I have such activityclass code:
package com.pavel.exchanger;
import android.os.Bundle;
import android.app.Activity;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import com.google.android.gms.maps.CameraUpdateFactory;

import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;
import android.support.v4.app.Fragment;
public class SearchExchangerActivity extends FragmentActivity {
static final LatLng HAMBURG = new LatLng(53.558, 9.927);
static final LatLng KIEL = new LatLng(53.551, 9.993);
private GoogleMap map;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_exchanger);
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
.title("Hamburg"));
Marker kiel = map.addMarker(new MarkerOptions()
.position(KIEL)
.title("Kiel")
.snippet("Kiel is cool")
.icon(BitmapDescriptorFactory
.fromResource(R.drawable.ic_launcher)));
// Move the camera instantly to hamburg with a zoom of 15.
map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));
// Zoom in, animating the camera.
map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.search_exchanger, menu);
return true;
}
}

i try to clean project, i added lib and project, i try to google and do some advices.... but nothing helped me(
What i'm doing wrong?
Note: i must run it on android 2.3.3...
How to solve this error?
回答1:
If I had to guess, when you "added lib and project", you added the JAR, not the Android library project. The Play Services SDK is an Android library project that happens to contain a JAR.
The Play Services SDK documentation has the basic steps. Assuming that you are using Eclipse, you need to import the Play Services SDK Android library project into your workspace, then reference that library project from your app (Project > Properties > Android). Also, undo whatever you did originally to attempt to use the Play Services SDK, as that may interfere with the revised setup.
