android - Voice catalog is not available in local storage for Here Maps Voice Instruction feature -

following steps in here android sdk developer's guide navigation voice instruction, cannot start voice feature. debug information below:

1. // retrieve voicecatalog , download latest updates voicecatalog voicecatalog = voicecatalog.getinstance(); voicecatalog.downloadcatalog(new voicecatalog.ondownloaddonelistener() { @override public void ondownloaddone(voicecatalog.error error) { if (error == voicecatalog.error.none) { // catalog download successful toast.maketext(getapplicationcontext(), "voice catalog download successful.", toast.length_long).show(); } else { toast.maketext(getapplicationcontext(), "voice catalog download error.", toast.length_long).show(); } } });

ondownloaddone() function receive error: voicecatalog.error unknow

2. voicecatalog.getinstance().islocalcatalogavailable()

islocalcatalogavailable() false.

3. a set of sample voice skins sdk.zip/misc copied /data/app_namespace/files/voices-download

     private void setupvoice() {         // retrieve voicecatalog , download latest updates         voicecatalog voicecatalog = voicecatalog.getinstance();          if (!voicecatalog.islocalcatalogavailable()) {             if (debug) log.d(tag, "voice catalog not available in local storage.");             //toast.maketext(mactivity.getapplicationcontext(), "voice catalog not available in local storage.", toast.length_long).show();              voicecatalog.downloadcatalog(new voicecatalog.ondownloaddonelistener() {                 @override                 public void ondownloaddone(voicecatalog.error error) {                     if (error == voicecatalog.error.none) {                         // catalog download successful                         if (debug) log.d(tag, "download voice catalog successfully.");                          //toast.maketext(mactivity.getapplicationcontext(), "voice catalog download successful.", toast.length_long).show();                     } else {                         if (debug) log.d(tag, "download voice catalog failed.");                          //toast.maketext(mactivity.getapplicationcontext(), "voice catalog download error.", toast.length_long).show();                     }                      // list of voice packages voice catalog list                     list<voicepackage> voicepackages =                             voicecatalog.getinstance().getcataloglist();                     if (voicepackages.size() == 0) {                         if (debug) log.d(tag, "voice catalog size 0.");                          //toast.maketext(mactivity.getapplicationcontext(), "voice catalog size 0.", toast.length_long).show();                     }                      long id = -1;                     // select                     (voicepackage voicepackage : voicepackages) {                         if (voicepackage.getmarccode().comparetoignorecase("eng") == 0) {                             //if (voicepackage.istts()) // todo: need figure out why return false                             {                                 id = voicepackage.getid();                                 break;                             }                         }                     }                      if (!voicecatalog.getinstance().islocalvoiceskin(id)) {                         final long finalid = id;                         voicecatalog.getinstance().downloadvoice(id, new voicecatalog.ondownloaddonelistener() {                             @override                             public void ondownloaddone(voicecatalog.error error) {                                 if (error == voicecatalog.error.none) {                                     //voice skin download successful                                     if (debug) log.d(tag, "download voice skin successfully.");                                      //toast.maketext(mactivity.getapplicationcontext(), "voice skin download successful.", toast.length_long).show();                                      // set voice skin use navigation manager                                     if (voicecatalog.getinstance().getlocalvoiceskin(finalid) != null) {                                         m_navigationmanager.setvoiceskin(voicecatalog.getinstance().getlocalvoiceskin(finalid));                                     } else {                                         if (debug) log.d(tag, "get local voice skin error.");                                          //toast.maketext(mactivity.getapplicationcontext(), "navi manager set voice skin error.", toast.length_long).show();                                     }                                  } else {                                     if (debug) log.d(tag, "download voice skin failed.");                                     //toast.maketext(mactivity.getapplicationcontext(), "voice skin download error.", toast.length_long).show();                                 }                              }                         });                     } else {                         // set voice skin use navigation manager                         if (voicecatalog.getinstance().getlocalvoiceskin(id) != null) {                             m_navigationmanager.setvoiceskin(voicecatalog.getinstance().getlocalvoiceskin(id));                         } else {                             if (debug) log.d(tag, "get local voice skin error.");                             //toast.maketext(mactivity.getapplicationcontext(), "navi manager set voice skin error.", toast.length_long).show();                         }                     }                 }             });         }      }
