I have an application that will record and play audio files. Some of the audio files are downloaded using simple standard http downloads using httpclient. It worked like a charm for a long time. Now all of a sudden I cannot play the files I download. It fails with this stack. I store the files on the SDCard and I experience the problem both on a handset and a USB connected device.

I have checked that the downloaded file is cool on the server, and I can play it without any issues.

These are the code snippets I use ( I know that recordingFile is a valid path for the file).

    // inside the activity class
    private void playRecording() throws IOException{
        File recordingFile = new File(recordingFileName);
        FileInputStream recordingInputStream = new FileInputStream(recordingFile); 
        audioMediaPlayer.playAudio(recordingInputStream);
    }

Here is the media player code:

    // inside my media player class which handles the recordings
    public void playAudio(FileInputStream audioInputStream) throws IOException {
        mediaPlayer.reset();
        mediaPlayer.setDataSource(audioInputStream.getFD());
        mediaPlayer.prepare();
        mediaPlayer.start();
}

Here is the exception:

E/MediaPlayerService(  555): offset error
E/MediaPlayer(  786): Unable to to create media player
W/System.err(  786): java.io.IOException: setDataSourceFD failed.: status=0x80000000

W/System.err(  786):    at net.xxx.xxx.Downloads$1.onClick(Downloads.java:135)

I have tried seeking some answer of the offset error, but not really clear what this issue might be.

PS I download the file with this code:

    public FileOutputStream executeHttpGet(FileOutputStream fileOutputStream) throws ClientProtocolException, IOException{
        try {     
            // Execute HTTP Post Request  
            httpResponse = httpClient.execute(httpPost, localContext);
            int status = httpResponse.getStatusLine().getStatusCode();

            // we assume that the response body contains the error message
            if (status != HttpStatus.SC_OK) {
                ByteArrayOutputStream ostream = new ByteArrayOutputStream();
                httpResponse.getEntity().writeTo(ostream);
                fileOutputStream = null;
            } else {
                InputStream content = httpResponse.getEntity().getContent();

                byte[] buffer = new byte[1024];
                int len = 0;
                while ( (len = content.read(buffer)) > 0 ) {
                    fileOutputStream.write(buffer,0, len);
                }
                fileOutputStream.close();
                content.close(); // this will also close the connection
            }

        } catch (ClientProtocolException e1) {  
            // TODO Auto-generated catch block 
            e1.printStackTrace();
            fileOutputStream = null;
        } catch (IOException e2) {  
            // TODO Auto-generated catch block  
            e2.printStackTrace();
            fileOutputStream = null;
        }
        return fileOutputStream;
    }
