Hi XiaoGuo, Thanks for sharing your experience! Qt version is an important detail indeed, as we want to offer the Qt Project's Long Term Supported version - the 5.6 series - as the version in ubuntu-app-platform. -Timo torstai 24. marraskuuta 2016 XiaoGuo Liu <<a href="mailto:xiaoguo.liu@canonical.com">xiaoguo.liu@canonical.com</a>> kirjoitti: > Hi, > I have created a Chinese blog at <a href="http://blog.csdn.net/ubuntutouch/article/details/53315941">http://blog.csdn.net/ubuntutouch/article/details/53315941</a>. It shows how to make use of ubuntu-app-platform to create a Qt-based application using content interface.

After some troubleshooting, I finally found the root cause of the problem. The ubuntu-app-platform is based on Qt 5.6.1 version. However, the Qt version on my desktop is Qt 5.5.1 >> As suggested by the blog <a href="https://developer.ubuntu.com/en/blog/2016/11/16/snapping-qt-apps/">https://developer.ubuntu.com/en/blog/2016/11/16/snapping-qt-apps/</a>, we need to install the stable-phone-overlay at <a href="https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/stable-phone-overlay/">https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/stable-phone-overlay/</a>. We need to do "sudo apt upgrade" and "sudo apt dist-upgrade" to make sure our Qt version is Qt 5.6.1. Then everything will be fine. >> Best regards, >> XiaoGuo >> >> >> >> >> On Wed, Nov 23, 2016 at 12:21 PM, XiaoGuo Liu <<a href="mailto:xiaoguo.liu@canonical.com">xiaoguo.liu@canonical.com</a>> wrote: >>> >>> Hi, >>> I just read a blog about snapping a Qt app at: >>> <a href="https://developer.ubuntu.com/en/blog/2016/11/16/snapping-qt-apps/">https://developer.ubuntu.com/en/blog/2016/11/16/snapping-qt-apps/</a> >>> >>> I followed the step, and I made my own project at: >>> <a href="https://github.com/liu-xiao-guo/rssreader_platform">https://github.com/liu-xiao-guo/rssreader_platform</a> >>> >>> The file size is dropped dramatically.
