Load your application in a running emulator

ltomuta | 09 November, 2009 17:00

Everybody loves to hate the Symbian SDK emulator. The first reaction to it usually is: "It is slow, really slooooooow, it takes ages to start it" ;)

Yes, it is true, the emulator is slow, but considering the task it has to perform and the complexity of the system it emulates such slowness is to be expected. However, the problem is not as bad as one may think. Yes, the emulator takes time to load, but then why don't you start it in advance and let it load while you browse your recent emails, so that you have it up-and-running at the moment you really need it.

Many developers already with some Symbian experience will tell you that you cannot do that. But yes, you can! The following video will show a basic Qt application being created, built and run into an already running emulator.

Coming up next: Rebuild without restarting the emulator.

Build without an SDK, test without a device

ltomuta | 08 November, 2009 17:50

How many SDKs do I need? Which SDK is best for me?

For a newcomer to the Symbian development world those are among the first questions asked. There are many S60 SDKs on offer, some with feature packs and plugins, some with compiler specific binaries and on top of that many plug-ins. Quite a lot to handle and figure out and nobody likes having all possible SDKs installed.

So what will happen now that Qt is added to the picture? I can design my app using Qt for Windows (or Linux, or Mac) and, according to the "code once, compile anywhere" promise I should be able now to compile this application for Symbian and Maemo devices, with minimal changes. But that means that now I need to install at least one Symbian SDK for building, or a Maemo one, and I should have at least one smartphone for testing. Or do I?

Yes, probably one will have an SDK installed and use its emulator for testing some really complicated solutions, with Symbian components part of the design. And yes, nothing can really replace hand-on-testing. But for simple use cases and for getting started trials one possible solution could be building and testing in the cloud. What you need is an IDE plugin, web hosted SDK and build tools and Forum Nokia's Remote Device Access solution, all mixed together in a rather simple build, deploy and test solution.

Here's a live demo (boring parts speeded-up a bit) of such a solution:

 


 

So, what do you think? Do you like the idea? Would you use it for your projects?

 

The ultimate* software installer debug guide

ltomuta | 29 September, 2009 19:17

There are many things that can go wrong with a SIS installation package and unfortunately the software installer component provides no logging mechanism for developers to be able to precisely pinpoint the point of failure. (More)

Good news on the Horizon

Qt for S60 "Tower" demo running on Nokia N97

Qt for S60 "Tower" released

ltomuta | 25 June, 2009 19:00

You will most probably be glad to hear fresh news from the Qt for S60 port team. They have a new release* out, it is called Tower and it is based on Qt 4.5.2.

There are many new things and many improvements on the existing features, you can see them all listed in the Detailed list of changes for "Tower". To name just a few:

  • "Experimental" support for QtWebkit (must be enabled at configuration time)
  • Phonon support but without the actual playback capabilities.
  • QtSql with sqlite3 backend
  • Improved exceptions safety for Qt Core library (this comes with a patch for the Nokia C/C++ compiler and some really promissing documentation, judging by the title Wink )
  • Input methods

All these and a lot more in an 126 MB binary installer which is smart enough to detect all compatible SDKs in your system and install "Tower" support in all of them. (From what I see the installer needs a bit of optimization or I need a new computer Laughing )

 

 

 

You can find all the binaries, documentation and support information on the Qt for S60 "Tower" pre-release site. Coming soon support for Samsung's S60 devices, an updated version of the Qt for S60 Developer Library here on Forum Nokia and a new release of the Mobility Extensions APIs.

*Please note that this is still a technology preview release and it is not yet ready for production grade application development.

Happy Birthday Symbian Signed!

ltomuta | 18 May, 2009 17:00

The Symbian Foundation is brand new but one of their services is celebrating it's 5th birthday today. You can find on the Symbian.org blog a brief summary of what the service is an some rather interesting usage stats. But more importantly you will find there a glimpse of what they are preparing for the near future:

" ... Lower cost Publisher IDs available to anyone

Lower cost signing and lower barrier to signing

A revamp and rethink of the Symbian Signed Test Criteria
..."

Truly promising plans, I hope that we will hear more details about these soon. Until then: Happy Birthday Symbian Signed!

Symbian Foundation Beta snapshot 

You may have seen in Mark's recent post an invitation to become a Symbian Foundation site beta tester user. Don't worry about missing the deadline and no, you don't have to become a Twitter user just to get an invitation, the invitations are here, one message away for you.

So, are you a software developer curious about the new Symbian Foundation web site? Want to be the first one posting a technical question on that forum? Want to be the first one who answers one? Want to see open sourced code? Let's do it then, let's get you in!

Who can get an invitation?
Any Symbian C++ developer active in the Forum Nokia developer community.

How many invitations are available?
There are enough for everyone. However, the distribution process is manual and time consuming so the most active contributors on the Forum Nokia Discussions Board & Wiki will have priority.

How can I apply?
To get the username and password that will give you access to the web site all you have to do is send me a private message through the Forum Nokia Discussions Board. Easy!

Facelift at SymbianSigned.com

ltomuta | 07 April, 2009 12:00

 

Symbian Signed

 

A refreshed web site welcomes us at http://www.symbiansigned.com, with the site adopting Symbian Foundation's colors. The change is skin deep however so do not expect any [major] changes in the familiar processes.

What is important, although should not be a surprise for anyone by now, is that the ownership of the site is now at Symbian Foundation and that may have impact your access to the site if you haven't accepted the account transfer to the new legal entity.

The site has a message on the main page which explains how one can recover his old account:

 If you missed the chance to consent for your account to be transferred you can follow these steps:

  • Select the option to confirm user account data to be transferred
  • Within 24 hours your account will be propogated (propagated) with the old user data

It is not clear to me what "option" should be selected and an attempt to "transfer" one such lost account has failed We will have to wait a bit more I guess for these things to be fully clarified. Hopefully not many developers are affected by the ownership change, which was after all advertised for months

If you wish to contact Symbian Signed regarding any related issues the location of the support forum remains (for now) the same.

A new video from the TED conference, showing MIT's students enhancing Johnny Lee's work in the search for a practical application.

 

 

Are the presented use cases tempting enough to make you wear one of those devices?
