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.

Hi,

I am unable to view the video/demo on Firefox.

There is still the issue that the emulator will hang on files, exe's, dll's,resource files. AFAICD it keeps hanging on to resource files (especially the reg ones) and you have a change of one in three that it keeps hanging on an executable. A complete restart is then required.

What does help to speedup though is to turn off all logging. That makes startup half as slow (it is still slow, it is not yet fast).

Hi mayankkedia,

It's just an embedded YouTube video, should work (and does work at least for me) with any browser. See it at http://www.youtube.com/watch?v=D9IeE-F-4yk

Hi Sander,

you are right, in some cases the files do get locked but that would affect mainly my next "trick" video, dealing with rebuilding a project. Also disabling the logging will speed up the loading indeed and whenever not actively used developers should turn it off.
