Android Call Track APP similar to CallTRack

Hello please BID only if you understand the requirements bellow and you can develop those requirements in the budget of your bid. We need  an Android native APP that has the following functionality, in big lines it is a small integration with our crm that will allow authenticated users to sync their calls from a mobile phone to crm. - the interface looks like in the image below, and adds extra 3 more fields , username, password, crm url [login to view URL]   - on incoming call standard event on mobile phone, a request (rest request or curl or any other format) will be sent to our crm (url defined in settings as above) The request should contain relevant information as caller phone number and other call information (as much as possible).-If call is being answered, on call end, a new request (rest request or curl or any other format) should be sent to the same url with call duration and some call id that would allow us to identify in backend which call is being finished.-similar to incoming call we need to track both outgoing and also missed calls, so for outgoing calls, we need a rest request on call initiation and also one request when call is ended with information as held/not held and duration in case of [login to view URL] missed calls we do need a way to be tracked in crm as well. PLEASE BID the amount you ask for this development,we require source code and also .apk to be installed on mobile phones. BID only if you fully understand requirements and you can deliver our requirements within provided bid.
