| <p>This article covers performance decisions you can make to keep your Flex mobile app running smoothly. The single most important step you can take to ensure solid performance is to use and build off of the many highly-optimized mobile components, skins, and item renderers that ship with Flex 4.6. Using these components and following the set of best practices outlined in this article, you will enjoy high framerates and quick load times on iOS, Android, and QNX devices with a single Flex code base.</p> |

| ActionScript item renderer optimizations</h3> |
| </div> |
| <a name="articlecontentAdobe_text_0" style="visibility:hidden"></a><div class="text parbase section"><div class="Semantic LayoutCellSides LayoutBreakAfter TextMedium TextBreak"> |
| <p>A mobile app may include dozens of item renderers, and when your app does, it is important to optimize them. Optimizing item renderers will keep your application's framerate high during scrolling, which will give your users a smooth, responsive experience. The Flex team recommends you write item renderers in ActionScript to achieve optimal performance. ActionScript item renderers are more difficult to write than MXML item renderers, but the performance gains can be significant. While MXML item renderers provide many conveniences including state syntax, dynamic layout, and binding expressions, ActionScript item renderers strip these out for speed.</p> |
| <h4>Subclass LabelItemRenderer or IconItemRenderer</h4> |
| <p>You can improve performance by writing your item renderer in ActionScript and building off of the highly-optimized Flex LabelItemRenderer or IconItemRenderer. To implement your LabelItemRenderer or IconItemRenderer subclass, you override the item renderer's data setter and the <code>createChildren</code> , <code>measure</code> , <code>drawBackground</code> , and <code>layoutContents</code> methods.</p> |
| <p>To get started with an ActionScript template that extends LabelItemRenderer and overrides those methods, follow these steps:</p> |
| <ol> |
| <li>In Flash Builder 4.6, choose File > New > Item Renderer.</li> |
| <li>Type your item renderer's name.</li> |
| <li>Select the second template titled Custom ActionScript Item Renderer For Mobile List (ActionScript).</li> |
| <li>Click Finish.</li> |
| </ol> |
| <p>The generated code will include comments that explain what to do in each overriden method. To get more specific code examples for each overidden method, don't be afraid to dive into the superclass's methods.</p> |
| <p>If you're familiar with the Flex component lifecycle, you may notice one new convention: <code>updateDisplayList</code> has been divided into two new methods, <code>drawBackground</code> and <code>layoutContents</code> . In LabelItemRenderer and IconItemRenderer, <code>updateDisplayList</code> simply calls <code>drawBackground</code> first and calls <code>layoutContents</code> second.</p> |
| <p>Figure 1 shows an example of a simple ActionScript item renderer that displays stock ticker symbols and their change in value.</p> |

| <h4>When displaying an image in an item renderer, use or subclass IconItemRenderer</h4> |
| <p>Internally, IconItemRenderer uses the Flex ContentCache class to cache externally downloaded icon images. This means that when a user scrolls down a list containing IconItemRenderers, external images will take a moment to load from the server, but when the user scrolls back up, the images will appear immediately, coming directly from the IconItemRenderer cache.</p> |
| <h4>Use StyleableTextField to display text instead of Label or RichText</h4> |
| <p>StyleableTextField is much faster at rendering text than Label or RichText, so always use it to display text in ActionScript item renderers. Note that StyleableTextField is ActionScript only, so you cannot use it in MXML item renderers or MXML views.</p> |

| MXML item renderer optimizations</h3> |
| </div> |
| <a name="articlecontentAdobe_text_3" style="visibility:hidden"></a><div class="text parbase section"><div class="Semantic LayoutCellSides LayoutBreakAfter TextMedium TextBreak"> |
| <p>Writing item renderers in ActionScript will yield optimal performance. However, you can still approach similar performance levels with MXML item renderers, but you will need to carefully tune them with the following optimizations.</p> |
| <h4>Keep your item renderer's appearance static and carefully use cacheAsBitmap</h4> |
| <p>The <code>cacheAsBitmap</code> property can affect performance positively or negatively, depending on how it's used. Only set <code>cacheAsBitmap</code> to <code>true</code> on an item renderer if its internal appearance does not change frequently. When the item renderer's appearance stays the same and only its position changes, the runtime can quickly redraw the item renderer's cached bitmap in its new position. However, every time the item renderer's internal appearance changes, the runtime has to recreate a bitmap, which takes time and can hurt performance.</p> |
| <p>The same goes for all components, not just item renderers. For example, never set <code>cacheAsBitmap</code> on a List. A List component's internal appearance changes every frame during scrolling, which would require the runtime to regenerate expensive bitmaps every frame, slowing the framerate down to a crawl.</p> |
| <p>For more information on <code>cacheAsBitmap</code> , watch Glenn Ruehle's explanation of correct <code>cacheAsBitmap</code> usage in minute 47 of his talk <a href="http://tv.adobe.com/watch/max-2011-develop/best-practices-for-building-flex-tablet-applications/" target="_blank">Best Practices for Building Flex Tablet Applications</a>.</p> |
| <h4>Keep your item renderer rectangular and opaque and set opaqueBackground</h4> |
| <p>Unlike <code>cacheAsBitmap</code> , which can easily hurt performance if misused, <code>opaqueBackground</code> can only improve performance. However, your item renderer must be rectangular and opaque for it to render correctly.</p> |
| <p>Under the hood, the <code>opaqueBackground</code> property instructs the runtime to use a highly optimized rendering path that can ignore transparency calculations.</p> |
| <p>To use the <code>opaqueBackground</code> property, you set it to a specific color on an item renderer. Even though you set a single color for <code>opaqueBackground</code> , you can still completely draw over that color with another custom opaque background and reap the performance benefits.</p> |
| <p>Here's a simple item renderer that sets <code>opaqueBackground</code> for performance gains and completely paints over the solid background color with a gradient-filled Rect:</p> |

| <h4>If you draw your own background, turn off autoDrawBackground</h4> |
| <p>If you define a background Rect in your item renderer as in the previous code example, you should turn off <code>autoDrawBackground</code> . This instructs Flex to not waste time drawing a default background that you will paint over anyway.</p> |
| <h4>Use Label instead of RichText to display text</h4> |
| <p>Although StyleableTextField is the fastest component for displaying text, you cannot use it in MXML. The next fastest component that you can use in MXML is Label. Most importantly, you should always avoid using RichText in your app because it is not optimized for mobile.</p> |
| <h4>Override the data setter instead of using binding expressions</h4> |
| <p>Under the hood, binding expressions dispatch events and run extra ActionScript code. Complex binding expressions and two way binding expressions are even more expensive. Luckily, you can easily avoid using binding expressions in an item renderer by updating its display in an overridden data setter.</p> |
| <p>For example, you can override the item renderer's data setter like this:</p> |

| <p><b>When displaying external images in your item renderer, use a shared ContentCache</b></p> |
| <p>If you are downloading external images into an item renderer, you don't want to re-download them every time the data item scrolls in and out of view. As mentioned before, the ActionScript IconItemRenderer uses a ContentCache to keep your app from re-downloading assets. You can make a similar optimization in your MXML item renderer by declaring a static ContentCache instance and setting any BitmapImage component's <code>contentLoader</code> property to it. Then, all item renderers of that type will share the ContentCache instance, which will automatically load and cache your images. This is easier than it sounds, so check out this code example:</p> |

| <h4>To position components, use BasicLayout or ConstraintLayout instead of nesting Group containers</h4> |
| <p>You should keep the display hierarchy as shallow as possible. Nesting Group containers with combinations of VerticalLayout and HorizontalLayout to create complex layouts will run a lot of unnecessary layout code. Instead, consider using ConstraintLayout or specifying component positions explicitly using BasicLayout constraints such as <code>left</code> , <code>right</code> , <code>top</code> , and <code>bottom</code> . You might have noticed that in the code examples, I've already been specifying positions explicitly instead of using nested Groups or dynamic layouts.</p> |

| View optimizations</h3> |
| </div> |
| <a name="articlecontentAdobe_text_14" style="visibility:hidden"></a><div class="text parbase section"><div class="Semantic LayoutCellSides LayoutBreakAfter TextMedium TextBreak"> |
| <p>Mobile views should be written in MXML. Unlike item renderers, there is usually only one view visible at a time, so the ease of use of MXML outweighs the performance benefits of ActionScript. Regardless, there are important optimizations you need make to ensure your app is quick and responsive when switching between views.</p> |
| <h4>Override the data setter instead of using bindings or initializing a View's appearance in a creationComplete handler</h4> |
| <p>Do not initialize a View's appearance in a <code>creationComplete</code> handler because this can cause the view to be reprocessed, which will delay the view transition. Instead, change your view's appearance in an overridden data setter. As with item renderers, overriding the data setter can eliminate expensive binding expressions.</p> |
| <h4>Start asynchronous operations in viewActivate and cancel them in viewDeactivate</h4> |
| <p>Asynchronous operations such as server calls can return during view transitions and require extra code to run, potentially causing a view transition to stutter. It's best to start an asynchronous operation after the view has already transitioned onto the screen, in a <code>viewActivate</code> handler. You should also consider cleaning up outstanding asynchronous calls in a <code>viewDeactivate</code> handler before switching views.</p> |
| <h4>Initialize child components lazily</h4> |
| <p>Before a view transition begins, Flex needs to create and lay out all of a view's children. You should keep views as lightweight as possible initially to minimize the delay between user interaction and when a view transition starts playing. Whenever possible, create components incrementally after the view has already transitioned onto the screen, which is after the <code>viewActivate</code> event. Definitely avoid creating components that are not visible in the initial state of the view.</p> |
| <h4>Use includeIn or excludeFrom instead of the visible property to hide child components</h4> |
| <p>When possible, use <code>includeIn</code> and <code>excludeFrom</code> to remove components from the display list when they shouldn't be visible. This keeps them from being processed. In contrast, if you set <code>visible</code> to <code>false</code> the components will remain on the display list, requiring unnecessary layout and rendering processing.</p> |
| <h4>To keep views in memory, set destructionPolicy to "never"</h4> |
| <p>If a user switches back to a view frequently, you might want to avoid the cost of creating it again by keeping it in memory. However, remember that memory is a precious resource on mobile devices! Keeping complex views in memory (or even keeping too many simple views) can decrease performance if you are pushing the limits of the device's RAM.</p> |
| <p>To improve processing time at the expense of consuming more memory, set <code>destructionPolicy</code> to <code>"never"</code> on a View like this:</p> |

| <p>The following optimizations help you speed up various types of graphics in your app, whether the graphics are found in item renderers, views, or other components.</p> |
| <h4>Create multiple copies of an image instead of scaling it or using bitmap smoothing</h4> |
| <p>Image scaling with smoothing looks great but requires a lot of processing power. Instead of creating one large image asset and scaling it down for different screen resolutions and DPI levels, create multiple versions of the image asset in different sizes. Check out Flex computer scientist Jason San Jose's article <a href="/devnet/flex/articles/mobile-skinning-part2.html">Flex Mobile Skins – Part 2: Handling Different Pixel Densities</a> for a detailed tutorial with best practices.</p> |
| <h4>Use prebaked assets, text doubling, or RectangularDropShadow instead of filters</h4> |
| <p>Like most high-quality image processing operations, Spark filters are computationally expensive on mobile devices, and you should avoid them in favor of other techniques. Most of the time, you can draw a drop shadow directly into your image assets. When working with text, you can duplicate it and offset it to create a drop shadow effect. If you want a drop shadow on a rectangular component, Flex provides a very efficient replacement for DropShadowFilter called RectangularDropShadow. RectangularDropShadow is not a filter, but a component, which you can use much like a Rect.</p> |
| <p>Use RectangularDropShadow like this:</p> |

| <h4>Use BitmapImage instead of Image for embedded images</h4> |
| <p>The BitmapImage component is a lightweight version of the Image component. Both components can display embedded image assets. The biggest difference between them is that Image can load external images right out of the box, whereas BitmapImage requires some set up to load external images.</p> |
| <p>Unlike BitmapImage, Image is also skinnable and supports a missing image indicator. For embedded images, you don't need all of these extra features, and you should use the lighter-weight BitmapImage component instead.</p> |
| <p>Use the BitmapImage component like this:</p> |
| <div class="PanelFillLight PanelBevelTop LayoutCell LayoutRow"><code class="CodeBlock"><s:BitmapImage source="@Embed('assets/icon.jpg')"/></code></div> |

| <h4>Use PNGs over GIFs and JPEGs</h4> |
| <p>The runtime is simply faster at decoding the PNG file format, so you should use it instead of GIF and JPEG images wherever you have a choice.</p> |
| <h4>Use FXG files for nontrivial vector graphics</h4> |
| <p>For convenience, you should use MXML primitives to draw simple vector graphics like background rectangles. However, for more complex shapes and vector artwork, you should create FXG files in Adobe Illustrator or a similar design tool. FXG files consist of a precompiled sequence of drawing instructions that can execute faster and use less memory than a large set of primitives declared in MXML. Check out the <a href="http://help.adobe.com/en_US/flex/using/WS145DAB0B-A958-423f-8A01-12B679BA0CC7.html" target="_blank">FXG and MXML Graphics reference article</a> for more information about FXG versus MXML graphics.</p> |
| <h4>Reduce the number of effects running concurrently</h4> |
| <p>Flex provides effects such as Resize or Fade, which make it easy to animate the user interface in response to touch interaction. It's best to limit the number of effects running at the same time because they can add up in terms of processing cost.</p> |
| <h4>Use CSS styles instead of reskinning a component whenever possible</h4> |
| <p>By using CSS styles, you leverage the highly-optimized default Flex mobile skins. Most of the time, styling will be sufficient for customizing the look and feel of your UI components. For some examples of CSS styling, see Holly Schinsky's article <a href="http://devgirl.org/2011/05/09/styling-the-flex-4-5-mobile-application-tabs-and-actionbar/" target="_blank">Styling your Flex 4.5 Mobile Application Tabs and ActionBar</a>.</p> |
| <h4>When creating a custom skin, extend the default mobile skins in ActionScript</h4> |
| <p>If CSS styling is insufficient, you may decide to write a custom mobile skin for a component. You should write the skin in ActionScript and extend the default Flex mobile skins to take advantage of their underlying performance optimizations. Check out <a href="/devnet/flex/articles/mobile-skinning-part1.html">Jason San Jose's series of articles on mobile skinning</a> to guide you through the process.</p> |

| <p>At every step in your app's development process, make sure you're hitting your performance benchmarks. Don't let yourself layer on another feature until you're satisfied with your app's performance at its current stage. Saying "I'll fix it later" can be the first warning sign of an overambitious feature or a poor architectural choice. Both are much easier to address sooner rather than later.</p> |
| <p>Many of the optimizations in this checklist come directly from the fantastic talks by former and current Flex SDK team members, including Evtim Georgiev, Steven Shongrunden, Glenn Ruehle, and Ryan Frishberg. I highly encourage everyone interested in more detail about these topics to watch the talks on Adobe TV:</p> |
