Hello,
I'm an experienced Android developer and currently have 2 published applications on the play store and working on completing another application, I've completed many freelance projects and I'll have no issues working with you on this one.
I've read your project description and I've worked with the android media player before so I'm well aware of how it works and functions.
I've written several android applications in the past and have enough experience to comfortably adhere to design and programming recommendations.
You can view my portfolio to see some of the applications I've build in the past I always put in my best effort to assure maximum quality.
We will need to discuss in detail what exactly your project requires so I'll be able to assess what will be possible, please contact me so we can decide how to move forward with this project.
Thanks
