EthereumAbi.encode not working properly

[MhAhmadAli]

Describe the bug
I am using EthereumAbiFunction for erc20 transfer function. I have an empty project with just the HD Wallet and this function related code.

When I use EthereumAbi.encode(transferFn).toHexString(), it returns the following:
0xa5f7c148000000000000000000000000a90aeb820925694c0c1b23a63bb9cb55f38525200000000000000000000000000000000000000000000000000000000005f5e100
This doesn't look good. The output should start with 0xa9059cbb instead of 0xa5f7c148. This was working fine previously but suddenly it decided to change itself.

This was a part of a bigger project and I was having this issue so I tested this in an empty project as well.

The version I am on is 3.2.5.

One more thing I would like to point out is when using the latest version 4.0.4, I don't get any output from the encode function at all.

Hi @MhAhmadAli, I checked the example you sent me, and the values at screenshot doesn't match the result you've sent.
First of all, the 0xa5f7c148 prefix can be if the function has the following type: transfer(address, int). But if the function type is transfer(address, uint), the prefix will be 0xa9059cbb as you expect.
Secondly, the amount on the screenshot should be 100000000 to get 0x05f5e100, but it's 1000 times less.

Please make sure if you use the API in a correct way. We have multiple examples in Kotlin here: link

Last, consider using the new API: link

Hi @satoshiotomakan, Thanks for the info on the new API. I looked through the docs after the update but there was no mention of this at that time so I didn't update my version.

I will test it and let you know.

Fixed the issues for me. Thanks for the help.
