after further investigation, it seems the issue i'm having only on
framework.jar is due to the fact it now uses classes.dex and classes2.dex.

I'm not sure what you mean. The "odex" files for art are in a completely
different format. However, they do contain the original dex file, which you
should be able to extract and use as-is. As far as I know, they never contain
what was previously known as an "odex" file, so they don't need to be
"deodexed" - other than extracting the dex file.

I've of course extracted the original dex within the art file.
If it doesn't need to be deodex then i still have the above error after
disassembling and reassembling it.
Also diffin the disassembled smali code from the dex within the art file and
the disassembled one from the dex is different.
Also the first one contains many #disallowed odex opcode notes.
According to
https://android.googlesource.com/platform/dalvik/+/android-4.4.4_r1/libdex/DexOp
codes.h and
https://android.googlesource.com/platform/art/+/master/runtime/dex_instruction_l
ist.h it seems some opcodes are changed breaking compatibility with
smali/backsmali.
According to anestib https://github.com/anestisb/oatdump_plus:

That switch instruction that you posted is nonsense. It's not even close to
being a correct switch instruction. Without seeing the dex file that is causing
that, I can't theorize what the problem might be.
Regarding the "disallowed odex opcodes" - if you're seeing that the dex file
from an art ".odex" (oat) file has those, then yes, it will need to be deodexed.

Latinime dex is extracted from art, contains those disallowed odex opcodes so
should be deodexed.
It decompile without errors but many files got those packed switch errors which
prevent it to be recompile.

Aaaah, nevermind. I now see what you mean about the odex opcodes changing. I'll
need to add support for the new odex opcodes.
And that is likely to be the cause of the original switch thing too.

Just provide my solution...
The startFieldOffset changed from 8 to 0 took me a lots of time...

@riddl your solution doesn't seems to work.
I can confirm the issue is present in the final Lollipop release aswell.
wrong deodexed output sample:
#disallowed odex opcode
#iput-wide-volatile v0, v1, Landroid/system/OsConstants;->CAP_AUDIT_CONTROL:I
nop

Correct deodexed output sample:
invoke-virtual {v1}, Ldalvik/system/profiler/BinaryHprof$Tag;->ordinal()I

I've also discovered that these new files are missing the dexopt(odex) header.
No MAGIC_36, they start with dex.035 not dey.036 so baksmali fail to even
recognize them.
Original comment by pipo...@gmail.com

Yeah, that was what made me think that the oat files only contained dex files -
I didn't realize they were actually odex files, since they didn't have the dey
header.
In any case, I've started work on better support for oat files. I've currently
got some proof-of-concept code that will parse the oat file and find the dex
files that it contains. Next step will be to clean that up, add support for the
changed opcodes, and then figure out how I want baksmali to handle oat files
with multiple dex files.
I'm currently thinking changing the output structure, so that each dex file in
an oat file gets its own dir. I.e. for the boot.oat file, something like
out/core, out/framework, etc.

@pipo
It needs to set options as below
baksmaliOptions options = new baksmaliOptions();
options.apiLevel = 21;
options.allowOdex = true;
options.deodex = true;
For some classes, it will need to extract all odex from boot.oat as classPath
to resolve.
options.classPath = ...

Share the jar.
java -jar bootoat2dex.jar boot.oat
It will output to 2 folders odex and dex(de-optimized)
I have tested pack these dex to original jar and push into device,
device can boot normally.

your bootoat2dex doesn't work on released version of Lollipop (Samsung Galaxy
S5 SM-G900F). Can you update utility or publish the code?

Samsung looks have a little different format.
I have added workaround to compatible (thanks svadev@xda provide sample file).
About Samsung's topic, there is some discussion in xda galaxy s5 forum.

Just a quick update on this. The way the field offsets are calculated changed
from dalvik to art. Unfortunately, it's not looking very feasible to emulator
the exact behavior in java. The field ordering depends on a couple of
implementation-specific behaviors in the exact c++ library being used. In
particular, the exact implementation of std::sort, which is non-stable.. so the
order of equal items is unspecified, and similarly, the exact implementation of
priority_queue, which also does not guarantee the order of equal items.
So, I'm thinking it's going to be infeasible to update baksmali to be able to
handle art odexes for now. Doing so would likely require some sort of on-device
helper program to get the field offsets, similar to the original "deodexerant",
and I'm not really interested in going that route.

There were some recent changes to art that make the field offsets more
well-defined, and I do plan on adding support for deodexing odex files created
by versions of art after these changes went in. However, note that there is no
released build of Android that has all of those changes yet.

Deodexing art odexes is not supported and does not work. There were some recent
changes in art which will make it possible. I will add support in baksmali for
deodexing odex files created by newer versions of art with these changes. But
the changes aren't in any released version of Android yet.
The switch thing is likely just a symptom of some of the optimized opcodes
changing between dalvik and art. That is simple enough to fix, but there are
other problems with deodexing that I've mentioned previously.

@jesusfreke
Thanks you very much, i'm glad to ear art odex will get supported for future
android releases.
I'm not a programmer and not sure if this is related to the fields offsets
problem you mentioned earlier but you may want to consider that riddl solution
is working good on current art odex and he changed the startFieldOffset from 8
to 0 and is not using any on-device helper program.

You mean this: https://github.com/JesusFreke/smali/pull/30? That may work for
specific cases, but it isn't guaranteed to work in general.
