    I have completely forgotten how I set this up before on a different IDE and I lost the files from that. How do you setup this code to make it run. I need to put a try{ and a catch but where and how? Thanks for helping.class UpdateText extends AsyncTask<String, Void, String>{@Override protected String doInBackground(String… strings) {BufferedReader br = new BufferedReader(new InputStreamReader(getResources().openRawResource(R.raw.stringtest)));String line = null;while ((line = br.readLine

    java character-encoding inputstream inputstreamreader
    I have a web service receiving a upload text file. So on the server side, I got a InputStream object, and I try to wrap it as an InputStreamReader with “UTF8” as the charset. But I notice when I upload a file encoded in US-ASCII can also work. It seems Java can automatically transform the file from all other charset to UTF8. Am I am right. Can anyone explain me how the charset attribute works. Many thanks !
