I have to admit that I was very excited when Steven and Victor
released the first android package for Csound, but once I started
using it I found it quite frustrating. Editing code on a phone is not
really an option. On a tablet perhaps, but I certainly couldn't see it
working on my Galaxy S3. I think it's real value is as a sound engine
for Android apps. I might get shot down for saying this, but it blows
pdlib away in terms of functionality. With the right marketing I could
see it becoming one of the standard sound libs for Android.

I agree that for phones, at least, the best application is as a sound engine. Still, if anyone is patient enough to
edit text on the phone, it is nice to enable it.

Hi Michael,

I think it's great to see these changes: thanks!  I think too there's
a lot of opportunity for mobile/desktop workflow integration.  While
editing a lot of code can be tedious on a phone, I definitely see
tremendous possibilities where the phone becomes a part of a larger
workflow.  One can start a project on the desktop, do some
modifications on the go, and synchronize between the two.  At least,
this was a design goal for me when I was doing some drafting of ideas
for what a Blue Mobile would be (I had put that idea down for a while
to work on other things, but this is inspiring me to think about it
all again).

Beyond this, another idea I had was a generative music player where
the pieces were CSD's, and the player could be implemented on Mobile
as well as Desktop.  I had a dream of totally portable generative
pieces that would be as easy to load as using a music player (i.e.
google music, iTunes, etc.). I had the thought of profile support, so
a CSD could say, this is built for quad, for ambisonics, for etc. and
the player could support certain profiles.  It'd be neat if profile
conversion could happen automatically too. For example, a piece that's
set for ambisonics could have player options for HRTF and Stereo to
play, or on desktop with multichannel have player decoder options.  I
think something like this, especially with an option for mobile, could
be great for the distribution of music works that don't have standard
2-channel, fixed medium requirements. This could be a very interesting
thing if we had metadata fields for author, year, album, description,
website, etc.  such that a Csound project becomes instantly playable
without any intervention by the end user.

Back to the CSDPlayer, I had planned to do a bit of brush up on
Android this summer, as it had been a couple years since I was last
working on mobile software fulltime at my last job.  One of the things
we may wish to look at is using ActionBarSherlock [1]  and RoboGuice
[2] (particularly the RoboGuice-Sherlock library [3] to modernize the
application.  (I'm planning on redoing my "Peaceful Breathing" Android
application using these libraries.)

Anyways, hope these thoughts are interesting and thanks again for your
work on Android!

steven

p.s. - One question I wondered, have you tried -j4 to do parallel on
your S4?  I'm very curious about parallel on mobile devices.  It's an
extremely compelling feature and I think it would differentiate Csound
from other audio solutions for mobile devices.

I imagine it's alright.  I have a Nexus One with Android 2.3.4 and I
was able to install the Gaug.es app that the RoboGuide-Sherlock page
cites as using that library. It's a little tricky to see what platform
11 maps to, but I assume it's 2.3.4.  The Android dashboard shows
platform 10 cover 2.3.3-2.3.7:

http://developer.android.com/about/dashboards/index.html

So, my best guess, considering my own device and the devices that came
out around that time, and the dashboard, I think we'd be covered.  If
you want, we could do a poll on the user's list to double check if
anyone has any particular needs for platform 10.

As for the "profiles" idea, it's not an idea I've fully mapped out.
The idea I had is that maybe CSD project could say it's using
b-format. If that's known, then the app could run Csound and manually
read the SPOUT and send that over to another Csound instance that
decodes the signal to stereo.  Other things like "accelerometer",
"compass", etc. could be other features a project might depend upon.
Then may that kind of project could run on Android or iOS, or maybe
Win8, Ubuntu Touch, Blackberry 10, etc.  Some of this is considering
edge cases; the bigger goal would really be to have works that are
dynamically generated be easier to distribute.

That's great news Michael, thanks!  I hope the app developers on iOS
and Android that consider using parallel processing will be a good
source of feedback.
