Answer 1

lib 파일에 jar파일 있나 확인해보세요

아마 그냥 이클립스 빌드패스에 안드로이드 sdk경로쪽에있는 jar파일만 add시켜서 컴파일할때 에러나는거 같네요

정상적으로 들어가있습니다 ㅠㅠ

Answer 2

com.google.android.gms.maps.MapFragment는 android.support.v4.app.Fragment로부터 상속받아 만들어진 놈이 아닙니다.

SupportMapFragment 를 사용하세요.

package com.androidhuman.example.mapsv2support;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;

public class MainActivity extends FragmentActivity {
   
    GoogleMap mGoogleMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
       
        mGoogleMap = ((SupportMapFragment)getSupportFragmentManager()
                        .findFragmentById(R.id.map)).getMap();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}
