Hello and Good Morning,
I was doing examples of MapView to finish my templates for the
AndCooper Build tool and found that no matter what example I try I get
the same exception errors in SDK 1.5r3..
First lets head off the obvious.
-No widgets are present in the example.
-Simple class:
package com.mobilebytes.mymapview;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
import com.google.android.maps.MyLocationOverlay;
import android.os.Bundle;
public class MyMapViewActivity extends MapActivity {
private MapView mapView;
private MapController controller;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initMapView();
initMyLocation();
}
/** Find and initialize the map view. */
private void initMapView() {
mapView = (MapView) findViewById(R.id.mapview);
controller = mapView.getController();
mapView.setSatellite(true);
mapView.setBuiltInZoomControls(true);
}
/** Start tracking the position on the map. */
private void initMyLocation() {
final MyLocationOverlay overlay = new MyLocationOverlay(this,
mapView);
overlay.enableMyLocation();
//overlay.enableCompass(); // does not work in emulator
overlay.runOnFirstFix(new Runnable() {
public void run() {
// Zoom in to current location
controller.setZoom(8);
controller.animateTo(overlay.getMyLocation());
}
});
mapView.getOverlays().add(overlay);
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
AndroidManifest:

/>
</LinearLayout>
map.jar is on the classpath.

Past reports of problems were with widgets and now it has happen to me
with no widgets..
Anybody else see the same problems?
PS Example used was Ed's form his ProgmaticBookshelf Android book..
