ANDROID Operating Systems on BeagleBoard. In ANDROID there is no

 Which port does the converter show up on?  Typically something like /
dev/ttyUSB0.  Then put something like this in the init.rc

service ril-daemon /system/bin/rild -l /system/lib/
-- -d {your serial port}
    socket rild stream 660 root radio
    socket rild-debug stream 660 radio system
    user root
    group radio cache inet misc

In my case, {your serial port} was /dev/ttyUSB1.

1. Using SoundPool.load(FileDescriptor, ... ) to load a sound file

I tried using the load function of the SoundPool that takes a
FileDescriptor, because I want to set the offset and length of the
file to be played. The File is not stored in the Ressources but a file
on the storage card. Even though neither the load nor the play
function of the SoundPool throw any Exception or print anything to the
console, the sound is not played. Using the same code, but use the
file path string in the SoundPool.load() function works perfectly.

This is how I have tried the loading (start equals 0 and length is the
length of the file in miliseconds):

FileInputStream fileIS = new FileInputStream(new File(mFile));
mStreamID = mSoundPool.load(fileIS.getFD(), start, length, 0);
mPlayingStreamID =, 1f, 1f, 1, 0, 1f);

If I would use this, it works:

mStreamID = mSoundPool.load(mFile, 0);
mPlayingStreamID =, 1f, 1f, 1, 0, 1f);

Please help... Thanks
