Hi,

Reading the bold text I suspect you are not using a valid zip file? But again, this library is not made by us nor have we worked with it, so I am not able to say anything specific, unfortunately.

[DfuArchiveInputStream] -keep class no.nordicsemi.android.dfu.** { *; }
[DfuArchiveInputStream] to your proguard rules?

Hi,

The Laerdal.Dfu is a third party library that we have no experience with, so we are unfortunately not ablet to support this directly. Perhaps someone from the community has some input? (That said, the errors seem like generic Android errors, so I expect you should be able to debug it if you are used to working with Android).
