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

  • 0

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.

    You can use this class,

    org.bouncycastle.util.encoders.Base64
    

    BouncyCastle is included in Level 7.
