Base64 decoder in android at API level 7

Question

How to decode a base64 encoded string into a byte array at the Android 7 API level?

Can this be done using standard Java packages?

Should I copy the source code from Google search results?

Should I reuse the encoder and decoder in accordance with the RFC?

PS: Level 8 API uses the android.util.Base64 package that does this, but I need to do development based on API level 7.

Answer 1

You can use this class,

org.bouncycastle.util.encoders.Base64

BouncyCastle is included in level 7.
