I have created an app for my IOT project by using MIT app inventor, it works fine In AI companion , but when I installed its apk file in my phone then the app is not Starting

ThreePhaseIOT.aia (3.2 MB)
here is the the file

When I run your project in companion I get:

Error from Companion: For a custom firebase host you must first set your authentication server before using authentication features!

Following this and searching for a given phrase in the community, we can find, among others:

Create a new project using the US central server. The Firebase component will not work if you use any other firebase server.


I hope to help

Your Firebase project needs to be on the US-Central server for the Firebase component to work.

Explain to me more please

OK, looking at your first screenshot, your firebase url is incorrect.

It should be: https://<project-id>.firebaseio.com/

You will see this above any data you may have in your firebase console


Add this link Do you mean something else?

That is it.

It was added and so far an error has occurred

What do I do

Did you put a / at the end ?


yes

As you should be able to see, your firebase url is still wrong....

it should be this:

(with a / at the end)

You can also delete the Token, leaving it blank, it is not needed....


The problem is still there. Can you log into my account and solve it?

You still have not correctly entered the firebase url!

Where is the frtebase URL? Show me a picture

You showed it a few posts up
