how to add token in httpurlconnection class

i am using this code for API access.But i have no idea how to add token as header in httpurlconnection class.my tag for token is "token".I want to add "token" tag with token value in header field but i have no idea.i have googled but i am confused

Upload file using HttpURLConnection

I've copied the following code from here, the one thing that I have replaced is using Map instead of the split as shown in commented lines below, my code start right after it.
This code works perfectly all the time except with one device where it fails sometimes, the code seems to be stuck inside this block, I didn't get any exception btw, it just stuck there.
while (iter.hasNext()) {
....
}
Update
I don't have physical access to the phone so I printed a log for each line, even the exception, and I see that the code is stuck in the loop mentioned above, and also note that the http parameters are fixed to 4.
I put a Log inside it and I see that it reached that block and finished all the params and then didn't get out of it, what am I doing here?

Upload chunks of file Android

I've copied the following code from here, I'm trying to upload chunks of the file to monitor the progress, is it correct to flush the stream as shown in the code below and use it as a progress? the code i'm asking about is surrounded by stars

you can call flush() on DataOutputStream any time, there is no restrictions. It will automatically call flush on underlying connection, so your server should receive that chuck of data immediately, which you can use as progress update.
See here for additional reference
The flush method of DataOutputStream calls the flush method of its underlying output stream.

How to Upload large files using ChunkedStreaming in android?

I need to post some large files to server. I am able to upload the files which are < 3 MB , but while i am uploading a file which is > 3 MB, it shows me the Internal server exception and server response code "500". Initially, I thought it is a server side issue but I can post the large file through iOS app(By using the same url), same way I need to implement it in android.
Here is my code --
public String postMediaDataToServer(String evidenceId, File file) {
String lineEnd = "\r\n";

upload file to server(IIS) by android phone

i googled about my problem but didn't find any thing.
I create a server in win 7 to uploading file from android phone to it.but I can't upload file.
I don't know Is server setting/config is true?![server1][1]
HttpURLConnection connection = null;
DataOutputStream outputStream = null;
DataInputStream inputStream = null;
String pathToOurFile = "/sdcard/test.txt"; //complete path of file from your android device

also I don't meaning of outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile + "\"" + lineEnd);
when I runned above code ,it run til
Log.i("**befwhile*", "twoHyphens ");
please help me!

From the documentation url.openConnection() return URLConnection not HttpURLConnection so the method getResponseCode() not exist. Your downcast to HttpURLConnection will not work. Also all data will be send after flush method.
