android - java.lang.NoClassDefFoundError: com/androidhive/googleplacesandmaps/PlacesMapActivity

Question

ボタンをクリックしているときに、指定された lan と lat poins に従ってゴーグルマップを表示したいのですが、それをクリックしようとすると、java.lang.NoClassDefFoundError: com/androidhive/googleplacesandmaps/PlacesMapActivity が表示されます。

この問題を解決するにはどうすればよいですか?.

MainActivity.java

 btnShowOnMap.setOnClickListener(new View.OnClickListener() {
 @Override
 public void onClick(View arg0) {
 Intent i = new Intent(getApplicationContext(),PlacesMapActivity.class);
 // Sending user current geo location
 i.putExtra("user_latitude", Double.toString(gps.getLatitude()));
 i.putExtra("user_longitude", Double.toString(gps.getLongitude()));
 // passing near places to map activity
 i.putExtra("near_places", nearPlaces);
 // staring activity
 startActivity(i);
 }
 });

PlacesMapActivity

public class PlacesMapActivity extends MapActivity {
    // Nearest places
    PlacesList nearPlaces;

    // Map view
    MapView mapView;

    // Map overlay items
    List<Overlay> mapOverlays;

    AddItemizedOverlay itemizedOverlay;

    GeoPoint geoPoint;
    // Map controllers
    MapController mc;

    double latitude;
    double longitude;
    OverlayItem overlayitem;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_places);

        // Getting intent data
        Intent i = getIntent();

        // Users current geo location
        String user_latitude = i.getStringExtra("user_latitude");
        String user_longitude = i.getStringExtra("user_longitude");

        // Nearplaces list
        nearPlaces = (PlacesList) i.getSerializableExtra("near_places");

        mapView = (MapView) findViewById(R.id.mapView);
        mapView.setBuiltInZoomControls(true);

        mapOverlays = mapView.getOverlays();

        // Geopoint to place on map
        geoPoint = new GeoPoint(

        // Drawable marker icon
        Drawable drawable_user = this.getResources().getDrawable(
                R.drawable.mark_red);

        itemizedOverlay = new AddItemizedOverlay(drawable_user, this);

        // Map overlay item
        overlayitem = new OverlayItem(geoPoint, "Your Location", "That is you!");

        itemizedOverlay.addOverlay(overlayitem);

        mapOverlays.add(itemizedOverlay);
        itemizedOverlay.populateNow();

        mc = mapView.getController();

                latitude = place.geometry.location.lat; // latitude
                longitude = place.geometry.location.lng; // longitude

                // Geopoint to place on map
                geoPoint = new GeoPoint((int) (latitude * 1E6),

                // Map overlay item
                overlayitem = new OverlayItem(geoPoint, place.name,
                        place.vicinity);

                itemizedOverlay.addOverlay(overlayitem);

                // calculating map boundary area
                minLat = (int) Math.min(geoPoint.getLatitudeE6(), minLat);
                minLong = (int) Math.min(geoPoint.getLongitudeE6(), minLong);
                maxLat = (int) Math.max(geoPoint.getLatitudeE6(), maxLat);
                maxLong = (int) Math.max(geoPoint.getLongitudeE6(), maxLong);
            }
            mapOverlays.add(itemizedOverlay);

            // showing all overlay items
            itemizedOverlay.populateNow();
        }

        // Adjusting the zoom level so that you can see all the markers on map
        mapView.getController().zoomToSpan(Math.abs(minLat - maxLat),
                Math.abs(minLong - maxLong));

        // Showing the center of the map
        mc.animateTo(new GeoPoint((maxLat + minLat) / 2,
                (maxLong + minLong) / 2));
        mapView.postInvalidate();

    }

    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }

私はアンドロイドmanifest.xmlがこのようであるべきだと感じています...

<activity
        android:name=".PlacesMapActivity"
        android:label="Near Places Map View" >

マニフェストを読んで、名前の前にすべてのアクティビティがどのようにポイントを持っているかを確認してください

 <activity
        android:name=".SinglePlaceActivity"
        android:label="Place Details" >
    </activity>

PlacesMapActivity の前にポイントを配置しませんでした

 <activity
        android:name="PlacesMapActivity"
        android:label="Near Places Map View" >

ランチしないので、次のようにします。

 <activity
        android:name=".PlacesMapActivity"
        android:label="Near Places Map View" >
