java.net.SocketTimeoutException:读取超时问题

当我尝试连接到

web服务时，为什么会出现此
异常
。我在stack overflow中搜索相关错误，但实际上无法找出原因？
我假设“com.Webservice.downloadFileAddPassword”是您创建的包，您的web服务是Webservice.java。如果这是真的，那么您在Webservice.java的第192行有一个错误。这并不是说您可能没有访问web服务，而是web服务中的操作时间或进程超时了。您是否对web服务进行了单元测试

我在stacktrace中读到，您有一个正在调用的InputStream，当尝试连接或从源读取时，它超时的时间太长

所以基本上：webservice使用的输入流太长了。我想我知道的还不够多，不能只看一下你的stacktrace就能提供更多的信息

堆栈跟踪作为更可读的格式：

AsyncTasks最好用于短操作（最多几秒钟），而不是使用asyntask
。为什么不使用服务或下载管理器？关于您的异常，让我们看看人们怎么说：）不，SSL握手超时了。查看堆栈跟踪。
