Can anybody please suggest if it is possible to draw graphs using rhomobile ? Theoretically since it uses java script i was wondering if i use the raphael.js to plot graphs would it work on all devices. I have to build a mobile app which will plot charts. This app should work on iphone, android phones, RIM and symbian mobiles.
Thanks
RhoMobile uses a WebView, which has the same capabilities as the devices browser, so yes, you could use any JavaScript charting library. However, you will be limited to the devices capabilities (e.g. you will run into issues with older BlackBerry models)

Or using IAMCameraControl in your code.
P.S. Not all cameras support this interface fully, all DirectShow software support is using IAMCameraControl interface (usually) or specific vendor interfaces (sometimes).
Need some help on xamarin Platform. I understand it can be used to develop Android-base and iOS-base App on Xamarin. I have the following questions:
For Android and iOS-based app develop on Xamarin, can the app run on Android-tablet ad iOS-tablet respectively? what I need to do for both tablets respectively?
If there are new controls for android and iOS, how Xamarin will update this for development?
1) Yes they can run on Android Tablet and iPad. Your code logic would remain the same but you would need to provide for the UI since the resolutions are different.
For iOS, Xamarin makes it simple by providing for a Universal template which allows you to provide different layouts for iPhone & iPad.
For Android, there is no template as such but the process remains the same just as you would for phones with different resolutions.
2) Assuming you are talking about the default controls, they will made available in the Xamarin framework via their regular update channels. First they are in Alpha, then in Beta and once the bugs have been ironed out, they are made available to Stable channel which can then be used in the production apps safely.
I would recommend you go through their docs which are quite good and explains this whole thing in quite detail. Xamarin Docs
i am new to monotouch and iOS development environment.
I read Quartz 2D programming guide but I still don't know if it is possible to draw 2 layers on the screen, first layer will be always on the top showing a star or some shape and rest transparent, and the 2nd layer will draw circles where people touch the screen.
I want the first layer to be on the top always and since it is not changing, it should not be re-drawn.
Where can i find example of this or doc?
Thanks
Maybe you should look at the Xamarin Seminar Getting Started with CoreGraphics also a couple of books which have a really nice section of CoreGraphics
Developing C# Apps for iPhone and iPad using MonoTouch iOS Apps
Development for .NET Developers
Learning MonoTouch: A Hands-On Guide to Building iOS Applications with C# and .NET
And a lot of Objective-c examples that you can find on the web, they are quite easy to implement on c# because the exposed API is quite similar.
Hope this helps to get you started.

I have made some applications on J2ME using LWUIT, CLDC 1.1, MIDP 2.0 and they are working great on Nokia handsets.
But when I tried to install these applications on Huawei G7206 (JBlend) some of the applications gives error (NOT SUPPORTED) and some crashes without displaying anything.
I have tested an application without LWUIT and it worked.
My question is,
what is the issue?
Either JBlend does not support LWUIT? or I have to downgrade my applications (I mean to remove some features)?
Does anyone know the limitations to work with JBlend?
Have you tested your applications on other devices?
Confirm that your jad doesn't include any other hidden requirements, jblend generally works with LWUIT but some VM's don't handle the full LWUIT properly and require an obfuscated application or similar hacks.
Whenever we use LWUIT in application the size of the application increase because of the jar file which we add in it. By obfuscation we can reduce the size of .jar file. And can become able to run in device.
Please try of obfuscate the application. You might get the solution of your problem
Anyone have the idea of which Javascript framework is much supported by the cross platform
for PhoneGap App development.
I search on the web and find the JQuery Mobile framework but it is not much compatible with the android it shows problem with UI while it is much supported by the iPhone.
There is any JSframwork supported by the all max platform?
Please Help..
I personally use DataZombie's fork of jQTouch - https://github.com/DataZombies/jQTouch
The transitions and scrolling all work fine on Android unlike some of the others.
Android doesn't have a built-in theme for Android the way it does for iOS, but I was able to put one together for my app fairly easily (it's just CSS and a few images). When it is more complete I will probably release it, but you should be able to do your own or use the jet one (that looks fairly Android-ish).
None of the frameworks really looks like a proper native Android app out of the box as far as I have been able to tell. Nearly all of them seem to have a very iOS-centric navigation system (back buttons in nab bars, etc) that just don't exist in native Android apps. One of the first things I did in my theme was to get rid of any back buttons thus relying on the hardware back button for backward navigation (more like what Android users expect).
