I am currently working on a project and would really like to include on my app how many times a switch has been activated and display this on my tablet! Can anyone help?!

Can you transfer Images from one screen to the other?

I want the user to upload and cut the image into pieces on a new screen and after that he can transfer it to other screen where he can use that image as puzzle pieces..

--

Just store the names of the pieces in TinyDB in the first screen then recall them in any other screen.

Alternatively, pass the names of the pieces in a list to the other screens with open another screen with start value.

You can use Texting component.

Also, you can use FirebaseDB component to create like a chat app. For FirebaseDB, see my blog post example HERE.

No aiSarter icon on my desktop.

Installed appinventor but no aiStarter on my desktop.  Windows 8 doesn't install it automatically - has to be downloaded from an app store but it's not available there either.  Degrading to Windows 10 then upgrading back to Windows 8 messed up my old start menu.  Shafted every way I turn.  Where can I download aiStarter from?

-- 

OK!  Uninstalled appinventor / deleted out old versions of the installer / re-installed.
Now I have the aiStarter Icon on my desk top.
The first time I used it I was told that the companion was out of date.  Went to the emulator and updated the companion, and now the emulator won't open.  The connection from appInventor just hangs.

What do I do next please?

--

Just to clarify; when I click to run my project through the emulator I get a message box saying the emulator.exe has stopped working.  I click on the "close program" button, then appInventor just hangs trying to open the emulator which has stopped.

I've just been to folder commands-for-appinventor and clicked on the batch file run-emulator and the emulator runs perfectly OK (so far as I can tell).  I just can't run it from appInventor.

Did you open a project at the AI1 web site and press Connect?

try to speak a few times "Pizza Margherita" to find out, which word combinations the speech recognizer returns as result... you will have to check for all these words, the speech recognizer is not very reliable to understand words exactly... also you might want to convert all words into lower case, the contains text block is case sensitive...

-- 

Thanks so much...you are very kind......i resolve it also with the word combination....it was a problem only of word........i would ask to you another think..... if i want to make Pizza Margerita 1,2,3,4 5 = 5 euro  and Pizza marrgherita 6,7,8,9= 6 euro......how can i make this function???????or if i want make Pizza margerita 2,4,6,8,10,12,14 (equal )= 6 euro ....and Piazza margerita 1,3,5,7,9,11,13,15(odd)= 7 euro.....how can i make this 2 function...???
