The stack trace is full of ClassCastExceptions getting thrown by line 49 of your BasicWebServiceActivity.java file. The trace indicates the offending line is in the getListFromXML() method. I copied your code into a text editor and for me line 49 was:

   NodeList nodeListText=( (Document) elementMain).getElementsByTagName("text");

Here you are casting elements as documents which is probably causing the problem
