Get GPS Location instantly via Android app

Get GPS Location instantly via Android app - android

all. I am writing an android app about GPS locations.
I tried it on emulator and entered the latitude and longitude manually, and it worked fine.
However, my problem is: on the real device, in debugging mode, to go the next class by using intent can only be achieved when location is changed. If I start the app directly, I can see the blinking GPS icon, but the app will only stay here, and won't start the next activity. It seems that the variables in the onLocationChanged() will never be changed.
I have heard that to get the location instantly is to use the getLastKnownLocation() method. But I failed to get where I should use it.
Here is the class of how I use the LocationManager to get the locations.
Is there any solutions? I am quite confused. Thank you very much!!

The getLastKnownLocation method does not trigger an onLocationChanged event. One way to refactor your code would be to move the logic that acts on a Location to a separate method and then call that method both after you call getLastKnownLocation, and from your onLocationChanged method.
Bear in mind that there is no guarantee that getLastKnownLocation will provide a meaningful Location, since you the device might have moved since the last location update.
Example code:
public void onCreate(Bundle savedInstanceState){
....
String provider = LocationManager.GPS_PROVIDER;
Location location = locationManager.getLastKnownLocation(provider);
updateLocation(location);
}
public class MyLocationUpdater implements LocationListener{ //change location interface
#Override
public void onLocationChanged(Location location) {
updateLocation(location);
}
...
}
void updateLocation(Location location) {
Double lat = location.getLatitude();
Double lon = location.getLongitude();
// the rest of the code from onLocationChanged
}

getLastKnownLocation() is faster after a connection has been established with the GPS satellite. For the first time, it will return null, or no value till no connection is established.
You can add a GpsListener to know when the location is obtained. Search about "how to get a gps fix" and you might get answer to your question

I have same problem before..but I have got the solution..this is the simplest way to get location instantly.
public class LocationFinder extends Activity {
TextView textView1;
Location currentLocation;
double currentLatitude,currentLongitude;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
textView1 = (TextView) findViewById(R.id.textView1);
Log.i("########## Inside LocationFinder onCreate", "LocationFinder onCreate");
FindLocation();
}
public void FindLocation() {
LocationManager locationManager = (LocationManager) this
.getSystemService(Context.LOCATION_SERVICE);
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
updateLocation(location);
Toast.makeText(
LocationFinder.this,
String.valueOf(currentLatitude) + "\n"
+ String.valueOf(currentLongitude), 5000)
.show();
}
public void onStatusChanged(String provider, int status,
Bundle extras) {
}
public void onProviderEnabled(String provider) {
}
public void onProviderDisabled(String provider) {
}
};
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
}
void updateLocation(Location location) {
currentLocation = location;
currentLatitude = currentLocation.getLatitude();
currentLongitude = currentLocation.getLongitude();
textView1.setText(String.valueOf(currentLatitude) + "\n"
+ String.valueOf(currentLongitude));
}
}

This is the code i have use it for finding the device location with the help of latitude and longitude and we also call getLastLocationUpdate in this code.
I hope this is very help full to you.

Here is your problem: You are passing string values through intent when you expect the doubles in your second...
Intent intent = new Intent(MainActivity.this, FinishActivity.class);
intent.putExtra("dist","value");
intent.putExtra("time","durationValue");
startActivity(intent);

[EDIT] I assume you have 2 EditTexts to allow the user to enter the data. Lets say they are editText1 &editText2.
The EditTexts hold Strings so you need to convert/cast them.
Double value=Double.valueOf(editText1.getText().toString());
Double durationValue=Double.valueOf(editText2.getText().toString());
Also Make sure that you enter only digits in the EditTexts.
In your FirstActivity you are passing Strings instead of Doubles.
So instead of that you should use it like this:
intent.putExtra("dist",value);
intent.putExtra("time",durationValue);
Just omit the double Quotes " ".
notice that value and durationValue are must be Doubles in your code.
Hope it Helps.

This is the my code i am using this for getting user current location.
Read it carefully the check what the mistake you have done in your code.
and also check all the permission in mainfest file related to gps.
<uses-permission android:name="android.permission.ACCESS_GPS" />
<uses-permission android:name="android.permission.ACCESS_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
I hope this is help.

private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 1; // in Meters
change this to 0 ....

Just extends the GpsStatus.Listener in your activity.
like as following:
ublic class MyActivity implements LocationListener,
GpsStatus.Listener
and check your permission:

android gps app for traffic application

I've currently finished learning the basics of android development and am trying to learn to make an android gps app in smartphones for my traffic system project. Not so very good yet in doing complicated codes. Please advise some resources or tutorials which will greatly help me to make this app.
- the app will send gps locations( lat & longitude and time ) via sms every 10 seconds once it approach a specific road section ( can be like 0.5 km length of road)
- if the phone passed that specific road section it will stop sending its locations

Why are you using the sms service to send the location? try using the webservice.
To implement this app you has to use the LocationManager and LocationListener libraries.
You can start by creating a gps listening class implementing the LocationListener, like the one shown below
public class CTLocationListener implements LocationListener{
#Override
public void onLocationChanged(Location location) {
Log.w("LOCATION CHANGED", ""+location);
if(location != null) {
Constants.LATTITUDE = location.getLatitude();
Constants.LONGITUDE = location.getLongitude();
Constants.kAccuracy = location.getAccuracy();
Constants.ALTITUDE_VALUE = location.getAltitude();
}
}
#Override
public void onProviderDisabled(String provider) {
Log.i("PROVIDER", "DISABLED:"+provider);
}
#Override
public void onProviderEnabled(String provider) {
Log.i("PROVIDER", "ENABLED:"+provider);
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.i("EXTRAS", ""+extras);
Log.i("Provider status", ""+status);
}
}
Here I'm storing the updated locations on the Constants file. Start a sheduler that checks the locations periodically and start sending messages if they match your required locations.
To trigger the gps you can use
LocationListener locationListener = new CTLocationListener();
LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 1.0f, locationListener);
The scheduler you need is a timertask. This can be implemented as
public class showAccuracy extends TimerTask {
#Override
public void run() {
ghandler.post(new Runnable() {
#Override
public void run() {
if((Constants.Latitude == yourlatitude) && .....) {
}
}
});
}
}

public class HomeActivity extends Activity implements LocationListener{
public static Context mContext;
private double latitude, longitude;
public LocationManager mLocManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
mContext=this;
super.onCreate(savedInstanceState);
setContentView(R.layout.homelayout);
mLocManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
mLocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
this);
mLocManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0,
0, this);
locationUpdate();

This is the code use for getting latitude and longitude or the device and also got the all information about the lat long using get address function .
here some other URL is very use full to you.

Gps location in android

I am using LocationManager to get the current location in android.for that ,i have used
mlocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mlocListener);
GPS_PROVIDER as a service provide.while executing it returns null and shows the following in the log cat continuously.

I am using this code for getting latitude and longitude of current location of the user.
You should read it then convert it according to your requirement and also add the permission of using GPS in manifast file of your project.It is.
<uses-permission android:name="android.permission.ACCESS_GPS" />
<uses-permission android:name="android.permission.ACCESS_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
I hope this is very helpful to you.

Test this Code and then Tel me if u have any Success!
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){ }
};
and use following Permissions:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
this ones Working fine on ma side.. you should try all this!
