Does this solve the issue ?

I have encountered the same crash using version 1.16 running on Android 4.4.2, although it worked correctly on a device running 5.0. Recompiling from the 1.16 tag using the android profile made no difference.

However, I checked out the 1.15 tag and compiled that (using the android profile) and that worked on both Android 4.4.2 and 5.0.

I am not really sure what's going on. I guess Message.class is the android.os.Messag, am I right?

I have tried simple dump/load of the empty new Message() with version 16 and 17-SNAPSHOT built with -Pandroid. It worked find (at least without exceptions) in Emulator with API_19_4_4 and API_22_5_0 and on real OnePlus 2 running OxigenOS 2.2.0 which is 5.1.1

I thing we need to figure out why it is java.lang.VerifyError

JavaDoc for VeifyError.class says :

Thrown when the "verifier" detects that a class file, though well formed, contains some sort of internal inconsistency or security problem.

In mine experience it could be anything :) Unfortunately not so much of android development I know.

Could it be connected to something like Android java.lang.VerifyError ?

This jar file worked. http://www.java2s.com/Code/Jar/s/Downloadsnakeyaml110androidjar.htm

I think the library is missing some Android stuff such as Manifest info.

[Alexander Maslov]

As you can see from that jar you pointed out - it's MANIFEST.INF is empty, so is the one in snakeyaml-...-adroind.jar which you can build yourself. So check your App project where you use SnakeYAML-android jar and see what could be wrong there, because at the moment I do not see SnakeYAML as the main reason of this problem.
