I am working in Android. I need to convert byte[] to Buffer type. In Android, I have seen a type Buffered that I needed to use in particular functions. But, I my data source is type byte[].

The ArrayBuffer object is used to represent a generic, fixed-length raw binary data buffer. It is an array of bytes, often referred to in other languages as a "byte array".
There are two ways to convert byte array to String: By using String class constructor. By using UTF-8 encoding.
A ByteBuffer is a buffer which provides for transferring bytes from a source to a destination. In addition to storage like a buffer array, it also provides abstractions such as current position, limit, capacity, etc. A FileChannel is used for transferring data to and from a file to a ByteBuffer.
Convert byte[] array to File using Java In order to convert a byte array to a file, we will be using a method named the getBytes() method of String class. Implementation: Convert a String into a byte array and write it in a file.
Take a look at ByteBuffer.wrap:
byte[] bytes = ...;
Buffer buf = ByteBuffer.wrap(bytes);
There's also a ByteBuffer.wrap(byte[] array, int start, int byteCount) if you only want to wrap part of an array.
