android tag editor

It is my first time building an android 开发者_如何转开发app. Was wondering firstly, if there are demos that exists which could help me to build a media tag editor (form to edit mp3 files). I would also like to know how to populate the sd card on the emulator. Any help on android would be good. Thanks all!

When you create your AVD you can tell it how big you want the memory card to be and then you can use DDMS to copy files over to it. There are pretty good explanations on how to do this on the Android website.
