Android Calling App

Mobile app android only

Compatible with older versions of android

The goal/usage of the app will be :

0- there is a database (phpmyadmin) containing good or bad phone number [id,phone_number,type (sms/phone),status(good/bad), rank]

1- when The user click on the launch app button

2 - the app make a GET /valid_phone_number

3- the api returns a phone number which is marked as "good"

4 - the app launch a phone call using this number

4.1 - if the phone call is successfull (the call is not immediately hung up / the duration of the call is more than 10 seconds) THEN the app make a new GET to the api in order to pick another good phone number AND THEN, the app create a conference call with this new number

4.2 - if the phone call fail (the call is immediately hung up/ the duration is less than 10 seconds) THEN the app make a POST or PUT to the API in order to set the line containing this phone number as bad.

5 - the goal here is to always have about 6 differents phone numbers in the conference. 24/24, 7/7

That is, :

- WHEN a phone call fail because the number was detected not good, the app immediately try to make another call, and add this new call in the conference.

- WHEN a phone call which was good, finally ends because it reached an existing telecom operator limit (1or 2 hours for example) THEN the app try to relaunch this call (if it works then ok, else the app can set it as "bad" using the api)

6 - Please also provide a mean to stop the calling process : it can be the hang off button of the phone if you use the default phone of the smartphone, or a button on the app screen.

Note that here, there are two main features to build :

- the one in charge of : making a first call and then continuously adding a new call in the conference if there are less than 6 ongoing calls

- the other in charge of : calling api to get or update phone number stored in a database .

preferred language : java for the mobile app or flutter / php for the api (because i need something that can be deployed easily)

Also, provide working source code to me + installation process.

Thank you for your help and don't hesitate to request more info.
