Backstory: Like most countries in the world, we've been hit hard with the coronavirus. Unlike most countries in the world, our country does not have an app that tracks the virus. We can go to a government website that gives us an outdated summary, but that's about it.
Issue: we have a popular web-based retail site, and we created a web-based map that tracks coronavirus-confirmed cases. We were also in the process of creating a mobile app that provides info on the virus, but then apple store and google play started blocking apps related to this virus unless it's approved by the government. We've been trying to get approval, but it's an uphill battle.
Since our web-based app tracks all cases in real-time, is it possible to send some type of notification to a mobile phone? For example, a notification would say something like "Another patient has tested positive. Please visit our site for more information".
I've seen services like Amazon SNS, but I'm not exactly sure what these services do. I was also considering web push notifications, but I've read that safari doesn't support this. I've also read that Firebase can do this, but I'm not sure how.
I guess the question's really a yes/no question: Is it possible to send some type of notification to an iphone or android phone without installing an app? This wouldn't be spam since the user would approve the notifications received.
You can send an SMS message if you know the device's phone number. You can use FCM on a web app if the user opts into the notification after visiting your site. Otherwise it's impossible if you don't have an app installed that's designed for receiving and displaying notifications (for good reason).
I suggest researching your options before posting to Stack Overflow - it's for programming questions, not for soliciting ideas for products to solve a problem.

I need to make around 1000 android apps with same code base but different names, logos, splash screens,images . using android library will solve the issue? One google developer account is sufficient?
Google has recently cracked down on template apps, and you will likely have apps rejected and get your account banned if you attempt this under a single account:
Apps that are created by an automated tool, wizard service, or based on templates and submitted to Google Play by the operator of that service on behalf of other persons are not allowed. Such apps are only permissible if they are published by an individually registered developer account belonging to the user of the automated tool, not the operator of the service.
You may be able to make this work for now if you create a new account for each app that you publish; however, there is no guarantee that Google won't change the Play Store terms of service to prohibit this as well.
It is not a good practice to do so.
If each app uses the same source code but different ressources, you should offer customization options within the main app.
You won't have good dev feedbacks by polluting the market this way.
With customizations, you can reach as much users as you would with a 1000 apps, because you could meet their needs properly.
Take a look at Inn-Apps billing in the official Android developer documentation...

In this App (Desktop Notifications), they are sending notifications from Android Phone to their Chrome Extension.
I want to do the same. How can this be achieved? I am looking for direction on what tools I need to start researching (as I am directionless to start)
I do not have a server, so do i need to use Google APp Engine? Should I be storing the notifications in Google Cloud Datastore?
Is GAE the right approach here?
(Note: Indie developer here, so preferably looking for a free solution, at least until the app gets lot more users)
It's a partial answer, but it's longer than a comment.
There are two APIs in Chrome for notifications:
1) The older chrome.pushMessaging API, using "Google Cloud Messaging for Chrome".
Maximum payload length: 256 bytes
Maximum subchannels: 4
Maximum API requests per day: 10,000
2) The newer chrome.gcm API, using Google Cloud Messaging
GCM is completely free no matter how big your messaging needs are, and there are no quotas.
(Quote from http://developer.android.com/google/gcm/index.html)
I think only the second one is two-way.
As far as I can tell (and I am not an expert in this!), they do not require a separate server to handle the messages. Both your Android app and your extension should be able to send a message to a Google endpoint and it will be broadcast to intended recipients.

Hello I am trying to implement an feature in one of my app so that it can be installed only on one device i guess trying with Device ID is one method Or are there any other methods to do so.......
If you are putting this on the Play store, users can always download any paid software again, as long as any device is linked with the same Google account used to purchase the app. This is designed to stop people losing apps should they get a new device etc and paying for it multiple times.
After reading your comments I believe what you wish the app to do potentially breaks Google Play TOC's. That said, you have not really described what you want to do well enough.
You could require the user to register with an email address before using the app. Maintain a database of emails that have been used to register the app and if an email has already been used, block them.
Note that while this is technically a solution to the question you asked, setting a limit like this is just going to irritate your users and is more likely to cause sales to go down (the few who buy will leave negative reviews, causing others to not buy), not up.

This may appear counter intuitive to normal posts here, but I was directed to stack overflow as the forum for questions from the FB developer site so here goes!
I'm a network engineer assisting a local school district with some network upgrades. Part of the upgrades involved setting up a web content filter (Untangle), which works great. For various reasons they want to block access to facebook from the school's network during normal school hours. The normal and mobile websites are blocked, but the web content filter doesn't block the mobile app (since the requests aren't coming from a browser the traffic is analyzed differently).
I've opened a ticket with them to see if there is a work-around, but am looking for a way to block the mobile app from accessing facebook until they have a solution. What IP/hostname/ports can I block on our Cisco ASA to stop traffic to the mobile app site? Is there an easy check the app does for connectivity to FB that I can intercept and "trick" it into thinking it doesn't have network access?
These are personal devices, so we can't make changes to them, and yes I realize that technically they could still get access via their mobile provider.
Thanks in advance for ideas and any suggestions!

Do i need to pay a developer's fee of 99$ per annum if i want to list my web app on the apple web app store, or any other place for that matter (android etc.)?
Can i ask user to come and pay for new features on my site through this web app? will I be breaching some archaic policy by doing that?
This web app is complete on its own but user might want to have extra features which come at a price of course!
Which merchant is the best for my basic needs. paypal comes to mind but is it my only option?
this is my hobby. I have a separate day time job which does not involve software development. what do i need to do as far as paying taxes (if any) is concerned. am i liable to pay taxes?
I do not want to create my own company etc. just because im developing this web app.
By the way, if you intend to reply on tax-related questions, please understand I reside in England.
Since you're doing a web app I believe that you can get listed in the Apple Web App listings by just being a safari developer, which is free. Im not sure that android has such a place or Windows Mobile either which means your going to have to do a lot of the marketing of your web app yourself.
In this case, you are not going to be bound by any of the "Laws" that govern the App Store, Android, or Windows Marketplace. You can charge whatever you want to "featured" functionality and nobody will scoff.
As far as your taxes are concerned. You should talk to an accountant about any income that comes from the app as well as having to charge any sort of sales tax.
Hope this answers your questions. Good luck with your app.
