android - Upgrading database version of an already built database -


i have database stored in assets folder built using sqlite manager. now, when add new records table of database, have uninstall , reinstall app. have upgrade database in right way without uninstalling app?

note:

  • my oncreate() , onupgrade() empty because mentioned, database built.

  • i call super(context, db_name, null, 1); in helper constructor, changing version not because onupgrade() empty.

to allow upgrading, must implement onupgrade , whatever necessary convert old version new version.

if have new database file in assets folder, must replace old file. not possible sqliteopenhelper because has active transaction while onupgrade called, when not using automatic creation/versioning mechanism, there not reason use sqliteopenhelper in first place.
