Steps to Reproduce

1. apktool d Home.apk

Frameworks

If this APK is from an OEM ROM (Samsung, HTC, LG). Please attach framework files
(.apks that live in /system/framework or /system/priv-app)
Android Beta m3 framework-res.apk(doesn't changed anything to M5)

APK

If this APK can be freely shared, please upload/attach a link to it.
Home.apk

Questions to ask before submission

1. Have you tried apktool d, apktool b without changing anything? - No, because it can´t decompile
2. If you are trying to install a modified apk, did you resign it? - I don´t can install it, because i can´t decompile it.
3. Are you using the latest apktool version? - Yes

Yeah doesn't work on latest. I'll take a look when I'm back in the zone of disassembly errors and take another look.

Thanks

The same with all Apks from Android Beta m5-rc-14. All available at https://github.com/user0-tb/ApktoolDebug

Is it fixable?

[iBotPeaches]

Sorry I don't tend to like mixing working on issues recently. I've found it more helpful for me to stay focused on an a single issue on the way towards resolution. Once I'm complete with my latest ticket (#2836) - I'll revisit open tickets.

So I don't have an answer yet.

[user0-07161]

If you need any Files or Source Code, ask me, before closing issue, because I have some Source Code of Android Beta M5 and M3.

[iBotPeaches]

I took a look - this is because we either regressed or the packing order of chunks was different back then.

F: Chunk #1 start: type=0x0002 chunkSize=0x0002c8fc
F: Chunk #2 start: type=0x0001 chunkSize=0x00010f84
F: Chunk #3 start: type=0x0200 chunkSize=0x0001b96c
F: Chunk #4 start: type=0x0201 chunkSize=0x00003b80

What I tend to normally expect

F: Chunk #1 start: type=0x0002 chunkSize=0x0010ca40
F: Chunk #2 start: type=0x0001 chunkSize=0x0007132c
F: Chunk #3 start: type=0x0200 chunkSize=0x0009b708
F: Chunk #4 start: type=0x0202 chunkSize=0x00000060

We are basically reading types without specs so lots of NPEs on that path. Probably fixable if we change up our type loading to be more deferred.

[iBotPeaches]

This looks to be a never ending journey of patches. I'm going to toss in backlog @user0-tb.

If you have source of the framework-res or ResourceTypes.h - I can revisit.

[user0-07161]

Here @iBotPeaches
Framework-res:
framework-res_src.zip

[iBotPeaches]

@user0-tb - This doesn't look like the source of the application, just the source (java) portion.

[iBotPeaches]

I've decided after peeking a bit more - that there is real no chance of this older M builds working on compilation. The build tools of this era will generate a resource table that Milestone builds from '08 have zero chance of understanding.

So I'll merge a PR that at least fixes disassembly, but not going to have any chance of compilation. This seems like a happy medium for how old this is.

Ticket will close on merge of PR.

[user0-07161]

It´s working now! Thanks @iBotPeaches!
