Android Question where can I find documentation for things like tableview and DBUTILS for b4j and b4a?

You may have a look at chapter 3 DBUtils version 2 in the B4X SQLite Database Booklet.
There is no documentation about TableView.
Then it depends which TableView you want to use.
FlexibleTable or B4XTable?
FlexibleTable is an older B4A table view. The zip file in the thread contains a demo project showing how to use it.
You can load directly a SQLite query into it, without DBUtils.
B4XTable is a more recent, cross platform, table view. I haven't looked deeply into it.
