WP 10 - Android 4.4 inside

[onecosmic]

Well, after digging a little inside the new feature of running android applications on Windows 10 mobile, i've found something very, very interesting:

WP10 is running what it seems to be a reduced android 4.4 version inside.

C:\wmconnect\platform-tools>adb shell grep ro.build.version.sdk= /system/build.prop
ro.build.version.sdk=19

Sdk 19 is Android 4.4

Also it's not using dalvik, it's using ART:

[email protected]:/system/lib $ ls libar*
ls libar*
-rw-r--r-- root root 1013644 1969-12-31 21:00 libart-compiler.so
-rw-r--r-- root root 2166912 1969-12-31 21:00 libart.so
[email protected]:/system/lib $

The kernel seems to be a modified MS version, i can't find too much related but one thing is for sure, MS should release sources as it is Linux:

cat /proc/version
Linux version 3.4.0-Microsoft ([email protected]) (gcc version 4.7 (GCC) ) #1 SMP PREEMPT Wed Dec 31 14:42:53 PST 2014
[email protected]:/ $

So far i've found a couple of apk's which seems to be the ones which interfaces android with WP10:
[email protected]:/system/app $ ls mic*
ls mic*
-rw-r--r-- root root 116078 1969-12-31 21:00 microsoftappservices.apk
-rw-r--r-- root root 300688 1969-12-31 21:00 microsoftappservices.odex
-rw-r--r-- root root 53633 1969-12-31 21:00 microsoftsystemserverapp.apk
-rw-r--r-- root root 76648 1969-12-31 21:00 microsoftsystemserverapp.odex
[email protected]:/system/app $

Attached are the deodexed files for the MS applications, still working on decompiling them, way rusted with smali

Let's the game begin..


EDIT:

Another weird thing, it appears that androids runs on an hyper-v machine ?
[email protected]:/ $ ls init.hyper*
ls init.hyper*
-rwxr-x--- root shell 1725 1969-12-31 21:00 init.hyperv.rc
[email protected]:/ $

If that is true, then we are talking about another potential feature, mobile virtualization.

EDIT2:
Another interesting thing SELinux is enabled, so is not going to be easy to modify files, we need to edit the security policies...

EDIT3:
Just got an update: build: 10512
aow.wim file located at: c:\windows\system32\aow\aow.wim

there is any way to hack this feature to accept google services? and how to explore these folders that you found?

 

[Luiz Guilherme Pereira]

we need to create a swap partition, cos with ES file explorer i can only access virtual storage, yes, it is 100% virtual machined, but we need a swap partition

 

[mrchezco1995]

We should be able to Install some system apps like gapps to make Google apps work with Windows 10...

I was just wondering if we can easily access /system/ and add files there... With interop unlock we should be able to access it but who knows?

We should also have an iOS subsystem inside Windows 10 Mobile, right?

maybe yes .
did you see leaked W10 Roms for L640xl and etc. ?
they are about 2.5 GB it's a real huge ffu image and it's about 1 GB larger than 8.1 ROMs so it maybe contains much much more for example as you said maybe include an IOS subsystem
but it's really interesting to see Hyper-V mobile version working on w10 mobile !

what about root acces? If it runs on hyper-v, then I guess we have full access to android system. but what about apps that require root?
I will try to root my lumia, and install some exploits :laugh:

UPDATE:
nope...

I dumped the Android system.
Some files failed to copy because of permissions.
Here is the download link: https://mega.nz/#!h9ZQ2Q5Z!JvkrCxXYXBEDPuTctgP8Zi59PspiWn9khfV9LqzoGeI

I attached some screenshots.

So theoretically we could create a swap partition via SD card (via linux) to support the android based eco system?

No, will not include iOS subsystem.... because of copyright.

is it possible to use this to run it on a current device that still doesnt have the android system in it?
I have a Lumia 735 and it cant run the apps, infact whoever i contacted owning a Lumia 735 cannot run the system.

Nope, because it isn't a full system and a bootable hard drive (Currently Android Astoria is in a separate local disk and you need to configure 85456 things... and also need full unlock... for now).

So wanna make these android guys burn!! ?

I hope this project will be destroyed... or this will be the final autodestruction of Windows Store (mobile).

 

[augustinionut]

Why?

Nope . it doesn't make any problem to windows store in mobile and also in PC .
why ? you can't use download managers , Players and etc. why ? because they don't have access to your files
OK you can for example move your song files into the android subsystem directory to use android players . that's right . but android apps aren't able to run in background .
they are very very very limited .
project Astoria will port android apps to windows phone format apps not running them in apk format .
running apk apps only good for using some games and apps . as you can see it's a developer mode option so it's not user option .
it will help developers to check witch functions of their apps are working correctly .
hope you got what I mean .

... but android apps aren't able to run in background ...

I've tested some apps and they run in background (ex. Alarm clock plus) seems like the MS apk's that came with the Android system interfaces with WP10.

On a side note, seems like the system does not behave the same on all devices, i have a Lumia 920.

Cheers.

Yes i understood what you mean, but this tool can be used to avoid developing a new application from scratch (And there are much lazy developers in the world).

Can you guys push any apk to Android system/app folder?

 

[ADeltaX]

Can you guys push any apk to Android system/app folder?

No because the system folder is mounted as read-only.
To mount in read/write requires root....
