Question

1) Our Android app will store data in a built-in SQLite DB.

I see the DB can throw android.database.sqlite.SQLiteFullException, but there’s no exact info in API what is the limit.

Could anyone tell what are the size limits for a DB in order not to get into the SQLiteFullException?

I assume DB will store data in device’s internal storage (versus SDCard). Am I right?
Given SQLite DB is just a file, probably the DB size is limited with free internal storage space. Again – Am I right? If yes, then what is the internal storage size on Android? How to detect it? Does it vary on a device model basis or OS version basis?

2) We’ll also need to save app settings. I think SharedPreferences will fit nicely. However the question is – are SharedPreferences saved to the internal storage too? If yes, then is it the same storage where the DB stores its file?

Thanks in advance!

That would be my guess.

On a device model basis.
