Native App for both iOS and Android devices to download and play audio and video files from a membership web platform

Needed: A native app (written for iOS and Android devices) that would allow the end user to download and play media files from a membership-based web site. Basically, this concept would be similar to an audible clone. Basically, the app will have three views: 1) A login / authentication view (hidden) 2) An Audio view (for audio content) 3) A Video view (for video content) Upon authentication, the user would automatically be directed to the Audio view (by default). From there, the audio files would be grouped by language (English or Spanish), then by the most recent (current month they were made available) or by archived content (older than 30 days). This data (in addition to authentication data) would be provided by our internal website database (MySQL). Once a user selects a particular audio, the file is retrieved (downloaded) from our secure server, and placed within the app directory for playback at any time. We want to utilize this method to eliminate the need for streaming and Internet connectivity (in order to save bandwidth when traveling, etc). Developers must have a firm understanding of the following concepts: Objective-C Google Android PHP / MySQL CSS 3 XML Python Audio codec will be in MP3 format Video codec will be in MP4 (H.264) format. All deliverables (excluding Artwork or icons) must be produced as "ready to submit" to the Apple App Store and Android Marketplace. This is the main gist of the app. More details can be provided upon request.
