Android Room database transactions

问题 With the new Room Database in Android, I have a requirement where there are two sequential operations that needs to be made: removeRows(ids); insertRows(ids); If I run this, I see (on examining the db) that there are some rows missing - I assume they are being deleted after inserting. viz. the first operation is running in parallel to the second. If I use a transaction block, such as this, then it's all fine - the first operation seems to complete before doing the second: roomDb

问题 I am getting this error while running program with Room Database Room cannot verify the data integrity. Looks like you've changed schema but forgot to update the version number.

Ship an application with a database

由 拟墨画扇 提交于 2019-11-25 21:36:13
问题 If your application requires a database and it comes with built in data, what is the best way to ship that application? Should I: Precreate the SQLite database and include it in the .apk ? Include the SQL commands with the application and have it create the database and insert the data on first use? The drawbacks I see are: Possible SQLite version mismatches might cause problems and I currently don\'t know where the database should go and how to access it. It may take a really long time to
