Android uploads text files to the server's instance code via HttpPost _android

No more nonsense to say, directly to everyone to paste the key code.

/** * Upload text to the server such as log log * @param urlstr request URL * @param uploadfile log log path */mnt/shell/emulated/0/log/log.log * @par Am NewName Log Name LOG.log * @return * * public static void HttpPost (activity activity,string urlstr,string Uploadfile,str

String end = "\ r \ n";
String Twohyphens = "--"; String boundary = "* * *";//boundary identifier int time_out = 10*1000; 
Timeout time httpurlconnection con = null; 
DataOutputStream ds = null;
InputStream is = null; try {URL url = new URL (urlstr); con = (httpurlconnection) url.openconnection (); Con.setreadtimeout (time_out); con.setconn

ds = new DataOutputStream (Con.getoutputstream ());

}); }

The above content is small to introduce Android through HttpPost upload text files to the server instance code, the code is easy to understand, with comments, if you have any questions please give me a message, small series will promptly reply to everyone. Here also thank you very much for the cloud Habitat Community website support!
