Hi,
I see, like described in v0.41.0, some dependecies updates. Something leads to the android compatibility issues with relative old versions (e.g. try do following on API less than 28 (Android 9)):
AccountConverter.enableMuxed().encode("account")
java.lang.NoSuchMethodError: No static method isEmpty([B)Z in class Lorg/apache/commons/codec/binary/BinaryCodec; or its super classes (declaration of 'org.apache.commons.codec.binary.BinaryCodec' appears in /system/framework/org.apache.http.legacy.boot.jar)
at org.apache.commons.codec.binary.BaseNCodec.decode(BaseNCodec.java:407)
at org.apache.commons.codec.binary.BaseNCodec.decode(BaseNCodec.java:451)
at org.stellar.sdk.StrKey.decodeVersionByte(StrKey.java:142)

What did you expect to see?

It cannot run successfully below Android API 28.

What did you see instead?

It run successfully below Android API 28.

The Android framework includes a low version of commons-codec, which does not include the Base32 module, while our library uses the Base32 module. See https://stackoverflow.com/a/29833101

Possible solutions

• Remove commons-codec from SDK dependencies list
• Provide shadow jar
