it doesn't give me the country name

[shawn peter]

this is my main class.it shows me the longitude & latitude.

package com.visini.android;

import java.util.List;

import android.app.Activity;
import android.location.Address;
import android.location.Criteria;
import android.location.Geocoder;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.widget.TextView;

	
	
public class LocationActivity extends Activity implements LocationListener {
	
	private LocationManager locationManager;
	private String locationdetails;
	
    /** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
	    super.onCreate(savedInstanceState);
	    setContentView(R.layout.main);
	    
	    TextView locationdetailstextview = (TextView)findViewById(R.id.locationDetailstextView);
	    
	    locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
	    
	    //Get the best provider  for the criteria
	    
	    Criteria criteria = new Criteria();
	    criteria.setPowerRequirement(Criteria.POWER_LOW);
	    criteria.setAccuracy(Criteria.ACCURACY_COARSE);
	    
	    String bestprovider = locationManager.getBestProvider(criteria,false);
	    
	    Location lastknownlocation = locationManager.getLastKnownLocation(bestprovider);
	    
	    //Location lastknownlocation = locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER);
	
	    if (lastknownlocation != null){
	    	  	locationdetails = "Last Know Location:----- Latitude: "+lastknownlocation.getLatitude() +"Longitude :"+lastknownlocation.getLongitude();
	    locationdetailstextview.setText(locationdetails);
	    }
	    
	    locationManager.requestLocationUpdates(bestprovider,5000, 0.2f, this);
	    
	   // locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,5000, 0.2f, this);
	    
	}

	@Override
	public void onLocationChanged(Location location) {
		
		try{
		// TODO Auto-generated method stub
	    TextView locationdetailstextview = (TextView)findViewById(R.id.locationDetailstextView);
	 	locationdetails += "\n Current Location:----- Latitude: "+location.getLatitude() +"Longitude :"+location.getLongitude();
	    locationdetailstextview.setText(locationdetails);
	    
	    //get the address using google map
	    Geocoder geocoder = new Geocoder(this);
	    List<Address> addresses = geocoder.getFromLocation(location.getLatitude(),location.getLongitude(),1);
	    
	    
	    for (Address address: addresses){
	    	
	    	locationdetails += "Address is "+address.getAddressLine(0)+" ,"+address.getCountryName();
	    	}
		}
		catch(Exception e){
			System.out.println(e.toString());
		}
	}

	@Override
	public void onProviderDisabled(String arg0) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void onProviderEnabled(String arg0) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
		// TODO Auto-generated method stub
		
	}
}

it is working fine.but the thing is that when i run this programm in my phone it gives me that current location latitude and longitude.

but it doesn't give me the country name.I don't know why ?
can anyone tell me the reason ?

[Tim Moores]

I assume there is code somewhere that prints out locationdetails after the geoCoder has been called? Or are you relying on onLocationChanged being called again with another location update?

[Naishadh Parmar]

But you didn't call locationdetailstextview.setText() method after getting the country!!!

[shawn peter]

I change the code.here is my java class.i have added a settext after getCountry line.

package com.visini.android;

import java.util.List;

import android.app.Activity;
import android.location.Address;
import android.location.Criteria;
import android.location.Geocoder;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.widget.TextView;

	
	
public class LocationActivity extends Activity implements LocationListener {
	
	private LocationManager locationManager;
	private String locationdetails;
	
	
    /** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
	    super.onCreate(savedInstanceState);
	    setContentView(R.layout.main);
	    
	    TextView locationdetailstextview = (TextView)findViewById(R.id.locationDetailstextView);
	    
	    locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
	    
	    //Get the best provider  for the criteria
	    
	    Criteria criteria = new Criteria();
	    criteria.setPowerRequirement(Criteria.POWER_LOW);
	    criteria.setAccuracy(Criteria.ACCURACY_COARSE);
	    
	    String bestprovider = locationManager.getBestProvider(criteria,false);
	    
	    Location lastknownlocation = locationManager.getLastKnownLocation(bestprovider);
	    
	    //Location lastknownlocation = locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER);
	
	    if (lastknownlocation != null){
	    	  	locationdetails = "Last Know Location:----- Latitude: "+lastknownlocation.getLatitude()*1e4  +"Longitude :"+lastknownlocation.getLongitude()*1e4;
	    	  	
	    locationdetailstextview.setText(locationdetails);
	    }
	    
	    locationManager.requestLocationUpdates(bestprovider,5000, 0.2f, this);
	    
	   // locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,5000, 0.2f, this);
	    
	}

	@Override
	public void onLocationChanged(Location location) {
		
		try{
		// TODO Auto-generated method stub
	    TextView locationdetailstextview = (TextView)findViewById(R.id.locationDetailstextView);
	 	locationdetails += "\n Current Location:----- Latitude: "+location.getLatitude()*1e6 +"Longitude :"+location.getLongitude()*1e6 ;
	    locationdetailstextview.setText(locationdetails);
	    
	    //get the address using google map
	    Geocoder geocoder = new Geocoder(this);
	    List<Address> addresses = geocoder.getFromLocation(location.getLatitude(),location.getLongitude(),1);
	    
	    
	    for (Address address: addresses){
	    	
	    	locationdetails += "Address is "+address.getAddressLine(0)+" ,"+address.getCountryName();
	    	}
		locationdetailstextview.setText(locationdetails);
		}
		
		
		catch(Exception e){
			System.out.println(e.toString());
		}
	}

	@Override
	public void onProviderDisabled(String arg0) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void onProviderEnabled(String arg0) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
		// TODO Auto-generated method stub
		
	}
}

This is my main xml file

<?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"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    
    />
<TextView android:layout_width="wrap_content" android:id="@+id/locationDetailstextView" android:layout_height="wrap_content" ></TextView>
</LinearLayout>

still no prints country name.
