将byte []解码为string [] []

Question

I am storing a string[][]-array into a database as a "blob". Loading the data, I initially get a byte[]-array, which I then need to decode to string[][] again.

So: Can anywone tell me if there is a way to convert a byte[]-array to a string[][]-array (on Android)? Or if there is a way to convert a byte[]-array to an ArrayList ?

I asked a similar question once, but the question was referring to blobs.

Answer 1

You would normally convert a byte array to a single blob - why would you want an array of blobs? Would you want a single blob per byte? That sounds unlikely.

Creating a single blob for an array of bytes is easy though... for example, with a PreparedStatement :

statement.setBlob(parameterIndex, bytes);
