Navigation module doesn't seem to be working for the last few days

Hi Steve, MIT App complains about version mismatch with this apk. Does the companion needs rebuilding?

-Thanks

[SteveJG]

@Pankaj_Mehta

The temporary Companion only works in live development . To build an apk users have to wait until MIT fixes the issue for an apk.

For Navigate to work again from the main server, users have to wait for MIT to release nb197 and provide a new Companion (2.71 perhaps).
MIT has a fix that works that will be released with nb197 . It is available on it's test server but you don't want to build an apk using the test server.

A month ago I speculated the Navigate 404 error would be fixed within several weeks. I was wrong. MIT is waiting for fixes to other App Inventor issues and features before releasing it. When will the fixed version be available to general users? When MIT is ready. I have no idea when.

In the mean time, users can test their apps with the test server or the temporary apk. Yes, it works fine.

Thanks for the useful info as always Steve.

Any way to run this standalone on the phone? I am working with a group of kids who want to demo their app at an event?

[SteveJG]

@Pankaj_Mehta

Any way to run this standalone on the phone?

Yes.

• Make a copy of the kids app.

• load this version of the aia to the test server https://ai2-test.appinventor.mit.edu/

• make sure you use Companion 2.70t1u as shown on the test server splash screen.

• build the apk using the test server

• load the apk to the phone using the resulting QR code

• the app should run on the phone I tried this using the test server and it works.

Try it. Good luck.

Thanks Steve. Was not aware of the test environment. Will test it out shortly

. I have no knowledge about which platforms provide this facility. I will be very thankful to him who will help

What exactly is your question ?

[Aramis_Garcia]

A mi me estaba fallando de igual manera el componente Navigation y buscando una solución escribí un programa en Apps Script de Google que visita la página de ORS y me devuelve los Points de la ruta y otros datos de interes. A este programa le envío las coordenadas de inicio y fin, visita la página de ORS y me devuelve los datos que necesito como json. A partir de ahí dejé de usar el componente Navigation que estaba dando problemas. Mi aplicación funciona de maravillas, como mismo funcionaba antes de que se dañara Navigation

Welcome @Aramis_Garcia

@Aramis_Garcia

My application works wonders, as it worked before it was damaged Navigation

Consider sharing your code where you use the ORS api code as a substitute for the Navigate control with the community. Post the required Blocks here perhaps?

MIT hopefully will post the fix to the Navigate error problem soon.

[Pankaj_Mehta]

That works a treat Steve. Many thanks for your help

[free_fire2]

Thanks Steve. Interesting that ORS works from non MITApp routes; you tried the web component and I tried python. Also, when using the MITApp route, my quota count on ORS is decremented which Free fire nickname makes me guess that ORS did serve the request but somehow MITAppInventor didn't route the response back to the app.

Saludos amigos.
Con mucho gusto comparto con ustedes mi script. Ante todo decirles que la función de este programas, más allá de solo suplir al componente Navigation, es seleccionar la ruta más corta entre dos puntos utilizando como medio de transporte un automóvil o bicicletas. El programa apps script recibe la información y selecciona de los dos la trayectoria más corta. La solicitud se hace con esta url. Además de eso busca el nombre de las calles en las cuales están ubicados los puntos de origen y destino.
Todo forma parte de un proyecto mayor, pero creo que con esto que les comparto ya pueden tener una idea de cómo lo hice.

Por otro lado, si lo que se quiere es solamente una via alternativa al componente Navigation, se puede usar el componente Web con la siguiente url: ORS

Cualquiera de los dos casos anteriores responde en formato json. Solo queda usar los bloques necesarios para extraer los datos de interés.

Espero les sea útil.

[SteveJG]

Thank you for showing one way to use the OSR without the Navigate control.

Translation:

Greetings friends.
I am happy to share my script with you. First of all, tell you that the function of this program, beyond just replacing the Navigation component, is to select the shortest route between two points using a car or bicycle as a means of transportation. The apps script program receives the information and selects the shortest path from the two. The request is made with this url. In addition, look for the name of the streets on which the origin and destination points are located.
It's all part of a larger project, but I think that with what I'm sharing with you you can already have an idea of ​​how I did it.

On the other hand, if what you want is only an alternative way to the Navigation component, you can use the Web component with the following url: ORS

Either of the two previous cases responds in json format. All that remains is to use the necessary blocks to extract the data of interest.

@David_B

Error is still there

Explain what you are doing. Are you using the test server?

When I use the test server with Navigate component, the error is gone See post #18.

Be aware. the main server is still not updated as of today 6/28/2024 Wait until nb 197 is released. or only use the test server.

. Using the test server and Companion 2.70t1u the following works

orstes3.aia (5.4 KB)

except when ORS does not have a tile showing desert tracks and tiles that have minimal data routing data. See the examples in the ortest aia.

Navigation component does not work. It throws 4003 an error message with a 404 page not found being in it. I think the Openrouteservice has updated their Web API while MIT App Inventor should update it accordingly.

[yu_meng]

Do you know how to report this issue to MIT App Inventor?

[yu_meng]

Look like the openrouteservice WebAPI below works. It must be an issue with mit app inventor
https://api.openrouteservice.org/v2/directions/driving-car?api_key=[apikey]&start=-96.7878912,33.34725&end=-96.7878912,33.24725

[Aramis_Garcia]

Take a look at this:

Navigation module doesn't seem to be working for the last few days

I have an app that was working fine till a few days ago but not fails with 404 error. I have created a sample app to test the simple map scenario with fixed coordinates and can reproduce the error in that: [image] The same coordinates work fine when I use python to work with OpenRouteService: [image] Has there been a recent change to the components interfacing with OpenRouteService?

[SteveJG]

See posts 18 and 30 in this thread.
MIT fixed the issue with Navigate on the test server in April . They made it available on the main server 7/7/2024. Use the new version of App Inventor available on the release of nb 197.

MIT fixed the issue with Navigate.

.Use the aia in post 30 to test it's operation. First fill in your ORS api code in the example aia.
