title: Passing strings between activities in android
body: <p>I have searched quite a few places but i haven't got up with any good solution that worked yet, and i really need help!
  I am making an application that needs to pass a longitude and latitude string from one activity to another.
  How can i do this??? Take a look at my code here: The LocationActivity.java needs to pass the string to the other activity and to another one that i didn't paste into here. And the string that needs to be passed is named: "latLongString"</p>
  
  <p>LocationActivity.java:</p>
  
  <pre><code>import android.R.string;
  import android.app.Activity;
  import android.content.Context;
  import android.content.Intent;
  import android.location.Location;
  import android.location.LocationListener;
  import android.location.LocationManager;
  import android.os.Bundle;
  import android.view.View;
  import android.widget.TextView;
  
  public class LocationActivity extends Activity {
  private String Location;
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      LocationManager locManager;
      locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); 
      locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000L,500.0f, locationListener);
      Location location = locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
      updateWithNewLocation(location);
      if(location != null)                                
      {
          double latitude = location.getLatitude();
      double longitude = location.getLongitude();
      }  
    }
  
  
  private void updateWithNewLocation(Location location) {
      TextView myLocationText = (TextView)findViewById(R.id.LocationWord);
      String latLongString = "";
      if (location != null) {
          double lat = location.getLatitude();
          double lng = location.getLongitude();
          latLongString = "Lat:" + lat + "\nLong:" + lng;
          //This is where i need to pass the string to the other activity
  
      } else {
          latLongString = "No location found";
      }
       myLocationText.setText("Your Current Position is:\n" +
              latLongString);
  }
  
  private final LocationListener locationListener = new LocationListener() {
      public void onLocationChanged(Location location) {
          updateWithNewLocation(location);
      }
  
      public void onProviderDisabled(String provider) {
          updateWithNewLocation(null);
      }

      }
