[SOLVED] Single instance applications on N950

matrixx

@Alicemirror: If you are creating an application with the "Harmattan Application" template on QtCreator, you don't have to care about those lines Tomma mentioned, they are automatically added to your .pro file by QtCreator.

Instead, if you are porting an existing application and want to use your original .pro file, you need to add those lines manually to be able to use the single-instance invoker.

That might be a good addition to the wiki, if someone wants to port apps without creating a new project template and copying over existing files of the project.

Alicemirror

@matrixx: thank you for the precision. In effect the first application that I have created with the template had not this omission, but the problem of the export appeared only at the end of the solution of the qt-complex project ported from a first symbian version. I should add tnis to the wiki page.

I am also planning to write a page with the elemts that should change between a symbian and harmattan QML application using the two different imports of the new Qt Quick components for page navigation and page stack management.

Many thanks

Hi
Alicemirror I followed instrution from here -http://developer.qt.nokia.com/wiki/Single_Instance_Harmattan_Applications#57bd2611a5f660693bc0b0d96860058e
and changed my desktop entry as follows
@[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
Terminal=false
Name=insulincal
Exec=Exec=invoker --single-instance --type=e /opt/insulincal/bin/insulincal
Icon=/usr/share/icons/hicolor/64x64/apps/insulincal.png
X-Window-Icon=
X-HildonDesk-ShowInToolbar=true
X-Osso-Type=application/x-executable
@
insulincal is my app name.
I still get multiple app launches in N950 [on remote data access - I am still waiting for my device]
Can you pl check what is wrong above ?Thanks

@senu188
For some people mere recompiling fixes the issue, but at least I needed to do also this following workaround step:

Edit rules debian packaging file adding a space after MAKE, but remember to preserve tabs in the file, otherwise it will break.

senu188

Thanks I will try that and report if [hopefully not!] there is a problem

Alicemirror

hi senu188,

following the wiki page the described method includes also the suggestion of matrixx.
What I see in your code is that in line 7 of the post above there is the repetition of Exec= that is an error. Please try again correcting this bug and let me know if it works.

Cheers.

@Alicemirror
I believe someone has been modifying the wiki page, cause the "rules hack" is not there.

I immediately removed one 'Exec' as mentioned in my similar post posted separately[http://developer.qt.nokia.com/forums/viewthread/8687 ]. I am now trying to change the 'rule' file but I seem to have broken the build. I am trying again. The wiki page doesn't have anything about 'rule' I guess someone edited it off. Thanks will try and report

@matrixx

Mistery solved !!!

Please take a look to this post: "Wiki pages edited without control":http://developer.qt.nokia.com/forums/viewthread/8699/

Now the page is complete again. Please senu188, check if it works fine.

Thank you.

I did the following in 'insulincal.desktop' - insulincal is my app name
@[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
Terminal=false
Name=insulincal
Exec=invoker --single-instance --type=e /opt/usr/bin/insulincal
Icon=/usr/share/icons/hicolor/64x64/apps/insulincal.png
X-Window-Icon=
X-HildonDesk-ShowInToolbar=true
X-Osso-Type=application/x-executable@

The deb is built but still multi-instance so

I added a space after $(MAKE) in 'rules' file
@
$(MAKE) INSTALL_ROOT="$(CURDIR)"/debian/insulincal install

I get packaging error
Packaging Error: Command 'c:/qtsdk/madde/bin/mad dpkg-buildpackage -nc -uc -us' failed.Exit code: 2
@
I tried in 2 ways to add space-

I just add a space using spacebar in rules file inside Qt creator
I copy the rules file and paste it in Notepad, add a space and again paste that in Qt creator and rebuild
In both cases I get error. Is there any other way to add space so build will be proper. Thanks for help

Alicemirror

Sure you get error.

The problem is just there: the rules file includes special characters i.e. tabs starting on every line and - I think - linefeeds instead of cr/lf at the end of line. The fact is that you should edit anyway this file with a binary editor else when you save it some essential character is lost.

I use Mac with a binary editor, but I am sure that you can find some opensource editor in windows. Wincommander for example has a hex editor and binary editor and other files too. you can try to send me this file (those original working) and I edit it for you. When we are sure that this is the only problem, you search for an adequate program.

Alicemirror

Sorry, I read again your post.

If you open the rules file in the editor then try in any other way - correct or wrong - you loose the original formatting so the file remain fake at all :)

Please send it to me so I try with one of mine that is working recovery the special characters.

matrixx

I edited my rules file with QtCreator. Before opening the file, I changed preferences to use TABs instead of spaces.

Alicemirror

@matrixx

This is interesting, I have not trusted in Qt creator. If it is sufficient to set how to manage the tabs I'll use next time I need. Thanks.

Hi Enrico,

Please excuse me for the delay in my answer. I am using Qt SDK on Win XP.

Cheers,

Hi, Leon.

Does the method works now ?

As a matter of fact, if after the rules file edit you have errors this means that edit went wrong. This is a thing I am almost sure.

Yes, following the advises that I found in your discussion with matrixx I have managed to publish my app "location2sms":http://store.ovi.com/content/168861 for MeeGo Harmattan in Nokia Ovi Store. Thanks again :)

Alicemirror

Well, I am happy for this. Now the wiki page is restored to its original content.

yazwas

I've read thru all of these pages, and also the wiki, and changed my app but I cant seem to make it run!

This is the line in the rules file
$(MAKE) INSTALL_ROOT="$(CURDIR)"/debian/emirates247 install

in the .desktop file this is the content
[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
Terminal=false
Name=Emirates 24|7
Exec=invoker --single-instance --type=d /opt/emirates247/bin/emirates247
Icon=/usr/share/icons/hicolor/64x64/apps/emirates247.png
X-Window-Icon=
X-HildonDesk-ShowInToolbar=true
X-Osso-Type=application/x-executable

Now this make the app's icon shows correctly, but when clicking on it, it only opens a black screen and it remains black.

any suggestions?
Thanks
