An Android Logging Class That Writes to SD Card

In case anyone's interested... I'm currently trying to work out the cause of a very uncommon lockup that happens with one or two of the wallpapers.  It only seems to happen on HTC phones so I'm honestly guessing it's a driver bug, but the real problem is that it happens with no apparent cause with a frequency of perhaps once or twice per day.

I've got an HTC Incredible here that I have seen it happen on, the problem is actually seeing what's going on.  I'd normally use the system log, but since this problem can lock-up the phone, that log gets wiped out upon a restart.  So, I've tossed together a simple static logging class that can output to an SD card.  The filename is tagged with the date and time upon creation, so it won't overwrite an earlier file, and since it's on the SD card it can run and get plenty gigantic.  I've put calls to LogToSD.write at the top of basically every single method on the wallpaper, so it's going to get big by the time I see it lock up next.  :P

Here's the class, if anyone's looking for something like this.  Don't forget you'll need to set uses-permission WRITE_EXTERNAL_STORAGE.

public class LogToSD
{
    static PrintWriter outFile = null;
  
    private static void initialize()
    {
        try {
            File root = Environment.getExternalStorageDirectory();
            if( root.canWrite() )
            {
                Calendar rightNow = Calendar.getInstance();
                long day = rightNow.get( Calendar.DAY_OF_YEAR );
                long hour = rightNow.get( Calendar.HOUR_OF_DAY );
                long minutes = rightNow.get( Calendar.MINUTE );
                long seconds = rightNow.get( Calendar.SECOND );
              
                String date = day + "-" + hour + "-" + minutes + "-" + seconds;
              
                File gpxfile = new File( root, "log_" + date + ".log" );
                FileWriter gpxwriter = new FileWriter( gpxfile );
                outFile = new PrintWriter( gpxwriter );
                outFile.write( "\n\n----- Initiating LogToSD Session -----\n" );
                outFile.write( "----- Start Time: " + date + " -----\n\n" );
            }
        } catch (IOException e) {
            Log.e( "LogToSD", "Could not write to file: " + e.getMessage());
        }
    }
  
    public static void write( String text1, String text2 )
    {
        if( outFile == null )
            initialize();
      
        Calendar rightNow = Calendar.getInstance();
        long minutes = rightNow.get( Calendar.MINUTE );
        long seconds = rightNow.get( Calendar.SECOND );
        long ms = rightNow.get( Calendar.MILLISECOND );
      
        String time = minutes + ":" + seconds + "." + ms;

        outFile.write( time + "\t" + text1 + " " + text2 + "\n" );
        outFile.flush();
      
        Log.v( "LogToSD", text1 + " " + text2 );
    }
  
    public static void shutdown()
    {
        if( outFile != null )
            outFile.close();
    }
}
