错误：类SupportMapFragment中的getMapAsync方法无法应用于给定类型；

Question

我收到此错误

  

错误：类SupportMapFragment中的方法getMapAsync不能为   适用于给定的类型；必需：找到OnMapReadyCallback：否   参数原因：实际和正式参数列表的长度不同

     

错误：无法访问zzbgl类文件   找不到com.google.android.gms.internal.zzbgl

     

在MapDirectionDisplayActivity.java文件中

这是我的代码

private void getLastActivityInfo() 
{
    lastActivityData = getIntent().getExtras();
}

private void setUpMapIfNeeded() {
    if (mapView == null) 
    {
        mapView = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
        if (mapView != null) 
        {
            CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(lastActivityData.getDouble("point_one_lat")
                    , lastActivityData.getDouble("point_one_lon")), 15);
            mapView.animateCamera(cameraUpdate);
        }
    }

    new DirectionLoadingThread().execute();
