Java StreamCorruptedException格式错误
我一直在试图解决这个问题，我阅读了stackoverflow（和其他网站）上的其他帖子，但找不到答案 基本上，我正在开发一个通过套接字发送apk文件的应用程序。在开始发送文件之前，我还发送了一个包含应用程序名称和相应apk文件大小的字符串 当我创建套接字（就在Begging的右边）时，我还发送两条消息，一条从客户端发送到服务器，说它的昵称，另一条从服务器发送到客户端，只是说你好。这些信息发送得很好 问题是当我尝试读取appName和文件大小时 编辑：刚刚注意到错误格式异常后显示的字符不是来自错误。它的变化取决于我尝试发送的应用程序 这是我的密码 这是内部类clientHandler（Runnable）的run方法，在这里我在客户端创建流对象Java StreamCorruptedException格式错误,java,android,multithreading,sockets,io,Java,Android,Multithreading,Sockets,Io,我一直在试图解决这个问题，我阅读了stackoverflow（和其他网站）上的其他帖子，但找不到答案 基本上，我正在开发一个通过套接字发送apk文件的应用程序。在开始发送文件之前，我还发送了一个包含应用程序名称和相应apk文件大小的字符串 当我创建套接字（就在Begging的右边）时，我还发送两条消息，一条从客户端发送到服务器，说它的昵称，另一条从服务器发送到客户端，只是说你好。这些信息发送得很好 问题是当我尝试读取appName和文件大小时 编辑：刚刚注意到错误格式异常后显示的字符不是来自错误

请注意，之前，在处理连接的线程上（clientHandler和ConnectionHandler）我正在成功发送和交易我想要的数据。问题只出现在下面的线程上。堆栈跟踪没有错误。这是你的期望。你肯定需要发布丢失的客户端代码。已经从客户端添加了代码。我真的需要帮助，我一直在搜索并尝试解决它好几天了。我发现了一些有趣的问题，不知道这是否是问题所在……也许任何读过这篇文章的人都可能知道……我注意到在连接处理程序线程或clientHandler线程（其中inputStreams和outputstreams是本地的）中“交易”的消息工作很好，但是我尝试的第一个，我必须使用一个我必须通过get方法获得的流（因为它在另一端），不工作。这可能是问题的原因吗？如果是，我如何解决它？
