Ubuntu Touch Application design

[schankame]

I am a student and for a final project I am trying to create an application for my Ubuntu tablet running 15.04. I am trying to create a simple application to start with but two things keep happening. One my emulator keeps locking up and my entire machine locks up. The other I keep getting these errors:

• warning: desktop_Exec (app-test): found unexpected Exec with architecture 'all': ./qtc_device_debughelper.py

• warning: security_policy_groups_safe_app-test (debug): (REJECT) reserved policy group 'debug': not for production use

The debug policy group is automatically injected and should only be used for development. To create a package for the store use the publish tab!

• error: security_policy_groups_webapp (app-test.apparmor): found unusual policy groups: debug

I also included the show output file. Does anyone have any suggestions or can pint me in the right direction?

Thank you!!

I can confirm I have the same or a very similar problem. The Desktop version of my webapp runs fine in the Ubuntu SDK (Qt Creator), but when I try to upload the webapp to my phone for running it, first the Qt Creator locks up, then soon after the whole notebook blocks itself. I thought this may just be because I'm using an elderly HP Compaq 6735s notebook with 2 GB RAM, but who knows.

The other I keep getting these errors:

• warning: desktop_Exec (app-test): found unexpected Exec with architecture 'all': ./qtc_device_debughelper.py

• warning: security_policy_groups_safe_app-test (debug): (REJECT) reserved policy group 'debug': not for production use

• error: security_policy_groups_webapp (app-test.apparmor): found unusual policy groups: debug

I made the security_policy_groups_* warnings go away as follows below. The problem is in the .click package, which is (I believe) generated in the course of walking through the Create Project wizzard.

1. In the Ubuntu SDK (Qt Creator) open your project.
2. Visit your project's .apparmor file and make sure debug is not listed in the "Security Policy Groups", save the file.
3. In the menu bar choose Build -> Ubuntu -> Create Click package.

Afterwards, all build errors vanished.

However, I noticed the menu bar is not always there in the Ubuntu SDK, this may be a bug of the IDE, I don't know.
