Greetings to all, there may be a stupid question.

I open the input form through:

View.VISIBLE

Next, I enter the text in EditText - I check the fields for emptiness through isEmpty. Next, the data is sent to the server, go fine - provided that there was no transfer of text, if you click on the transfer of text, then fatal error falls out.

Can anyone come across this?

  • Maybe because of the difference in \r\n and \n the parser is broken? Is the server side covered with tests? - Costantino Rupert

 java.lang.IllegalArgumentException: Illegal character in query at index

So? It is necessary to screen DATA. See Allowed characters in URL parts.

 HttpGet httpGet = new HttpGet(API_URL + "?"+ URLEncoder.encode(DATA,"UTF-8"));
