base64 decoder in android in API level 7

Question

How to decode a base64 encoded string to byte array on Android API level 7?

Can it be done using any standard packages of Java?

Should i copy the source code from google search results?

Should i re-implement encoder and decoder according to RFC?

PS: API level 8 has util package android.util.Base64 that does this, but i have to do development based on API level 7.

or do as suggested in the answer to http://stackoverflow.com/q/4322182/808940 — Moog, Oct 08 '11 at 12:55

Not sure if there's n or not, but if there isn't, I wouldn't implement your own, I'd use something like Mikael Grev's MiGBase64 which has been extensively tested and (as far as I can see) should work on Android

It was added in v8 (android 2.2). See android.util.Base64

I had to use Base64.NO_WRAP on Android to make it match plain Java results

Plain Java==>DatatypeConverter.printBase64Binary( string2Encode.getBytes() );
Android==> Base64.encodeToString( string2Encode.getBytes(), Base64.NO_WRAP );

You can use this class,

org.bouncycastle.util.encoders.Base64

BouncyCastle is included in Level 7.

I couldn't find the BouncyCastle in the android.jar packages list at http://developer.android.com/reference/packages.html. – Suresh Jun 30 '10 at 08:27
You are right. It wasn't there. We include a BC jar and I thought it came with Android. – ZZ Coder Jun 30 '10 at 11:55
This answer is still useful for those who have already been using BouncyCastle for other purposes. – Muntashir Akon Dec 09 '21 at 18:07
