Re: Coding a better flex mobile app

Hi Gabriele, i would suggest you to continue using Apache Flex but adding the Starling framework and the fathersUI interface. This software stack will improve your app performance FOR SURE but you have to consider to re-code at least the view layer (if you developed in MVC architecture) or the ent

Hi Om, Tom and Justin, I experienced performance problems with bitmapdata (I had to avoid pixel to pixel iterations cause they're too slow, also on small images of 1024x768px) and in general with views transitions and UI components (they aren't as fluid and responsive as the native apps' ones

Yep, although it's true that retina iPads trend to run a little bit slow in some versions of the SDK.

Hi Javier, RenderMode is set to auto and the ItemRenderer used is the bundle LabelItemRenterer. The higher framerate I can get on a nexus 4 is 30-33 fps, this gain has little impact on the scrolling smoothness perception. Javier Guerrero García wrote > renderMode? cacheAsBitmap=true? use Styl

Use rendermode direct, set cacheasbitmap=true in your renderers, set the opaquebackground to any color, disable autoDrawBackground, and use StyleableTextField as itemrenderer (it's harder, but faster :) On Mon, Apr 7, 2014 at 3:37 PM, After24 wrote: > Hi Javier, > > RenderMode is set to auto an

You have a very single way to communicate, anyway... When you say : "wait until you enable caching and disable backgrounds ;) " are you talking about the cacheAsBitmap property ? if it's the case I'm just saying that this property is set to true in the constructor of the LabeItemRenderer. And wh

Ok, since you said "the list component never reaches 50/60 fps even when its itemRender is well optimized", I though the purpose was to reach the highest possible performance, not to study the different parameters. If so, your code is perfectly ok (expect for the assignment of a boolean to opaqueB
