Here is my code for MainActivity.java
package com.example.com.draft1;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v4.app.NavUtils;
import android.view.KeyEvent;
import com.google.android.maps.MapController;
public class MainActivity extends MapActivity {
MapView mapView;
MapController mc;
GeoPoint p;
String coordinates[]={"1.352566007","103.78921587"};
double lat=Double.parseDouble(coordinates[0]);
double lng=Double.parseDouble(coordinates[1]);
@Override
public void onCreate(Bundle savedInstanceState) {
p=new GeoPoint((int)(lat*1E6),(int)(lng*1E6));
mapView=(MapView)findViewById(R.id.mapView);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mc.setCenter(p);
//mc.setZoom(13);
//mapView.invalidate();
//myMapController.setCenter(new GeoPoint((int)(lat*1E6),(int)(lng*1E6)));
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
@Override
protected boolean isRouteDisplayed()
{
//adssad
return false;
}
}
Now , the above code leads to a force close .
