developing mobile apps for research purposes & data collection

Essentially I want to create a mobile application that has users perform some tasks and logs the data of various interactions, including:

  • Answers to questions at the beginning of the app
  • time it takes them to complete a task from the start of a page
  • whether they clicked on certain objects or not, and how many times.
  • information about the device they are using.

I’m wondering what people with experience building these test apps do, generally? I’m ok with something I’ll have to hard-code, so long as there are guidelines out there that I can learn how to incorporate it. Generally, I don’t want to have to link an app up to an analytics tool that will cost me tons of money, as this is for basic research purposes.

Hopefully this was the right place to ask. I know it’s more “HCI” than UX but this seemed like the right place.

Android Studio – apps not allowed permissions to save files, can’t change either with Eiciel app

I’ve tried what seems to be everything. Changing permissions in the home folder to my user ownership. Installing the manager Eiciel it won’t let me allow any apps to do anything since everything belongs to root! I can’t do anything except via sudo and a terminal.

And I can’t find a way to login to Ubuntu Studio as sudo or any other way to grant permissions. How does one fix this issue?

I tried adding my username user to visudo, it seems to save files now but the permissions app Eiciel still won’t allow me to add permissions for any users to any apps. Geany located in /usr/bin/geany found with: locate -e geany from the root directory. Tips?

Remap ctrl AND use ctrl-tab to switch apps: double tab needed

I’m using gnome-tweak to remap ctrl (switching ctrl and alt). I then use the system settings to map ctrl-tab to app swtching.

When I did this first, it worked. As expected

But since upgrade and reboot, this now requires a double tab press before the switcher comes up. I.e. on the first ctrl-tab the tab seems to go into the application, and only when I got tab again, the app switcher comes up.

The two changes work fine independently, but when I combine them, the strange behaviour occurs.

Any ideas? Any other ways of switching keys outside of gnome-tweak?

Best practices: keyboard dismissal and button display in mobile apps

We have both iOS and Android apps with forms in multiple places, and are looking for an appropriate UX pattern for continuing when the form is complete.

Example: On the login screen, the user must type both a username and password, and then trigger the login action.

1) Should the login button “float” above the keyboard? Only when the last field is active? 2) Should the keyboard dismiss whenever one taps outside of it? 3) Should the “return” button in the keyboard say “continue” when the first field is active and “login” when the final field is active?

This seems like such a standard use case that the behavior should be defined and standard for both iOS and Android platforms, but I’m struggling with finding it documented anywhere!

What is the best way to secure web api calls from worker apps running on windows

I have a particular problem on how to securely call web api from machines that do automated data collection on documents. The computers that run code are windows machines and the server is a kubernetes cluster running on Linux OS. We use AzureAD for getting regular users on the web app and I know there is a device code login that could work but my problem is that the user needs to do the two factor auth manually when the token expires and I don’t want this to happen during the night when everyone is sleeping and the document collection workers to stop working. The worker machines cant be on azure due to software and hardver that is required to run it. I was thinking to store a certificate on azure key vault and then create jwt tokens with the client and use the same certificate to verify that token. I feel there must be a best practice for this but I don’t know. I think we could run the machines inside a vpn and the server too but I would like an extra layer of security for the api calls. If there was a way to use windows AD for this that would be grate but I am unable to find a recommendation for this scenario.

Power Apps form embedded in Power BI to update Sharepoint List

I created a Sharepoint online list that tracks cases. Users review and update cases through a power apps form on the site. I also have a power bi visualization that is querying the Sharepoint list to display graphs. Is there a way to put the existing power apps form into the power bi so that users can update the cases from there? I want users to be able to update the power apps form in the power bi and have those updates reflected in the sharepoint online list.
