I'm trying to convert an android.graphics.Path object to byte[] so that I could store it in a blob storage in SQLite, also to convert it back.
So far I don't even know where to begin...
Thanks to anyone willing to help.

As Path extends Object, you can use something like this:
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
ObjectOutputStream objectOutputStream = new ObjectOutputStream(outputStream);
objectOutputStream.writeObject(path);
byte[] array = outputStream.toByteArray();

Since Path is not serializable, trying this will throw a java.io.NotSerializableException: android.graphics.Path

@jhnewkirk You can make a serialized class Path by overriding the methods before the C native methods calls.
Serialize your object and upload that file .
ByteArrayOutputStream baos = new ByteArrayOutputStream()
ObjectOutput out = new ObjectOutputStream(baos);
out.writeObject(android.graphics.Path);
out.close()
byte[] buf = bos.toByteArray(); //byte array
to recover that object use deserialization
ObjectInputStream in = new ObjectInputStream(new ByteArrayInputStream(buf));
class_name recover =(clas_name) in.readObject();
in.close();
return object;
