What is a maximum size of SQLite database on Android?

Question

I have a SQLite db that size is over 2.6 GiB. (The db contains maps.) This db is used by RMaps app. When move the maps to some parts at maximum zoom, the app suddenly closes. However, there is no force close message, no report button. So, I've got an idea that it is caused by reading blocks that are beyond a certain limit e.g. max(int). Since RMaps is just using simple SQL statements, I think that the problem is not in RMaps but rather in Android SQLite driver.

Is there a size limit of SQLite database on Android?

(I have Froyo on Nexus One, but I do not think that this is just a problem of Froyo.)

UPDATE2: The SQLite db is stored on SD card, there is enough space.

Answer 1

I suspect it is ~2 gigabytes (that might be due to 32-bit architecture, although certain programs come with largefile support, allowing more that that). Fortunately android.database.sqlite.SQLiteDatabase has following API call that returns the maximum size the database may grow to:

long getMaximumSize()

Eventually you might want to look into database sharding ;)
