Dear Dave,
fellow Inquisit users,
we would like to administer an experiment via the webversion of Inquisit using tablets. More specifically, we are using the Samsung Galaxy Tab A7 with the most recent version of the mobile app (Inquisit 6). The last updated was downloaded by us yesterday.
The experiment is working fine on various computers and an iPad (also using the most recent version of iOS and Inquisit 6).
However, we are not able to get the experiment going on the Samsung tablet (on six Samsung tablets, to be more specific). The first script starts, we see the first page, and then it just aborts as soon as we touch on the first “Continue” button in the form of an arrow.
Here is the link to our experiment where mutated vowels are integrated: https://mili2nd.co/qr3b
Here is the link to our experiment without any mutated vowels: https://mili2nd.co/rr3b
Attached, please find a picture of the screen after abortion.
Do you have any suggestions on how to get the scripts working on the tablets? Could this have something to do with the encoding schemes? All scripts are .iqx files and should be UTF-8 encoded.
We’d be happy about any suggestions!
Best,
empra-uulm

Remove the computer.macaddress property from any and all of your data elements and try again. Newer versions of Android will not allow accessing the MAC address, other platforms or older Android versions will.

Dear Dave,

thank you so much for your help!

It is working on the tablet now, but only in the online version. If the script is downloaded, the app shows that the offline version is available (the box is checked).
However, when the tablet is not connected to the internet (wifi disabled), the following error message occurs after the start page of the test: “Inquisit encountered an error while executing script xy”.
If the tablet is connected to the internet, the complete test works without problems.
Here is the current link to our experiment https://mili2nd.co/vr3b

This is somehow curious, as this wasn't the case several weeks ago.

For our study we need to ensure offline testing is possible.

Any ideas?

Best,

For offline use, remove the computer.ipaddress property from the <data> element as well. Android is pesky and screams bloody murder when the device has no IP assigned b/c WiFi is disabled.

Ah, ok! Thank you for the solution. We will try this asap, but for some reason we are not able to login onto the millisecond homepage right now. We are getting a 502 Bad Gateway. Do you have an idea when this issue might be resolved?

Working on the login issue, I'll update this thread as soon as it's resolved.

The sign-in issues should be fully resolved by now.

Dear Dave,

yes, thank you. We were able to sign-in without any further problems.

We now have one more question however:

There is another experiment, which we would like to administer offline using the same tablets. We've removed the computer.ipaddress and computer.macaddress property from the script. However, the script does not run offline on our tablets, although it works smoothly if we are connected to the internet.

We have made sure that the script is downloaded onto the tablets (the box on the left says "check"), but it doesn't even start.

Maybe you could help us once again :-)

I've uploaded a fixed version to your account. Put the experiment back into online mode, start it once online, then put it back into offline mode. This will pick up the changes and the thing should run then.
