ejecute el al companiom desde mi pc y con el wifi y emule al companiom en mi teléfono móvil y llegue hasta la calle y me sale los puntos marker hasta allí todo bien
pero doy unas pasos mas allá y el wifi ya no llega
allí hay un problema
si se quiere que corra el app tiene que ser instalado con el apk para ejecutarlo con el paquete de datos
¿como podría corregir eso?
I expect the server will be again soon. You should be able to build the apk later today or tomorrow, then test with the apk installed with data. Good luck.
When you load the SocialDistancing aia, App Inventor automatically generates the CloudDB token default for the app to use MIT's server. See CloudDB. You do not have to 'customize'
The simple solution is do not use Screen2. The the tutorial app example now works on your Android. If you want to 'study' and make changes to the app; make a copy of the aia and study the copy. and read the explanation about how the app works After you have a copy, do your experiments.
Merci de votre réponse ce code m'a beaucoup aider juste il est conçu pour quatre utilisateurs
Et ça revient à mon problème
Je veux un nombre illimitée en utilisent l'application un marker est ajouté automatiquement sur la carte j'espère que vous m'avez compris
You will need to re-write the blocks code in order to handle unlimited users. You might consider that once a set number of users (three/four?) are on the same train, there is little point in more users reporting the location of the train?
n.b. you may find it easier to use Firebase, which will provide you with user authentication as well.
Oui un seul utilisateur suffira pour moi le nombre d'utilisateurs comme une source de foule
Un partira sur voie1 l'autre sur voie2 chacun ça destination
Es ce que c possible par générateur UUID
You cannot use the tutorial example as it is. Either modify the example to use Runtime Markers (it presently uses Designtime Markers) or you might add a number of Designtime Markers and hide them until they are needed as new users join the postings.
There are several possible ways to use Runtime Markers to add a new Marker when a new user installs the app.
In my opinion the use of multiple Runtime Markers involve complex coding. I do not have an example with multiple Runtime Markers. An app using a Runtime Marker instead of DesignTime marker for a single user works without much additional coding.
What you do depends on whether each user uses a static location or whether the Marker location needs to reposition when any user changes his/her location.
What have you tried? Get your app to first post YOUR location. Once you are able to do that you will need to develop the logic to permit and use the locations of others.

After you have a copy, do your experiments.
