我需要将我的android模拟器目录（'data \ data \ org.mypackage \ file.dat'）中的文件上传到远程服务器，但是当我尝试访问该文件时，它会出现错误，如'error：权限被拒绝'，我将我的sqlite数据库存储在'data \ data \ org.mypackage \ databases \'文件夹中，在应用程序启动期间如果该文件夹中没有sqlite数据库我将其从我的资产文件夹复制到该目录并访问它从那里它的工作完美，但在案件上传任务，它要求许可为什么会发生这种情况？以下是我的uploadFile方法
private void uploadFile(){
HttpURLConnection conn = null;
DataOutputStream dos = null;
