Storing Data across different apps

I am creating an app where users can see a list of announcements made by other people. I have it so that when people log in on a screen they are able to edit text boxes making an announcement. How can i get it so that is sent out to all other copies of the app. I am currently using a fusion table which doesnt seem to be working, so are there any other ways to accomplish this?

-- 

someone who wants to announce something sends an INSERT statement to the table

and all user send a SELECT statement regularly to the table to receive the news

you might want to elaborate

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

Okay, but do you know if there are any other ways to do the announcements without using the FirebaseDB?

-- 

You can use TinyWebDB to store announcements. Then when app starts, read TinyWebDB to get announcement data.

Other alternatives are using server php scripts that inserts/reads data to/from backend database like MySQL

you can use any server database

I am using the tinywebDB how could i get it, that when it shows up on a screen how can i get it so that users can shuffle through different announcements?

-- 

On TinyWebDB, see if THIS helps.

I don't know if i stated my question clearly, but what I meant was that I have one screen where people view all the announcements. How can i get it so that they can view different ones from the tiny webdb if people are still going to add more announcements
