Write an Android application

Automatica Conference System. Good day. I need an Android software for automatic conferences. The program shall have the following characteristics: 1. It must be installed on Android (any version) 2. It will access a site example: [login to view URL] 3. The site will answer the request: Option A: "#200#" means that this Cellplhone can not use the program. Option B: #6# our #2# (number of simultaneous calls, will be 2 or 6) 1.9541231123; 2.9541211123; 3.8761223123; 4.9871928364; 5.1928736548; 6.7617182873; These numbers of option B are the numbers that the phone will call, he must put all the numbers in conference, 5 numbers at the conference + 1 active connection. When a connection is lost, you must reconnect this forever, until turned off. Every 1 minute, it will make an HTTP POST to inform how are the calls Example: https: //[login to view URL] IMEI = 987656789876545678 & action = updade & 1,123 & 2,123 & ... 1 being the connection and the 123 call time. The site is FIXED and opens via HTTPS. The panel of the phone / program will display: Server: conected Status: Active (Total today: 04:12:12) Line 1: Active: 00:40:00 min Line 2: Active: 01:12:12 min Line 3: Dialing ...
