Complete my App which I've almost completed

I was working on a project which is simply a one page app. It'll be a chatbot app in which we'll be integrating the Dialogflow API. It's not gonna be a big task as the code in [login to view URL] file would hardly be having 40-50 lines. Yes, I was thinking to code it myself and I almost completed it. But then, I thought of hiring a developer with more experience. WHAT I NEED IN THIS APP EXACTLY : 1. The app can listen to what I say and then use Dialogflow API (I'll be providing you with Client Access Token) to return an answer. 2. A decent interface where we have one "mic" icon which can be pressed to give the audio input. A field to type the input in text form. A "TextView" object to return the Dialogflow API's response. And, a decent background. 3. The name of the app at the top of the interface. 4. A small Created by "MyName" on the bottom of the interface. DIFFICULTY LEVEL OF THE PROJECT: The code is not gonna be too long. It won't take more than an hour for an experienced developer to complete it. There are a lot of resources on web which readily provide every bit of code for this in which you only need to do slight modifications here and there. Also, I've completed most of the code and I'll be giving you my code files. HOW I'M GONNA ASSIST YOU WITH THIS : Well. I'll be giving you the code that I have written. It's compiling perfectly. It has a very basic interface (It has a "Listen" button which can be pressed to give audio input). Although, due to certain Runtime errors, the "Listen" button is not working. Also, the app crashes at times. Moreover, you can check it yourself, what it already has and what it needs to have. I'll be providing the source code as soon as the deal is done. SUMMARY : I'm working on an app which I've almost completed. Now, I want someone to give it finishing touch according to my requirements. ATTACHMENTS : I'm attaching a screenshot of what my app currently looks like.
