Unfortunately even though the Flex SDK is wonderful to work as a developer is really resource heavy on the phone, so it would be really forbidding on the low to mid range devices due to RAM and ROM requirements. I had to move to Native Android development where I have to familiarize my self since I have no previous experience developing for Android so that's the reason for the delay. Luckily I don't have to rework the plugin part or the Xml based protocol as they work fine so I just have to replicate the functionality on the native application. The native application seems to be really light on resources and I can also implement a few features I had in mind, like the option to lower the music volume on incoming call. Also I will try to implement the ability to change the song rating, since the android SDK has a rating control. The lowest targeted version will be Android 2.2 [API v8].
