HI i have been trying to run this code from an example in a book but all i get is is the null value being passed to the variable and so i only get the message as "Your Current Position is : no location found"
The manifest file is as below
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.snooze.android.geopositioning"
android:versionCode="1"
android:versionName="1.0">

android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
The main.xml file is
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"

>
<TextView
android:id="#+id/myLocationText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello"
/>
</LinearLayout>
Lastly is the MainActivity.java
package com.snooze.android.geopositioning;
import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends Activity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LocationManager locationManager;
String context = Context.LOCATION_SERVICE;
locationManager = (LocationManager)getSystemService(context);
String provider = LocationManager.GPS_PROVIDER;
Location location = locationManager.getLastKnownLocation(provider);
updateWithNewLocation(location);
}
public void updateWithNewLocation(Location location)
{
String latLongString;
TextView myLocationText;
myLocationText = (TextView)findViewById(R.id.myLocationText);
if (location != null)
{
double lat = location.getLatitude();
double lng = location.getLongitude();
latLongString = "Lat:" + String.valueOf(lat) + "\nLong:" + String.valueOf(lng);
}
else
{
latLongString = "No location found";
}
myLocationText.setText("Your Current Position is:\n" + latLongString);
}
}
This is my first project so i am unfamiliar with a few of the workings but i copied everything as the book said but it does not work. Have tried various things on many sites, as well as answers from this forum....but to no avail.
I am using Eclipse and have added tried to run it on and AVD with Android 2.2 as well as for Google APIs.
What i think is that the co-ordinates are not being passed to the variables.
I had posted as a new user but was not able to comment on it so i have asked it again.
Lukas Kunth, chaitanya and wareninja thanks for your answers.
Apologies for the duplication.
Please help
You are missing the LocationListener without which your application cannot receive location updates.
Here is an excellent blog on GPS Location fetching..

For getting direction and distance from Google you have to do following:
Write this code on direction button's click listener or anywhere from that you want to show direction and distance.
String uri = "http://maps.google.com/maps?saddr="
+ source_latitude + "," + source_longitude + "&daddr="
+ destination_latitude + ","
+ destination_longitude;
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse(uri));
intent.setClassName("com.google.android.apps.maps",
"com.google.android.maps.MapsActivity");
startActivity(intent);
i am creating a android which shows the user location with Google Maps through gps. when i run my program i have the following errors.
activity_main cannot be resolved or is not a field, displayMap cannot be resolved or is not a field
main cannot be resolved or is not a field. at first this error did not appear but after i save or clean my project, it appears
i have change the displayMap and save, clean my project in strings and xml file. but the error is still there.
Attribute "name" bound to namespace "http://schemas.android.com/apk/res/android" was already specified for element "meta-data" in my android manifest
Parser exception for /MyAppName/AndroidManifest.xml: Attribute "name" bound to namespace "http://schemas.android.com/apk/res/android" was already specified for element "meta-data". the resource for this is my ApplicationNameApp(my project name)
does that means i must change the "name" under meta data?

i have added google play services as a project, google-play-services_lib appear as a seperate project folder then my application in eclipse. then i add to my libarary by Project -> Properties -> Android -> Library, Add -> google-play-services_lib
Change this

android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyAZUoTQoHQwP25j0L_hTIUsXjxWmkFi3vg"
android:name="com.google.android.gms.version"

Remove
import android.R;
Instead you need
import com.example.studenthealthapp.R;
But if its in the same package then there is no need for import.
Also if you have errors in your resources files R.java will not be generated. So if any errors fix them and clean and build project.
remove import android.R;
and import your package name.R file
#Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
if (resultCode == ConnectionResult.SUCCESS){
Toast.makeText(getApplicationContext(),
"isGooglePlayServicesAvailable SUCCESS",
Toast.LENGTH_LONG).show();
}else{
GooglePlayServicesUtil.getErrorDialog(resultCode, this, RQS_GooglePlayServices);
}
}
I create simple android apps which show location of device but when I run in emulator it show error in run the apps.

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Location loc =
manager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
textView.setText("latitude: " + loc.getLatitude()
+ "\nlongitude: " + loc.getLongitude());
} }

Error is:
The application loc has stopped unexpected.
You must have your class implement LocationListener and call manager.requestLocationUpdates() in order to obtain location information. See further details at http://developer.android.com/training/location/receive-location-updates.html
Here goes: I've spent all night scouring the internet, especially StackOverflow, trying to figure out why I can't get basic Location Services working in Android. I have tried in a variety of emulated environments, from Android 1.6 up to Android 4, all with GPS services emulated, as well as on an actual Android 2.2.2 Device. Location is always returned as null, I've tried at least seven different downloadable sample projects, using them verbatim, and getting the same results.
Obviously, I'm missing something key. If anyone could point out what I'm doing wrong, it would be greatly appreciated.

add this to onCreate() function,
locmgr.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,10000.0f,onLocationChange);
If onLocationChanged() isn't even being called, even with sample projects, then I don't think "location is always null" is an accurate description of the problem. onLocationChanged() is only called when the location changes. So it sounds like you are (a) not injecting mock locations or otherwise driving the location engine when using the emulator, and (b) not moving around enough on the real device. I suggest loading a sample project onto the real device, going outside, and moving around some (several 10s of meters). Put some breadcrumbs in the onLocationChanged() method (in the sample project) to verify that it's being called.
I'm new to android
I'm trying make a simple app in android with google map, but when I run it in emulator look error

android:apiKey="0Qe1BE05sZZFeWkfqemBVn-tw_Y_Kc9E40HpY-w" />
</RelativeLayout>
But when I run this program I got this error
The Application MapGoogle (process com.jol.android.Mapgoogle) has stopped unexpectedly. Please try again.
Why like this? Please help me. Thank you, mate.
Try this
<uses-permission android:name="android.permission.INTERNET"></uses-permission>

You have several problems, the main one being the line:
RelativeLayout linearLayout = (RelativeLayout) findViewById(R.id.mapview);
It's an illegal cast and it does nothing - get rid of it!
As a matter of style your package should be all lower case, make it
package com.jol.android.mapgoogle;
Make sure you compilation unit is called Googlemaps.java and that it matches the class name.
As other posters have pointed out, you need certain permissions in the manifest. This manifest should work and match the other changes I have mentioned.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.jol.android.mapgoogle"

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
<uses-sdk android:minSdkVersion="9" />

</activity>
<uses-library

.
You need to add following tag in your manifest file
<application >
<activity>
<uses-library android:name="com.google.android.maps" />
</activity>
</application>
Put this in the manifest:
<uses-permission android:name="android.permission.INTERNET">
