freeResources

@Deprecated
void freeResources()

Deprecated.

This method is used to close the database (or) release any resources after every query. (called after #rawQuery returned cursor is processed) It's not a good practice to get new instance of writable database on every query and close it after the query But if followed some pattern which don't allow to keep many open connections. This can be used to close the connection and free the resources Called Multiple Times So annotated as deprecated (Don't use it until unless forced to)
