J2me检测到应用程序的首次启动

据我所知，没有比这更简单的方法了，但这还是很容易的。

    public static boolean isFirstRun() {        RecordStore rs = null;        try { rs = RecordStore.openRecordStore("myAwesomeRecordStore", false); //check return false; //record store exists, so it's not our first run        } catch (Exception e) { //RecordStoreNotFoundException, but we need to catch others anway try {     rs = RecordStore.openRecordStore("myAwesomeRecordStore", true); //create } catch (Exception e1) {}        }        finally { if (rs != null) try {rs.closeRecordStore();} catch (Exception e) {}        }        return true; //so, record store did not exist and it was created (if no error occured (there shouldn't be any errors anyway))    }
