your POST code is fine.

problem not in content size , but in a way you are building json payload.

you have doublequotes in content

so, using string interpolation for json building like this:

You should not read line by line if you want to read first line as header because the Apache CSV tries to read every line as header. So the exception is thrown. Instead you should pass reader to read data. Below code works fine.

You do not want to leave the connection open. That will present the risk of a resource leak. I would recommend creating a custom InputStream implementation that automatically closes the connection when the stream is closed:

As rightly pointed out by @Alexander Petrov , you are declaring a table type with name dbo.filters

That's because you're currently using runBlocking.

You need to launch it in a coroutine scope to make it asynchronous, additionally you can switch the operation to IO.

Add this to you app

The code is sending data to a URL, which is ignored if there is not code to handle it on the server.

If your code is on the website server, you can use the FileWriter class to write to the directory of your website contents.

For example, assuming network_black_list.txt is in /var/www/html:

That is JSON formatted data; JSON is not regular, tehrefore, trying to parse this with a regular expression is impossible, and trying to parse it out with substring and friends will take you a week and will be very error prone.

Read up on what JSON is (no worries; it's very simple to understand!), then get a good JSON library (the standard json.org library absolutely sucks, don't get that one), such as Jackson or GSON, and the code to extract what you need will be robust and easy to write and test.

You should pass the download button as a constructor dependency and wrap it in a weak reference as you've done with context.

I think it may have thrown a ClassCastException because you attempted to force cast it from doInBackground() and the download button from the host of your AsyncTask was a weak reference of the view.

Minor modification to your existing code should work fine:
