Feedback on Nokia Qt SDK 1.1 TP on Mac OS X

A few weeks back I wrote about my experience with Qt 4.7 and Symbian^3 development. Just as made for me, Forum Nokia released some two weeks ago a technical preview of the Nokia Qt SDK 1.1 including Qt 4.7.1, Qt Mobility 1.1, latest Qt Creator and tools for building apps for Symbian and Maemo. The SDK also contains device binaries to run apps on Symbian devices. This basically covers most of the criticism I gave Nokia in my previous post, except that I still cannot publish apps on OVI Store, since this is not an official release of the SDK. Unfortunately I also don't have a Windows machine with me nor a Symbian device to test the SDK with, so I cannot say much about the device development side of this release. But I can give some user feedback on the SDK release as a whole. As this is a technical preview of the official release, please bare with me, as I think it is appropriate to also give feedback on smaller details, nitpicking if you will, of this release.

Installation

You can download the binaries from Forum Nokia's webpage. Nothing special about that. But it seems that Nokia Qt SDK requires me to install Apple's xCode on my machine first. I can understand this, since xCode comes with the GCC toolchain for Mac. But isn't this a bit ironic? Nokia wants Apple to distribute the required tools for them. I cannot imagine Apple having patents or copyright to the open source gcc tools, so I think Nokia could as well distribute these binaries in the SDK. After all, xCode installation is more than 2GB so if I don't intend to develop Mac OS X or iPhone application on my Mac, this seems a bit overkill to me. And not the best developer experience.

The first nitpick of this post comes from the path how the installation image is mounted in Mac OS X. As you can see from the image, Apple's xCode has a nice name to the installation image, while Nokia's SDK is some weird path. Yes, a small detail but as a whole it all counts. The second nitpick comes from the installation process. The installation process itself went smoothly and it was as easy as any application installation on a Mac. But just look what happens when Madde is being installed and you expand to see the empty or messed up installation details. This is already a bit of embarrassing so I hope Nokia will fix this for the official release. After the installation is done you are met with a familiar Qt Creator that is refreshingly recent - built January 14th which would make it a recent build of version 2.1. Also all the latest Qt and Qt Mobility libraries are there and you have three development targets to choose from: desktop, Qt Simulator and Remote Compiler. The Remote compiler target is pretty interesting so a few words about that shortly. I used QuickFlickr (which is a Flickr client built on Qt Quick requiring Qt 4.7) to test out this SDK release and to my no surprise, I manage to compile and run QuickFlickr on the desktop target without any issues. Hurray!

Remote compiling

Remote compiling and Remote device access are things that show that Nokia has a bunch of bright people working for them. I haven't used them before and as concepts that you can actually use they are quite brilliant. Remote compiling is one of the targets predefined on the Nokia Qt SDK 1.1. It is also the only way to build Symbian installation packages on Mac OS X and Linux. So instead of building the package on your host machine, you send the source code over the Internet to some Nokia's machine and it will compile the source for you and you will get as a result a .sis package. And I must tell you that it worked well! You just have to login with Forum Nokia account credentials and it will work our of the box. Compiling QuickFlickr with the remote compiler target took something around 15 seconds and I had myself a .sis package I could install on my device if I had one. But there are a few things I must comment about. First of, this is a technical preview release of the latest release of the Nokia Qt SDK. But for whatever reason, remote compiler is configured to use Qt 4.6.3 as the default target. Why? Didn't I just download a technical preview so I can preview the latest and greatest? It could also state more clearly which Qt version I am now using when compiling remotely. Also the introduction of Remote compiler could have been done better. I was new to this concept so it would have made me feel better if during initial launch I was introduced to the concept and it offered me right away a way to login (or create an account) to Forum Nokia so I can use the remote compiler right away. What about security? The concept worked well, as I saw, but would larger corporation building their product rely on Remote compiler and send their source code over (unsecured) Internet connection to some Nokia hosted server? Maybe not. But for individual 3rd party developers, it might offer a good way to get Symbian packages if you want to use OS X or Linux for development. And why not on Windows too (is it available on Windows too btw?).

Remote device access

I didn't have a Symbian device with me (I am here in Mountain View on an assignment currently) so I had the opportunity to test QuickFlickr on a Symbian device that was running remotely and hosted by Forum Nokia. This is also one of those more genius concepts that Forum Nokia offers the 3rd party developers. Unfortunately as it turned out, it wasn't really ready to replace a native device next to you for R&D purposes.

First of all, Forum Nokia should check the JavaScript for checking if the browser is ready to use their site. I have a hard time believing Chrome 8.0 is not modern enough for Forum Nokia. Basically what you then do is that you reserve time on some device for up to one hour and you can use it remotely from your desktop and upload your Symbian package on it. This was pretty nicely integrated to Qt Creator since when running the recently remotely compiled application, Qt Creator would launch the Java application hosting the remote device. I was able to upload QuickFlickr on a remote Nokia N8 and see it launching. So it worked. But in the end, the latency of this service is too high for it to replace debugging on a native device sitting next to you. But of course, for verifying purposes on a variety of Nokia devices, this can be very useful for some.

I have also my doubts about the security. I was able to see and launch many applications that were clearly installed on these remote devices. I would not want this to happen to my unfinished application if I would be a company developing some application for OVI Store. I am not even sure if I would like this to happen if I am a lonely 3rd party developer developing my hobby project. So in the end, I think Forum Nokia would have to reset the devices to their factory state after each usage.

Qt Simulator

Last but not least there is the Qt Simulator target predefined in Qt Creator. It will run your application in a simulated environment and you can trigger some events (like incoming SMS, call or email) and see some predefined content (like contacts) on the device. This makes application testing during R&D pretty easy. If it would work, that is. Unfortunately I was not able to run QuickFlickr on the Qt Simulator in any of the simulated environments. The simulator started, the application was running in Qt Creator (I could hit breakpoints), but the simulator stayed empty. So what can I say - I hope Forum Nokia will fix this. Mac

Conclusion

As a conclusion I can say that this is the correct path for Nokia to go forward. This release includes all the necessary components for success; Qt Creator 2.1 is one of the best IDEs anywhere in my opinion, Qt Quick is amazing for mobile UI development and Qt Mobility will hopefully at some point deliver the easy cross platform middleware framework that Nokia is currently lacking. I think it just comes down to execution and speed. Something seems to be wrong when there still isn't official support for Qt 4.7 and Qt Quick on Symbian, but this technical preview of the upcoming SDK shows that the direction and the intentions are right. I just hope the official release will come soon enough with proper device support. Speaking of which, even if I would have had a Symbian device here, I think I would have not been able to use it with my Mac as a development device anyway. Please correct me if I am wrong, but if using a Mac, I cannot install the new Qt 4.7 packages on the device. So I am still out of luck. Remote compiler and Remote devices are nice for people with Macs or Linux as their development machine, but nothing will replace native development support. I think at point Nokia just has to bite the bullet and offer native toolchain for compiling Symbian packages on Mac and/or Linux and to offer possibility to install packages on the device from these platforms as well.
