i have strange errors in different projects which already run as app on my device. I opened one of them to extend functionallity. Emulation via USB does not work anymore. Sometime I get errors e.g.
Project 2 (did not change anything... only opend the project)
This occurs in different projects. I did not change anything. Still tried to open them as comparison to the actual one I wanted to extend. All tested (opened) projects have problems which was not in the past. As I said... the apps are running on my device. Table with Android 13.
What do I have to do to rebuild my apps in Android Studio? Is there a simple way to do that (i believe not because exporting is only possible as a compiled apk)? I use App Inventor online... only have AIStarter on my computer and for emulation I use the USB connection. Always scan the QR Code is no option.
But also the inbuild emulator does not work any more and AI Companion (via Wifi and QR Code) is also not working. It seams that there is suddenly something tangled in my projects. What happend?
thank you for your reply. I save Projekt 2 under a new project and also change the name in properties. Installed it. No errors or warnings while compiling and also not in block view. the app works and sends date via bluetooth to ESP32 after granting the permissions.
The error in AI2 Web UI regarding label1 still occurs. No kind of emulation works.
I installed the one from your link. After that there was a message that the version is outdated or not vaild). I was prompted to scan a new QR Code to install a newer version. Nothing is shown on the screen. Via USB all ist starting but there are no elements (buttons ...). the screen is empty.
AI 2 Version of the companion on my tablet is 2.73au after the update procedure. The version from your link was something else but it did not work as described (invalid / old version)
I am lost. Due to the fact that I have no idea for these phenomena, I don't know what to do. I'm afraid that the damage will get worse no matter what I do now.
The only thing is an update on tabled what i did some days ago but these should not be the reason for the strange mesages in AI2 regarding missing labels or wrong VertifcalAssignments. Espessially because the projects compile and seem to work (at least the one which i testet - project 2)
Unfortunately it does not work. I installed the version from the link which is 2.73t6u. Now the popup regarding out dated version did not pop up (???). One time I could emulate the copy of project 2. Then I tried another project (copy) which does not work. Then I tried again project 2 which worked some minutes ago but now it dont work anymore. It is not stable and I have no idea for the reason. All in all worst case and not the best prerequisits for what i planned for holiday
Some days ago there were problems with the server. Could not compile any project. It works only after some tries. I ignored it and tried again a few day later where it works better.
Im not sure but there must sometings be happend which has corrupted my projects and damaged something regarding emulation.
As already mentioned, this is a problem with Companion. Install the trial version of Companion, a window will pop up when starting, click NotNow. And it should work.
Yes but this popup does not come up any more. The first time I installed the version provided by @TIMAI2 this popup comes up and i unfortunatly updated to the official version. After the hint from you i installed the "special" version again. But the popup did not come up again.
So... because i can believe this all I deinstalled all and installed the version from @TIMAI2 again. The popups come up and I chose "NOTNOW". It works now when I connect via AI Companion and QR Code. Thank you for that.
The bad is, that I am now at the point were I was at the very first beginning of using AI2. As a still beginner I have to test a lot and always scan the QR Code is not very pleasant / efficient.
Any idea what i can do that it works via USB as it was until a few weeks ago? Maybe I stell have to wait for a bug fix (if it is one - I do not know)?
I do not know how to make a video. But there is nothing special what happens. All went as it was in the past. Establish a connection... popup "wait some seconds to ensure all is running..." then an empty screen comes. With AI Companion this screen can be seen for a short moment and then is filled with the screenelements. The last step is not done when connecting via USB...
@Anke Can I ask you in which way you use the AI? I use on PC only the AI starter and AI via Web. Small installation. I still have the problem described above. Now I think about to install the total package which can be found here somewhere in downloads with approx. 1.5GB. But I am not sure if this brings me benefits and if this may solve the problems.
I also think about to install ADS. It seam to be possible (tutorials in web) how to recode the AI blocks there. But what would be with the different free aix extensions i use e.g. vertical slider or some extensions from taifun / timai (helper tools like keep the app on, suppress warnings and so on). I think that in case of using ADS I can not use them.
Is there any recommendation or would you think that the large installation of AI2 locally on PC would be helpful?
