How to update the old database file with the new database file in android? -


i having application uses sqlite .db in that. having existing database file in application . have have make connection , should download new .db file , have replace existing .db new .db file had downloaded.

i keeping .db file in assests folder of application . people saying readable folder , cant delete file folder .

so please let me know how solve problem .

you can change databasehelper class constructor updating database name,version number important.

 public databasehelper(context context, string dbname, null, int dbversion)

{

    super(context, dbname, null, dbversion);      // todo auto-generated constructor stub  }

instead of using this

public databasehelper(context context) {      super(context, dbname, null, dbversion);      // todo auto-generated constructor stub  }
