Then your problem isn't really just the toast message. Check what's at line 103 then check [this](https://stackoverflow.com/questions/14425826/variable-is-accessed-within-inner-class-needs-to-be-declared-final). — Gino Mempin, Jul 29 '17 at 05:35

Use Toast.makeText(context, "토스트메시지입니다.",Toast.LENGTH_SHORT).show();`

@Override
   protected void onPostExecute(String s) {
      super.onPostExecute(s);
      if (s != "FAILED") {


      Log.d(TAG, s);
      Toast.makeText(context, "토스트메시지입니다.", Toast.LENGTH_SHORT).show();

         }
    }

You need to do that on onPostExecute since it is running on the UI thread. And also in Java string comparison is like s.equals("Failed"):

 @Override
                    protected void onPostExecute(String s) {
                        super.onPostExecute(s);
                        if (!s.equals("FAILED")) {


                            Log.d(TAG, s);
                            Toast.makeText(context, "토스트메시지입니다.", Toast.LENGTH_SHORT).show();

                        }
                    }

Error:(103, 68) error: local variable context is accessed from within inner class; needs to be declared final. You just need using "context" instead of "getApplicationContext()".
