Build a phonebook app using android studio

Similar to phone book, this app allows to add, edit and delete contacts which include name, telephone number and email. This app allows users to send and receive message, make a call and send email. The list of contacts is according to alphabets. In the menu option, there are status and search options. In status option, users are able to change their availability to busy by which all incoming calls will be blocked. *{At the same time, a message will be send to the callers saying ‘Sorry I’m currently busy, will call you back later.’} In search option, users are able to search for the contacts they are looking for instead of just scrolling the list of contacts. Importantly, I’ll need this app to include splash screen with text-to-speech at the starting and also to use sq lite and shared preference coding. *{} optional
