I have an app that creates a database and do some stuff. I am wondering if i upload a new db to a server and download it to the exact folder where the older one exists it will be overwritten and i am good to go? Or there will be a problem. Assuming it has the same name, same column names, etc. Of course i am reffering to sqlite.
In Android, when performing a database update you should be using onUpgrade inside of the SQLiteOpenHelper. One way of doing this is to download text files that include the sql instructions needed to modify the current database or update rows with new data. The reason you have to do this is because Android will only create the database once. After the initial creation the call to onCreate for the database will not occur.
