org.xmlpull.v1.XmlPullParserException出现错误：未终止的实体引用（java.io.InputStreamReader@a4cc4c8中的位置：TEXT @ 1：683533）

Question

我收到未确定实体参考的错误。仅与奥利奥版本。它可以在其他版本上完美工作。我正在使用kso​​ap2 3.1.1版本。而且这个错误并非每次都出现。有时它运行得很好。我注意到一件事，如果我的json响应太大我得到这个例外。请有人可以帮助我吗？  我在httpTransport.call（SOAP_ACTION，信封）处得到异常; 这是我的代码。

@Override
        protected String doInBackground(Void... params) {
            try {
                Log.d("response","5");

                Log.d("response",SOAP_ACTION);
                SoapObject request = new SoapObject(getString(R.string.WSDL_TARGET_NAMESPACE),OPERTATION_NAME);
                Log.d("response",OPERTATION_NAME);
                Log.d("response",getString(R.string.WSDL_TARGET_NAMESPACE));
