403 response error whilst trying to make a connection from Android

Question

When I try to make a HTTP POST over Android it's showing the following exception:

java.io.FileNotFoundException

However the same thing is working fine whilst browsing from a browser on the desktop.

It is showing the exception when executing this line:

InputStream inputStream = httpURLConnection.getInputStream();

This is my logcat:

I have tried with the below code:

Where is the server? Is it on your local desktop? HTTP Code 403 is Forbidden. — Ricardo França, Mar 19 '16 at 12:04
no it is public server: http://systechdigital.com action url: http://systechdigital.com/projects/friendLocation/login/checkLogin — im07, Mar 19 '16 at 12:08
I made a post from my desktop using Fiddler and returns 200 too. Did you give permission to accesss internet on de android device? — Ricardo França, Mar 19 '16 at 12:14
yes, I did, below is my permission list I have used in my app: — im07, Mar 19 '16 at 12:20
Can you explain why did you add this "httpURLConnection.addRequestProperty("User-Agent", "RealTimeApps/1.0");" — Arun Shankar, Mar 19 '16 at 12:50
that's not required AFAIK. you can remove that line and it works fine :-) — Arun Shankar, Mar 19 '16 at 12:55
sry for late. yea i know it works. but the error is not because of that cause i have tried removing it too. — im07, Mar 20 '16 at 03:31

You didn't Connect your url connection.

add

httpURLConnection.connect()

just before the

int getPostStatus = httpURLConnection.getResponseCode();

and do the rest only if url connection response is ok like

if (httpURLConnection.getResponseCode() == HttpURLConnection.HTTP_OK) {
  //do your stuff
}

you can check my answer here also : https://stackoverflow.com/a/36099358/2319627

UPDATE

Your code seems ok if you added the httpURLConnection.connect(). I tried your URL, but found the file is not available. Please give a specific file address (like systechdigital.com/projects/friendLocation/login/checkLogin/index.php) as the url and try.

I checked your server. It's not available in php also. So try giving a specific php file address as url. have you given an index.php file in the folder checkLogin? – Arun Shankar Mar 20 '16 at 09:21
Dear #DevTest this a MVC app, that's why the (.php) is not available. "login" is the controller and checkLogin is the method of that controller. – im07 Mar 20 '16 at 10:04

After several attempt the problem is solved. I was getting that 403 response for the mentioned line below: httpURLConnection.setChunkedStreamingMode(0); i was setting the chunked length 0 forcefully that was the problem. thank you all, for your kind co-operation. For more information follow the link : http://developer.android.com/reference/java/net/HttpURLConnection.html#setChunkedStreamingMode(int)
