Answer 1

oom:out of memory。内存溢出这是个大问题，也不知道你怎么写的？java.lang.NullPointerException: Attempt to invoke virtual method 'void com.handmark.pulltorefresh.library.PullToRefreshScrollView.setOnRefreshListener(com.handmark.pulltorefresh.library.PullToRefreshBase$OnRefreshListener2)' on a null object reference这个你应该知道，空指针异常。你使用了PullToRefresh，setOnRefreshListener（）方法监听器是空的，建议打断点掉试一下
