hi every one!
I am new in J2me , would you mind to tell me how to deal with RecordStore ?
Now I open a RecordStore in startApp() method ,remain the reference to the RecordStore until close the RecoreStore in the destroyApp(boolean) method .But i find when I shut down the phone ,It will not invoke destroyApp(boolean) method ,so the RecoreStore is not closed .
Will it be a big damage to Recoredstore ?

is it a better solution that opening the Recordstore as soon as I want to modify the record in it ,and close it immediately after the operation is done?

Thanks in advance!

Hello Henry,
I'm always accessing RecordStore in as atomic fashion as possible, which means that I
- open RecordStore
- access/save record data
- close RecordStore
in one try-catch-finally paragraph. I have one RecordStore instance variable which I reassign every time I need to access records.
An example:
public class someclass
RecordStore rs;
try {
rs = RecordStore.openRecordStore("myrecords", false);
//do something with the data
}
catch (RecordStoreException rse) {
//do something if there was a problem, or nothing
}
finally {
// Close record store
try { if (rs != null) rs.closeRecordStore(); }
catch (RecordStoreException rse) { }
}
