java.awt.Toolkit.createImage replacement in Android

I am trying to convert my Java Applet which connects to a video surveillance server to run on Android. I am having issues with trying to convert a byte array containing a JPEG image to a Bitmap object on Android.

The Applet code is:

private Toolkit Tk = Toolkit.getDefaultToolkit();
private Image m_Image = null;

byte[] buf = this.SockClient.ReadStream(size));
m_Image = tk.createImage(buf);

My Android code is:

private Bitmap m_Image = null;
ByteBuffer bb = null;

m_Image = Bitmap.createBitmap(320,240,Bitmap.Config.RGB_565);

byte[] buf = this.SockClient.ReadStream(size);
bb = ByteBuffer.wrap(buf);
m_Image.copyPixelsFromBuffer(bb);

I am getting a NullPointerException after calling copyPixelsFromBuffer.

I'm guessing I am using the wrong methods to do the job.

Use BitmapFactory and decodeByteArray() to convert a byte[] of JPEG data to a Bitmap.
