it happen because somewhere somehow manually close (call *.close() or that) data source object - no matter is, http or database connection. thus, put object in sort of closed state, , can not requery info data source.
that's quite typical mistake when close datasource, intend use repeatedly further.
to avoid this, call *.close() method on datasource, when not need anymore. example, activity's ondestroy() method.
the answer pretty general, did not provide enough details on code.
