Android SW Development - Porting MPD to Android - Android Q&A, Help & Troubleshooting

Hello, I am looking to port MPD, the music player daemon SERVER to the Android platform. I was wondering if anyone had any advice to this end?
So far I imagine it will involve getting the sources of MPD (can't do that at work so will check tonight), finding an Android compiler and building all the dependencies and MPD itself using that? I believe the Android NDK can compile C and C++ into .apk's which then run in an Android virtual machine, but I'm not sure what issues that might cause on MPD in terms of accessing the audio hardware etc..
Failing this, perhaps an alternative is to install Linux for Android and run MPD directly out of that? I want to stick my phone straight into a speaker and use it to play music from a Windows or Linux machine on my LAN - this is exactly what MPD enables so I would really like to see a server port for Android, as would many others from what I've seen in my searching for it.
PS I know this is a sw development question but apparently I don't have enough posts to ask this question in the appropriate place.

I think this deserves a bump. Also a moderator needs to move it to the correct forum since I had too few posts to post it to the correct one.

I have considerable interest in getting MPD to run on Android as well. Now that XBMC is running on Android and the Nexus Q exists, it seems I have found an acceptable HTPC frontend.
I myself have not yet used XBMC for my music though, perhaps it is sufficient and mpd is not needed?
In terms of getting MPD to run in Android, we can drop the need for FFmpeg by using mediaplayer: developer.android.com/guide/topics/media/mediaplayer.html

---

What about a raspberry pi and raspbmc, regarding your wish for an HTPC? Believe this is much cheaper than using an Android based device.
Thanks for referencing me to that API... perhaps the ideal way to proceed is to develop a basic Android app using that and a basic JSON-RPC interface to be able to control it from any other device.

is there any progress in this regard? i'd love to install an mpd server, when i get my ouya

Checkout github.com/rumpeltux/mpd/tree/android. It compiles and runs fine for me.

It didn't work for me..
How did you achieve it?

I cant compile it, too.
A good Readme with depencies would be great.

I used a current Ubuntu. You may need: git build-essentials realpath autoconf automake libc6-dev-i386, not sure if more.
You’ll also need the android SDK and NDK (I used version r8e).
Code:
# clone the repository
cd mpd
git checkout android
# Be sure to adjust the paths in the top of compile-android.sh according to your sdk & ndk-location
./autogen.sh # Will start compiling, but it's ok if it fails.
./compile-android.sh

still not working
Thank you, but its is still not working.
I have sdk and ndk (same version) and adjusted the paths.
./autogen.sh #no errors
./compile-android.sh
ive tried to install the libs (configure: WARNING: ...) and reduced the warnings, but these libs i cant find.
problem is now:
Code:
In file included from src/PcmConvert.hxx:27:0,
from src/PcmConvert.cxx:21:
src/pcm_resample.h:31:24: fatal error: samplerate.h: No such file or directory
compilation terminated.

mpd seems to be using the host system to detect which libraries are available. You’ll either need to uninstall those (in your case libsamplerate0-dev I guess) or adjust the configure command for mpd in compile-android.sh with a flag to explicitly disable the library (like --disable-lsr I guess).
My configuration looks like this (if you have more things in there, you most likely need to disable these explicitly):

I got error
Code:
./compile-android.sh: 8: ./compile-android.sh: realpath: not found

But is it truly impossible to use direct alsa output here? Running this as root could possibly solve some problems...
