GoogleMap gmap = ((SupportMapFragment) getSupportFragmentManager()

.findFragmentById(R.id.map)).getMap();

gmap.setOnMapLongClickListener(new OnMapLongClickListener() {

@Override

public void onMapLongClick(LatLng latLng) {

MarkerOptions markerOptions = new MarkerOptions();

markerOptions.icon(BitmapDescriptorFactory.fromResource(R.drawable.marker_3g));

markerOptions.position(latLng); //마커위치설정

gmap.animateCamera(CameraUpdateFactory.newLatLng(latLng));   // 마커생성위치로 이동

gmap.addMarker(markerOptions); //마커 생성

}

});

onCreat에 넣어주심됩니다.

요즘한창 v2공부하고있으니 궁금하신점 질문주시면 성심껏 알려드립니다

WifiChecker.zip

WifiManager , WifiInfo 를 이용해 와이파이 상태를 체크하고

신호세기가 10Mbps 이하로 내려가면 자동으로 와이파이를 비활성화 시키는 예제입니다.

주석은 따로 없습니다. 궁금하신점은 댓글남겨주세요.

자동으로 다른 와이파이 검색해서 연결을 변경해주면 더 좋으련만

어떤 클래스나 메소드를 사용해서 할 수 있는지를 몰라 구현은 못했습니다.

아시는분은 댓글좀 남겨주세요 ㅎㅎ

구현하는법 알아냈습니다. 궁금하시면 댓글로 메일남겨주세요 

적용 예시 : http://biig.tistory.com/15

소스반영은 안했습니다. (2013.10.23 수정)
