Looking my projects     https   github com master255 ImmortalPlayer http FTP support  One thread to read  send and save to cache data  Most simplest way and most fastest work  Complex logic - best way  https   github com master255 VideoViewCache Simple Videoview with cache  Two threads for play and save data  Bad logic  but if you need then use this

Android MediaPlayer doesn t support streaming of MP3 natively until 2 2  In older versions of the OS it appears to only stream 3GP natively  You can try the pocketjourney code  although it s old  there s a new version here  and I had trouble making it sticky     it would stutter whenever it refilled the buffer    The NPR News app for Android is open source and uses a local proxy server to handle MP3 streaming in versions of the OS before 2 2  You can see the relevant code in lines 199-216  r94  here  http   code google com p npr-android-app source browse Npr src org npr android news PlaybackService java r 7cf2352b5c3c0fbcdc18a5a8c67d836577e7e8e3  And this is the StreamProxy class  http   code google com p npr-android-app source browse Npr src org npr android news StreamProxy java r e4984187f45c39a54ea6c88f71197762dbe10e72  The NPR app is also still getting the  error  -38  0   sometimes while streaming  This may be a threading issue or a network change issue  Check the issue tracker for updates

I ve had the same error as you have and it turned out that there was nothing wrong with the code  The problem was that the webserver was sending the wrong Content-Type header   Try wireshark or something similar to see what content-type the webserver is sending
