlags().setLocationMessageDisplayed(true);
} else {
showAlert(NO_NETWORK_NO_GPS_MSG, BaseActivity.DIALOG_LOCATION);
appModel.getFlags().setLocationMessageDisplayed(true);
}
}
}
}
private void handleLocationChanged(Location location) {
if (location == null) {
return;
}
if (isBetterLocation(location, appModel.getLocation())) {
appModel.setLocation(location);
stopListening();
}
}
private class BegetLocationListener implements LocationListener {
private String provider = "";
private boolean locationIsEnabled = true;
private boolean locationStatusKnown = true;
public BegetLocationListener(String provider) {
this.provider = provider;
}
#Override
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
handleLocationChanged(location);
}
public void onStatusChanged(String provider, int status, Bundle extras) {
}
public void onProviderEnabled(String provider) {
startListening();
}
public void onProviderDisabled(String provider) {
locationStatusKnown = true;
locationIsEnabled = false;
handleListenerDisabled(this);
}
}
Obviously you'll want to remove the appModel stuff and the custom dialog stuff.

location problem

Hi to all im new to android and i have a small problem and i would really appreciate if someone can help me
first im trying to show all available location providers and its not working and 2nd when ever i run the it i don't get any location information from the best available provider (i have my wifi and network providers on)
thanks in advance

I had also same problem before, after searching a lot...came to solution and makes it possibale to get instant location of device through following code...actuallu we can not have gps responce instantly so we can have our location on the basis of cell-tower or wifi. so enable one of them to get instant location of your device..
