This is a follow-on from my earlier post about building a simple PhoneGap app using Adobe Dreamweaver CS5.5. I built it on Windows targeting Android. I liked the development experience up to the point of trying the app: it looks great, but performance is terrible. That is, you tap a button and there is a perceptible pause before the app responds. It is worse in the emulator than on my HTC Desire, but still poor.

I had thought it was a configuration setting – though Dreamweaver makes it rather hard to access the build settings – but I am now wondering if jQuery mobile plus PhoneGap is just too demanding for most Android devices out there right now. Admittedly my Desire is a year or so old now. See this thread for example:

JQuery Mobile on Android is definitely slow. (Tested A2 and A3Pre on Samsung Galaxy S, HTC Desire, ZTE Blade (edit: 2.2 Froyo) – with PhoneGap, stock browser, Opera Mobile)

Something has to be done. The experience is low quality.

It is worth noting that PhoneGap is not yet a version 1.0 release – I was told it may be done by July. Further, you do not have to use jQuery Mobile with it in Dreamweaver; it just happens to provide a great set of user interface widgets. It may be better on Apple iOS; I have not tried that yet.

Nevertheless, this looks like a significant issue if you planning to dive in and deliver Android apps using the tools in the new Dreamweaver.
