3/24/2024 0 Comments Sqlite upgrade database androidI'm guessing the latter because the current version of the application works for me and the feature not working for you is very fundamental and has probably worked from the application's inception. Just increment the DATABASEVERSION constant then implement the onUpgrade method to correspond to these changes (e.g., creating the table that was newly added in version 2). Whether that is because your "DB Browser for SQLite" is failing or because you are misusing that application is impossible to see in that little video. In this case, it is not being properly instructed. To repeat and underscore Simon's observation: The SQLite library, as released, has never had such a fundamental failure as "Database does not update" when properly instructed. My initial reaction to invitations such as "Dig through this load of mostly extraneous information to see what I'm doing" is to decline under this hypothesis: If somebody cannot take the trouble to abstract and report what they see as the relevant aspects of their problem, then I see their problem as worth very little trouble on my part. I was very tempted, as usual under similar circumstances, to just ignore your post. These are the solutions that we went through: Solution 1: Delete the tables that have changed and recreate them Sure, when we started development this was obviously the easiest approach. I’ve been there and battled the fires in production. This makes me think there is something going wrong for you which is not evident in your video. Upgrading databases in Android is difficult. I check if the old one exists and if it does, I delete it. We have performed different SQL queries for reading and writing our data to SQLite database. When the app is upgraded this time, it just writes the new database - it has a new name - instead of the old one. How to Update Data to SQLite Database in Android Read Practice We have seen How to Create and Add Data to SQLite Database in Android as well as How to Read Data from SQLite Database in Android. I know its not the best solution, but it works. This was after creating the DB in a directory for which I had write permission. I ended up adding another database to the assets folder. When I install the same application on my Xubuntu system, then modify some fields using the same sequence as shown in your video, I can close the DB, reopen it, and observe that the modified values are still there. I concur with Simon's comments on this, and have a few more.
