Runs in Flash Player or AIR Skinning rulez!!!

9. How to deal with UI?

Flex UI is Native for BlackBerry
BlackBerry 10 and Palybook OS have AIR runtime built-in

10. How to deal with UI?
Is Flex UI good?
Flex UI is not Native for OS
(remember BlackBerry?)
• Pros
• Same UI for all platforms
• Less training / support cost for big corporates
• Cons
• UI has to be perfectly designed to be adopted

11. Specifics of Flex
Requires AIR runtime
•Pros:
• Same codebase for all platforms
• Number of distribution options
•Cons:
• Performance issues, like with any other non-native solution
•Other:
• AIR runtime may be built in with executable
Thursday, September 19, 13

12. Performance?
• UI is slow
• Collections are common but not fast
• High memory usage (AIR runtime)
Thursday, September 19, 13

13. Slower than Native in most some cases
Math calculations are faster than native code on iPad!
Example:
f1(x) = 5.4321 * x 2 + 9.8765 * x
f2(x) = 5.4321 * cos(x)
• Results for
1,000,000 cycles:
C++ Builder XE4 C++ (XCode) Java (Eclipse) Flex
Web
Windows/Chrome
5156 ms 6819 ms
iPad2 24950 ms 26062 ms
iPad4 21306 ms 14064 ms
Nexus 7 14395 ms 18345 ms

14. Performance?
Surflex
var sql:Surflex = new Surflex();
sql.CreateTable("Product", "ProductId", Product.generateTestData());
sql.CreateIndex("Product", "CategoryId");
sql.CreateTable("Category", "CategoryId", Category.generateTestData());
sql.CreateTable("Order", "OrderId", Order.generateTestData());
sql.CreateTable("OrderItem", "OrderItemId", OrderItem.generateTestData());
sql.CreateIndex("OrderItem", "ProductId");
sql.CreateIndex("OrderItem", "OrderId");
sql.Insert("Order", new Order(4, "NO 000459", null));
var orderItem:OrderItem = new OrderItem(15, 4, 8, 8, 400);
sql.Insert("OrderItem", orderItem);
orderItem.Price -= 100;
sql.Update("OrderItem", orderItem);
sql.Delete("Order", function(order:Order):Boolean{return order.OrderId == 4;});
sql.CreateTable("Category2", "CategoryId", Category.generateTestData());
var result:Array;
result = sql.Select("SELECT Category.Name AS Category, Product.Name AS Product,
OrderItem.Quantity AS Quantity"
+ ", OrderItem.Price AS Price, Category2.* AS Mistake"
+ " FROM Category"
+ " INNER JOIN Product ON Category.CategoryId = Product.CategoryId"
+ " INNER JOIN OrderItem ON Product.ProductId = OrderItem.ProductId"
+ " INNER JOIN Order ON OrderItem.OrderId = Order.OrderId"
+ " LEFT JOIN Category2 ON Product.ProductId = Category2.CategoryId"
+ " WHERE Product, Order"
+ " ORDER BY Category ASC, Product DESC", new <Function>[
function(product:Product):Boolean{return product.Status;},
function(order:Order):Boolean{return order.OrderId == 2;}
]);
Data: 7 collections of 1-100K items each.
Goal: find items based on some criteria.
Standard for loops: 4000 ms
Surflex query: 650 ms

15. Performance?
Collections
• Use proper Collections
Thursday, September 19, 13

16. Performance?
Other ways to improve
• Control memory usage with Profiler
• Use proper Collections: Array & Vector vs ArrayCollection
• Use optimized search algorithms (e.g. binary search) to find item
instead of “brute force” for each
• Surflex does its job
• Match class definitions when loading from server
• Read performance tuning tips / best practices
Thursday, September 19, 13

17. How to get data?
Backend?
• ADEP (Adobe Digital Enterprise Platform) /
LiveCycle ES4
• Data access with no line of Java code
• Expensive
• BlazeDS
• Java backend
• Free (reduced ADEP)
• Web services
• XML/AMF (FluorineFx)
