There is no stable public API for uploading apps to the store, no. Soon, any uploaded packages will require the author to sign them with gpg as well. Automating signing of your packages in a CI, would mean you'd need a private key with no password, and getting that key into a CI system may mean needing to have it published in a public location, thus ...

The LocalStorage documentation says, "Database connections are automatically closed during Javascript garbage collection." This makes me wonder if the connection is closed at the end of the ...

Ubuntu components include the StateSaver capability. This allows QML properties to be saved at program exit and restored at restart. For each element with properties you wish to save, set the StateSaver.properties property to a comma separated list of the properties that should be saved. However, there are two enormous limitations of the StateSaver. ...

Ubuntu's app lifecycle policy prevents any app from running in the background. Only the currently active app on the screen is allowed to use the devices resources, any app open in the background is suspended.

Add clip: true to the UbuntuListView. By default, QML objects have this set to false, which allows them to draw outside their allocated rectangle. I assume this is an optimization, since it allows the renderer to avoid calculating clipping for each element. Most QML objects only draw within their allocated rectangle, so you don't notice this. But list ...

I'm actually the developer of this tool and this bug is caused by an unexpected change of server infrastructure. The fix is waiting to be deployed by a team from Canonical who seems to have its plate already quite full. Thanks for your patience. Also, you can find a working version at http://developer.staging.ubuntu.com/webapp-generator/ :-)

I was using an outdated version of Ubuntu SDK. When I upgraded to Ubuntu 15.04, the SDK ppa was disabled, and I didn't receive further upgrades. After enabling the PPA again, I had to do a sudo apt-get dist-upgrade: Unpacking qtcreator-plugin-ubuntu (3.1.1+15.10.20150720-0ubuntu1~0vivid1) over (3.1.1+15.04.20150421-0ubuntu1~0utopic1) ... Now the ...

Nathan Osman's answer is great, but Ubuntu SDK team PPA (ppa:ubuntu-sdk-team/ppa) provides only Qt 5.0 for Ubuntu 12.04. If you need features from newer Qt versions you can use the new PPAs by Stephan Binner for Precise and Trusty. He created PPAs for all Qt version starting from 4.8. In order to not mess with Qt system packages, these PPA packages are ...
