​Android Base 64 encode and decode example code

First:

• Choose an encoding (UTF-8 is generally a good choice)

Transmitting end:

• Encode the string to bytes (e.g. text.getBytes(encodingName))

• Encode the bytes to base64 using the Base64 class

• Transmit the base64

Receiving end:

• Receive the base64

• Decode the base64 to bytes using the Base64 class

• Decode the bytes to a string (e.g. new String(bytes, encodingName))

EDIT: So something like:

// Sending 

sidebyte[] data = text.getBytes("UTF-8");

String base64 = Base64.encodeToString(data, Base64.DEFAULT);

// Receiving 

sidebyte[] data = Base64.decode(base64, Base64.DEFAULT);

String text = new String(data, "UTF-8");
