Android Question Save data to text file , when switch the phone off.

[Ross Woodward]

Hi ,

I have been looking through the forums and I could not find what I was looking for.

I have got little app, and when I have some data inserted in I would like to remember them when I turn the phone off, or if the battery dies.
It remembers when I press the middle button to menu. (Pause, Close the App,) It all remembers via the " StateManager" but not when I turn the phone off.

Anyone has any suggestions?

Thanks

I recommend you to use KeyValueStore class. It is based on SQL and therefore is persisted to disk immediately.

Hi Erel,

I should have probably mention. With my state manager, i save to file in xml.
With the KevValueStore, can i use the same file to save the data?

Thanks

No. It will save it to a SQLite db file.

If you want to keep the current file then you can change your code to save the file whenever it changes.

Hi,

My main concern is as it's list of items , which can be long list.
Its saved with state manager to " info file"

and im not entire sure, how would I save it when i turn the phone off/battery dies.
