Cursoradapter not updating base tables
The code in Simple Cursor Table Adapter/Vegetable contains the code and SQL to create a table and populate it with some data. The column list that is returned from the cursor defines the data columns that are available for display in the cursor adapter.
The code that creates the database in the Simple Cursor Table Adapter/Home vdb = new Vegetable Database(this); cursor = vdb. Raw Query("SELECT * FROM vegetables", null); // cursor query Start Managing Cursor(cursor); // use either Simple Cursor Adapter or Cursor Adapter subclass here!

This means that every update, insert and delete operation is ACID. This way the other process can access the data in between. A Cursor represents the result of a query and basically points to one row of the query result. With this call, Android checks if someone else queries the data and if finish automatically the transaction and opens a new one.This way we are prepared in case our database schema grows.If you do not have an icon available you can copy the icon created by the Android wizard (ic_in the res/drawable* folders) or rename the reference in the layout file.Unfortunately this requires some overhead in the database processing therefore you should wrap updates in the SQLite database in an transaction and commit this transaction after several operations. This way Android can buffer the query results efficiently; as it does not have to load all data into memory. This way the other process can access the data in between.points to a resources which can be accessed via a provider.
