NoSuchMethodError using commonc codec in Android application

Question

I added the commons codec from apache.org (commons-codec-1.4.jar) in eclipse for my Android application following the instruction here. There is no error in the code. But when I run the application and call the function that use the codec the application stop and need a fore close.

In the logCat says:

Android Runtime: java.lang.NoSuchMethodError: org.apache.commons.codec.binary.Base64.encodeBase64String

the codeline is: String tmpStr = Base64.encodeBase64String(msg); //msg is a byte[]

The application is for a min SDK version = 7 (Android 2.1), so I can't use Android Base64

Any idea how can I solve the problem?

Answer 1

I couldn't get the commons codec to run on a 2.1 emulator either. I gave up in the end and made my own, copying the code from:

Base64 encoder/decoder

It's only just over a hundred lines or so.

Answer 2

I experienced the exact same problem. So i started browsing the android source code, and as it turns out Don's guess about Android having an implementation of org.apache.commons.code.binary is correct. he's wrong about the ability to access it, you can, but its version 1.2 of the apache commons, not version 1.4 or even 1.5. You can see for your self in the android source.

Also as a note, this question is a duplicate of this post.
