以下是使用osmdroid和OSMBonusPack库批量清除上一秒多个标记，并刷新最新多个标记位置和弹窗信息的示例代码：

            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_PERMISSIONS_REQUEST_CODE);

                startLocationUpdates();

                Toast.makeText(this, "Location permission denied", Toast.LENGTH_SHORT).show();

    private void startLocationUpdates() {
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            myLocationOverlay.enableMyLocation();
            myLocationOverlay.enableFollowLocation();
        }
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        // Pass the event to the MapView so it can handle zooming and scrolling
        return mapView.onTouchEvent(event);
    }
}

上述代码中，我们首先在布局文件中添加了一个MapView，以显示地图。然后，在Activity中初始化MapView，并添加一些基本的控件和覆盖物。在单击地图时，会创建一个Marker并将其添加到地图上，并为其设置InfoWindow。我们还提供了清除和刷新标记的按钮，分别通过clearMarkers和refreshMarkers方法实现。在checkPermissions方法中，我们检查了定位权限，并在权限被授予时启动定位更新。

请注意，上述代码中的refreshMarkers方法需要根据需求进行定制，以添加新的标记和弹窗信息
