Fire base integration and functionality implementation

Voting app Update I want to update an existing voting app. It has to made online now using Firebase It is on the playstore. [login to view URL] it is used to decide the best candidates in a meeting. Current process is like : • Single phone is used to capture votes from all the people. • Admin creates the meeting. He enters the details of all the candidates. Name, photo, project title, role..etc. • He starts the voting process and passes the phone to audience. • Audience votes one after other votes in the same phone. • When everyone has voted, admin checks the result in the device by entering the password. Now it has to be made cloud based so that everyone can vote at the same time. Cloud database can be firebase or any other suitable platform. New process will be like : In the app there are two options [login to view URL] a meeting 2. Join a meeting • Admin creates a new meeting. He enters the details of all the candidates. Name, photo, project title, role..etc. • He starts the voting process. All the candidate details gets stored on cloud. A meeting id gets generated. He announces this id to all the people. • Audience can vote in their own phone using the app. They can “join the meeting” using meeting id. • Votes are captured and stored on cloud. • Results can be seen in admin’s device. Please go through the app and understand the requirement. Bid accurately to save time. I will give the existing source code and after completion I need the updated code as well.
