Hello,
Thanks for the invitation.
We understand that you want to develop a app for music store, which allow users to download music tracks, also should be able to pause downloads anytime, also download will stops automatically when network fails. Once the downloaded is completed following values are need to be saved in database which admin can track are userid, total size of file, time downloaded to start and finish, mobile no. of users etc.
We are the team of Java and PHP/Mysql developers. Our skills include Java, jquery/javascript, android/IOS/blackberry/symbian phone apps, API integration, HTML5, CSS3 etc...
We can provide you a developer who is having experience in developing these kind of apps and can develop one for you.
Let me know if you want to discuss further, we prefer Skype/IM for faster communication.
Looking forward to discuss further.
Thanks
