This kind of question seems more like a school homework assignment, but in case the question is practical, here goes.
What Base64 is: http://en.wikipedia.org/wiki/Base64 This article gives plenty of examples and details that someone can write their own fully-tested implementation in an hour. But in twenty seconds of using Google, I tried the search string of "base64 encode in java" and got tons of hits. The third link has a fully-tested implementation (based on the same Wikipedia example data and algorithms). http://www.wikihow.com/Encode-a-String-to-Base64-With-Java Now, it's not good form to just copy code without asking, but since this is a How-To article published on the web, I don't think you'll run into copyright issues if you adapt their code into your application. There's good discussion in the article about how the code works, and advice on learning to program. However, this question is even sillier than that. The Android platform even includes a class called Base64 which does all the encoding and decoding for you. Without worrying about incompatibility, testing, or license issues! http://developer.android.com/reference/android/util/Base64.html That class even has an .encodeToString() method that turns your arbitrary byte[] data into a String ready for use in sqlite TEXT fields. Beyond that, I'm really not sure what the actual problem is. I'm not trying to be rude, but it's depressing when people ask questions that are so quickly answered with even the most cursory search first.
