How to ensure persistence storage of data?

**pgoyal** · 2008-12-03, 11:19

Hello,

How do I ensure that the data created by my application is stored permanently on the phone, and is not erased once I close down the application on my phone?

TIA
Regards

saving it in a file through the PIM API maybe ?
maybe even on an available memory card in the phone ?

Hi Goyal,

The best way to do it is to store the file in the Record Store. There are certain disadvantages of storing the file on the phone's memory or the memory card.

1. The user can delete the file.
2. While writing / reading the file, the phone will ask permissions to read/write user data.
3. Some phones do not allow the MIDlet to access the PIM unless it is signed.

So its always a good option to use the RMS in case of persistence.

Hope this helps.
BR,
