メソッドgetMap（）を解決できません。 問題がどこにあるのかわかりません。コードの助けが必要です。Androidスタジオを使用してマーカーを取得する必要があります。 JSONでMySQLの場所。Android、メソッドgetMap（）を解決できません
googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.googleMap)).getMap();`
そして、ここでは完全なコードが
public class MainActivity extends FragmentActivity {
private GoogleMap googleMap;
private Double Latitude = 0.00;
private Double Longitude = 0.00;
private GoogleApiClient client2;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
ArrayList<HashMap<String, String>> location = null;
String url = "http://www.evil.cl/getLatLon.php";
try {
JSONArray data = new JSONArray(getHttpGet(url));
location = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map;
for (int i = 0; i < data.length(); i++) {

map.put("LocationID", c.getString("LocationID"));
map.put("Latitude", c.getString("Latitude"));

map.put("LocationName", c.getString("LocationName"));
location.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}

googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(coordinate, 17));
for (int i = 0; i < location.size(); i++) {
