eclipse - 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.
