Question

我有一个用于将文件上传到服务器的Android intentservice。这些文件将每1分钟添加到intentservice队列中。它在操作系统小于5.0.1的android设备中运行正常。但是在上传文件的android 5.0.1中，如果网络丢失，我没有得到任何响应，没有抛出任何异常，意图服务被阻止。文件未从该点上传。我必须重新启动应用程序才能使服务再次运行。下面是我在onHandleIntent方法中的代码。

            int ReadBytes = 0;
            int BUFSIZ = 4096;
            byte Buf[] = new byte[BUFSIZ];
            outputStream = conn.getOutputStream();
            dataOutputStream =  new DataOutputStream(outputStream);
            fileInputStream = new FileInputStream(source);
            long prevBytesRead = 0;
            ReadBytes = fileInputStream.read(Buf, 0, BUFSIZ);
            while(ReadBytes>0){
                dataOutputStream.write(Buf, 0, ReadBytes);
                prevBytesRead += ReadBytes;
                long totalbytes = fileInputStream.getChannel().size();
                ReadBytes = fileInputStream.read(Buf, 0, BUFSIZ);
            }

            outputStream.flush();
            dataOutputStream.flush();

任何帮助都将不胜感激。

您可能正在泄漏流，您应该尝试将其包装在try / catch块中：

try {
      int ReadBytes = 0;
      int BUFSIZ = 4096;
      byte Buf[] = new byte[BUFSIZ];
      outputStream = conn.getOutputStream();
      dataOutputStream =  new DataOutputStream(outputStream);
      fileInputStream = new FileInputStream(source);
      long prevBytesRead = 0;
      ReadBytes = fileInputStream.read(Buf, 0, BUFSIZ);
      while(ReadBytes>0){
          dataOutputStream.write(Buf, 0, ReadBytes);
          prevBytesRead += ReadBytes;
          long totalbytes = fileInputStream.getChannel().size();
          ReadBytes = fileInputStream.read(Buf, 0, BUFSIZ);
      }

      outputStream.flush();
      dataOutputStream.flush();
} catch (IOException e) {

} finally {
      // Close streams with an additional try/catch
}

也许你应该看一下Facebook的推断工具：fbinfer.com，对这些情况非常有用。

当网络丢失时，android 5.0.1文件上传不会抛出异常
