I have been playing around with Kindo for the past few days and I had a few questions that I hope can be answered.

1) how are page transitions timed? I notice that each press it can take a few seconds before the page comes up and am wondering if there are any ways to speed this up?

2) Does kindo use the fastClick plugin to shorten the 2 to 300 ms click delay on mobile devices?

3) I have seen this asked with no reply but can we speed up the page transition?

4) look and feel, I understand you want to try and be native looking but how can I use my own look and feel, do I have to set the device to be like IOS or Android and then change the styles or is there a better way, the documentation does not really touch this or at least the docs I saw did not.



I currently have my app developed in JQM and generally like the framework but I need better performance and I am hoping kindo can provide this. My app loads all the data (JSON) on init and stored them in localstorage, then when accessing a page it loops and displays out the list (maybe 100 rows if that) That being said I still see somewhat laggy performance on android, click wait then page slides in I would like to click or better yet tap and have the page slide in right away.

Thanks!

Hi Mike,

I'll go over your questions one by one:

1 and 2: We are using touch events to fire the interactions, but in Android 4.0 the time between running a transition and it actually starting is considerable and is dependent on the native browser hardware acceleration. Check this documentation article on how you can improve it in PhoneGap.

3: Currently page transitions duration can't be changed easily without changing/overriding the source, can you add this feature request to our Kendo Feedback page on UserVoice and we will consider it?

4. You can force a specific platform style for all platforms and use the Kendo Mobile ThemeBuilder to style it if you want it to look the same everywhere. For the latter to function as advertized, you will need the CSS styles from the service pack, which you can find attached to this post (actually I'm attaching a little newer ones, to avoid an issue that was found in the SP).

Kind regards,
