How to convert Map to Bytes and save to internal storage

How can I convert my Map> to byte[], and then write it to internal storage? I currently have:

I know I am subscribing to an old thread but it popped out in my google search. So I will leave my 5 cents here:

You can use org.apache.commons.lang3.SerializationUtils which has these two methods:

/**
 * Serialize the given object to a byte array.
 * @param object the object to serialize
 * @return an array of bytes representing the object in a portable fashion
 */
public static byte[] serialize(Object object);

/**
 * Deserialize the byte array into an object.
 * @param bytes a serialized object
 * @return the result of deserializing the bytes
 */
public static Object deserialize(byte[] bytes);
