Android: Handling error responses

Question

I'm working on an app that makes use of a public api that sends back xml responses.  When everything goes well, air handles the xml and creates as components to turn the results into typed objects.  The problem arises when submitting information to the api that results in an api error.  The xml payload is completely reformatted.  How do I set up flashbuilder (burrito) so that it recognizes when a server error is returned?

Hi,
Using function module 'FORMAT_MESSAGE' you can capture the messages.
Here is a sample of the program code for that:
  LOOP AT it_messtab.
  CALL FUNCTION 'FORMAT_MESSAGE'
    EXPORTING
      id     = it_messtab-msgid
      lang   = it_messtab-msgspra
      no     = it_messtab-msgnr
      v1     = it_messtab-msgv1
      v2     = it_messtab-msgv2
    IMPORTING
    msg    =  g_msg
  EXCEPTIONS
      OTHERS = 0.
  IF it_messtab-msgtyp = 'S'.
    it_sucess-sucess_rec = g_msg.
    it_sucess-lifnr = it_header-lifnr." Based on your field
    it_sucess-tabix = v_lines.
    APPEND it_sucess.
  ELSEIF it_messtab-msgtyp = 'E'.
    it_error-error_rec = g_msg.
    it_error-lifnr = it_header-lifnr.
    it_error-tabix = v_lines.
    APPEND it_error.
  ELSE.
    it_info-info_rec = g_msg.
    it_info-lifnr    = it_header-lifnr.
    it_info-tabix    = v_lines.
    APPEND it_info.
  ENDIF.
ENDLOOP.
Hope this helps.
