Arvyla Player V1.8

This is actually not an upgrade of the arvyla player but a version that can be installed from version 1.5 (cupcake) of android and above. The previous versions of arvyla player were able to run from version 1.6 (donut) and above.

This was a request from a friend running cupcake on his phone :-).

Arvyla Player V1.5

Well there is a saying in the world of open source. "Release early, Release often". Arvyla Player v1.5 for Android is out and now you have the ability to set as Ringtone or Notification your favorite "Arvyla" sound.

In the next release i will try to add more sounds in the application.

Finally i uploaded Radio Arvyla Player on android Market :-). This is a pet application that i created, in order to learn how to program on the android platform. I hope you enjoy the app.
Since i only have a G1 phone to test my apps, comments about the application running on other phones are welcomed.
