public class Base64Utils
extends java.lang.Object

Utility class for Base64 encoding. Froyo and newer versions of Android include Base64 support. If the environment is determined to be Froyo or later, then this class delegates to Base64. If the version is older than Froyo, then Robert Harder's public domain Base64 class is used.

Method Detail

encode

public static byte[] encode(byte[] input)

Base64 encodes the input. If the version of Android is Froyo or newer, then this method delegates to Base64.encode(byte[], int). Otherwise Base64.encodeBytesToBytes(byte[]) is used.

Parameters:

input - the byte array to encode

Returns:

encoded byte array

encodeToString

public static java.lang.String encodeToString(byte[] input)

Base64 encodes the input. If the version of Android is Froyo or newer, then this method delegates to Base64.encodeToString(byte[], int). Otherwise Base64.encodeBytes(byte[]) is used.

Parameters:

input - the byte array to encode

Returns:

encoded String

decode

public static byte[] decode(byte[] input)

Base64 decodes the input. If the version of Android is Froyo or newer, then this method delegates to Base64.decode(byte[], int). Otherwise Base64.decode(byte[]) is used.

Parameters:

input - the byte array to decode

Returns:

decoded byte array

decode

public static byte[] decode(java.lang.String str)

Base64 decodes the input. If the version of Android is Froyo or newer, then this method delegates to Base64.decode(String, int). Otherwise Base64.decode(String) is used.

Parameters:

str - the String the decode

Returns:

decoded byte array
