蓝牙接收项目后，更新本地相册

蓝牙接收文件，必须携带文件的名字

1.修改文件储存的位置
private static final String FILE_PATH = Environment.getExternalStorageDirectory() + File.separator + Environment.DIRECTORY_DCIM + File.separator + "Camera" + File.separator;
获取文件名字
 FileReceiveStatus fileReceiveStatus = (FileReceiveStatus) obj;
 Log.d("liuyq====", "socketNotify: 文件接收成功"+fileReceiveStatus.getFilename());
2.通知更新媒体资源    
File file = new File(FILE_PATH+"/2019_12_20_10_12_37.jpg");
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + file)));
