Error returned after run: (contains a link to the server receive page)
The operation was aborted after the error, and no information was received from the server.
java.io.filenotfoundexception:http://.../upload.php
At Com.android.okhttp.internal.http.HttpURLConnectionImpl.getInputStream (httpurlconnectionimpl.java:206)
The line where studio indicates the error is:
InputStream is = Httpurlconnection.getinputstream ();

Originally thought to be a local file does not exist, the results are confirmed by the file manager, including the code in the check after the "file exists" can be determined that the client file path is correct. Later thought the URL link has a problem, with the computer browser can open normally, can print content, so the server link should also be correct.

Baffled, search for a long time did not find a solution, special to help. Ask the old driver to take the belt.
