 * MyParcelable happy = new MyParcelable();
 * byte[] toByte = ParcelableUtil.marshall(happy);
 * // Save to DB? Send via socket?
 * // ...
 * // Restore from DB?
 * byte[] fromByte = cursor.getBlob(c);
 * MyParcelable happy = ParcelableUtil.unmarshall(fromByte, MyParcelable.CREATOR);

Thank you for posting this, really appreciate it! This allowed me to send a parcelable object via a bluetooth socket connection.

Thank you.. it really helps me !! ^^;
GOD bless you.!!

I didn't know about the parcel.setDataPosition(0);
thank you...
