Это mycode, что я получаю "java.lang.RuntimeException: Произошла ошибка при выполнении doInBackground()". Я новичок в андроиде. Я не понимаю, почему эта ошибка возникает, кто-нибудь помогает мне решить эту ошибку.com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Ожидаемое BEGIN_OBJECT но STRING
