Does anyone know of any VirtualBox Android Emulator that has Marketplace?
Thanks!
Oh, I forgot to add "that's free" and not the $50 that some cheeky bastards are trying to charge for a thing called AndroidVM!

Android doesn't just load up and run on a PC. It's a source code project that a real developer has to spend time porting from platform to platform, unless you want to run it from a runtime built from the SDK. To do that requires an underlying OS, like Windows, Linux a MAC - something capable of running the SDK.
Since, VMware is emulating a PC, then in order to run as a real virtual machine, android needs to be pretty much ported to a PC. Since Android is built on a Linux kernel, it's not impossible, but geese - why? That said, it's bound to show up on an Intel compatible tablet at some point, if it hasn't already.

I'm already running Android under Virtualbox - I just wondered if there's a version for VB that has Marketplace.

Wow. So much complete and utter wrong in one post... I've been running Android under a virtual machine for quite a while...
There is an x86 version of Android available at androidx86.org
It will definitely run under Virtual Box or any other virtualization software package. It's Android 1.6 by the way, and you will have to perform some geek-like activities to simulate an SD-card to install appz.
Big question is whether an ARM-device version of Android would work in a normal VM emulator (not talking about Bochs and stuff).

Well, since I hadn't heard of a port to x86, I was certainly wrong about that, which makes the rest of the post moot, but not wrong. In any event, I stand corrected.
sorry to add a flame of any kind but this

is totally wrong.
Virtual machines virtualise the hardware of your machine (bad explanation I KNOW). if you have a PowerPC you can only emulate PowerPC (Mac for those that dont know) and intel/amd chips are things like x86 then theres smaller devices like ARM. my point is that if you have a Intel/amd box you can only emulate x86 O/S. however if you have a netbook with a version of linux or windows built on arm arch then u could prob get away with the original android if you are running normal x86 then u require android that has been built from source on x86.
this made me laugh
"Since Android is built on a Linux kernel, it's not impossible"
all i can say is what??
anyway back to the point... to run android on a x86 box u need x86 android
The problem with getting the Market to work is simply that the GApps are currently only available in a compiled for ARM version. period. that's the answer you wanted to hear i guess.

VMware and Virtualbox emulate PC hardware. Since Android runs on a Linux kernel, and Linux was originally developed for an x86 PC, it follows that a port of Android could be done for a PC. Since this was not a generic discussion about virtual machines but a specific discussion about PC emulation, I don't see where the argument is.
PC = x86 and it's successors. You said I was totally wrong and then pretty much made my case. The only point I missed is that the work had already been done. To run Android in a x86 (PC) VM, you'll need an X86 (PC) compatible version of Android - right - what I said.
Right... Ok, now does anyone know the answer to the original question?

They state they are running Ubuntu in a VM, then installed the Android emulator in Ubuntu, then the android emulator is setup to have the Marketplace. The android emulator is doing the ARM emulation.
I think using qemu User Mode emulation it might be possible to actually launch the Marketplace and apps via android-x86 without using a phone emulator. Not sure it would be that valuable, but it would allow lots more apps on a netbook running Android.

I imagine it would be a mess to get a touch screen working in android running on an emulator.
I read reviews on androidx86 booted (not emulated) on a few netbooks that ran great and very responsive..I also read one on a touch screen comp that worked fine..they claim all apps work-minus gapps obviously.
I plan on trying this on my Toshiba nb205 netbook today and can post a review if anyone is interested..

A review would sure be appreciated. More knowledge is always better.
Just a quick follow up, I tried out the Androidx86 on my netbook this weekend, both booted off the usb and installed on the hd..it runs..nothing spectacular and slightly dissappointing. You still only have a 4x4 screen and the Marketplace is entirely different, very small selection of "blah" apps..none of my favorite android apps anyways-facebook,twitter,gmail..not really any widgets either. Lastly, you need to use an external mouse..the touchpad just moves the background but gives you no pointer (could be a hardware compatability issue tho)..
On the positive side, the internet was very fast and resume time was almost instantanious..not really any major bugs, just nothing too special..
This method works with 1.6 as originally described here:
link-> forum.xda-developers.com/showthread.php?t=529170
I got it to run with the signed-dream_devphone_userdebug-img-14721.zip image from HTC for the developer phone.
link-> developer.htc.com/adp.html
I replaced the android-sdk-windows\add-ons\google_apis-4_r02\images\system.img with the one from the signed-dream_devphone_userdebug-img-14721.zip
(you should backup the original system.ini)
I then used the Android SDK GUI interface to create a Google API Level 4 machine.
I did not need to install the marketenabler.apk, as described in the original thread.
It boots up like a new Dev Phone, it behaves like there is a valid SIM and working data connection.
CTRL-F11 rotates the screen (slide out keyboard).
I have only installed a few free apps (K9 mail) but they seem to work fine.
I can't post links so copy, and paste them.
It would be trivial to create an Ubuntu virtual machine and then install the Android SDK inside of it and modify the system.img. Installing the SDK on your own machine probably takes less space and resources then running it inside another VM.

Updated, not corrected.
Yes, you were absolutely correct except for being out of date, because that process you described has already taken place as others have now pointed out.
To the person who said he was wrong, actually, no.
Android as it stands on the phone, is an ARM system compiled in ARM machine code. Android apps are hardware/platform agnostic but the operating system is not, it does have to be ported and recompiled for any different hardware system. That being said, it seems that most of that work is finished, ala androidx86.org

x86 Android Market
I have been reading a bit. It seems that it is possible to have Gapps installed for x86.
Froyo, people have been using Cyanogen 6 Gapps for Tegra.
Android x86 launched their Gingerbread version not long ago. It would not surprise me if Cyanogen 7 Gapps worked with it. Different devices used different versions and now there is just one version for all. It should be possible to run VM from the desktop.
NDK dependent Apps: in theory, it may be possible taking the apk using android apk tool, x86 NDK from the x86 build and rebuild it for x86 code.
I will be playing with an old EEE900 and see how this goes sooon.

Ya it is much easier to run ubuntu or debian do to the fact that android is already a linux distribution, and ubuntu and debian both support arm processors standard which is what android phones use. Also in order to emulate windows you would have to emulate the intel cpu and that would make things unbairably slow, to the point of being almost unfunctionable.
Hope that helps

Wine is not an emulator, it only translates some platform-dependent things so windows app can run on Linux. As a result wine can only run on x86 architecture. To run windows on ARM android there are many x86 emulator available but of course the performance is not very satisfying. Windows 98 or below can run although with a bit slow. windows XP and later is much heavier so you can't run it in an emulator with acceptable speed
Linux have distros for ARM so it's much easier to install
with devices like s4 and xz is it still too hard to run win 7 in an emulator? win 8 has arm support

Windows Emulator
Hi I'm farely new to xda (over on the Rezound forums mostly). Just recently I've been looking into tablets since my laptop died. My friend has this tablet and from what I've seen and read it's a good buy. Since im replacing my laptop with this I'd need to be able to run exe files. Is it possible to root and mod this to be able to run exe files? Or not since this a an android device? Sorry if this is a basic question again I'm new here. Thanks for help in advance
hmmmm, i dont think thats possible. Unless you install a different OS on it. But with pure android OS, i dont think so. EXE is kind of windows specific. But, what app are you trying to install using an EXE file? Im pretty sure there is an android equivelant for the app.
May have problems with it as exe is a program compiled for x86/x64, not ARM. Same reason why Windows RT & Pro aren't the same. Pro runs on x64 and can run normal exe's. RT runs on ARM and can't run native windows programs.

And even if it was compiled for ARM, it won't run on Android. EXE is an Windows executable and depends on the Windows runtime libraries.
It would be nice to see someone developer a full blown version of Wine for Android, or if companies like Codeweavers can make CrossOver for Android to allow the use of .exe Windows applications.
I know this is not impossible and very possible if Android is really just a Google controlled version of Linux.
My first and only paid $ purchase of Linux was Xandros 2.0 desktop OS, and one of that OS main selling features was that it had Crossover integrated into it. I could download .exe's and install them on Xandros and run Windows apps. :laugh:
You're looking at two different processor architectures on two different operating systems. You would need a whole lot more than just a crossover/wine for Android. Consider purchasing the Asus Vivo Tab (not the Vivo Tab RT) if you have to run .NET/win32/WinRT executables. Also consider if android has equivalent apps that suit your needs. What kind of Windows programs do you use?
Update:
https://play.google.com/store/apps/details?id=com.max2idea.android.limbo.main&hl=en
If you ran this, installed Trinux on it and ran wine/crossover (provided they even support Trinux) you MIGHT have a chance at running windows apps. But it will likely be insanely slow.
The other option is to buy a new server, install Windows Server 2008/Server 2008 R2, buy a router that supports VPN, get a really good internet service (preferably with symmetrical data rates), buy the XTraLogic RDP app for android, tunnel into your VPN from your android device, set up terminal services on Windows Server, buy one Terminal Services Client Access License, configure RemoteApp in terminal services and run the apps using XTraLogic RDP on your android from your windows server. You would have to keep the server running 24/7.
My point being, even if you could pull this off, it would be incredibly impractical. Consider alternatives, like equivalent apps for Android or an X86 tablet.

Hi everyone.
Could anybody compile BlueStacks App Player for Windows RT?
It would be great to use this app on our tablet with Win RT
I use on my laptop (win7) and wish o use on my Surface RT
Official site
Thanx a lot
It would be a great app to have, but seeing that it's not open-source there is about zero chance of it ever getting ported by the community.
Your best bet is to just hope that they (the actual makers of the app) decide to bring it over to RT, which is possible but unlikely.
Search next time; the devs here are up to their ears in requests for closed-source applications and are pretty fed up with it. Sorry.
They've actually already stated that it's coming...
Not explicitly. They hinted at it in a Help forum post, but never confirmed or denied it. And that was months ago.

Actually they had listed on their site that they were working on an ARM version.but not sure if they still are. Seems unlikely MS would allow it in the store due to direct competition with the windows store.

MS doesn't have a whole lot of control of things outside the Store. They could side-load an app pretty easily.
The vast majority of RT devices aren't "jailbroken" for sideloading arbitrary ARM binaries. Also, remember that RT doesn't (currently) support OpenGL, which means any Android apps/games that use advanced graphics won't work unless BlueStacks write and include an openGL-via-DirectX compatibility layer.

I meant side-loading a Metro app, which can be done by just about everybody.
Cant sideload metro apps without a developers certificate
Derp. Yes, of course sideloading is the obvious way to go about it. Getting the dev license is easy, and yeah BS would have to sign their app, but that's not exactly difficult and their cert doesn't have to be signed by anybody else; it just requires that the end user install the cert before the app if it doesn't already chain to a trusted authority. The appx installer script automates all of that, though.
That said, the OpenGL issue is still there. Don't count on 3D games, at a minimum, working.
Don't forget however, that all of this is pretty much irrelevant right now. The Surface lacks the power to run Bluestacks. On my 6-core 2.3 ghz 6 gigs of ram computer with a great graphics unit, Bluestacks is still relatively slow. Just imagine it on the quad-core 1.4 with 2 gigs of ram that the Surface has. Not to mention it's on ARM, which is considerably less powerful than x86 or x64.

I dont think bluestacks is a multithreaded application in which case your 6 cores would be irrelevant and it would be purely down to your 2.3ghz clockspeed, which is not high at all. 6gb of RAM would also be irrelevant as no android app requires that much RAM so it simply wont be needed. GPU, not so sure what happens there, most of the apps I try running dont seem to enable my GPU at all so I am not sure if bluestacks is using software or hardware OpenGL, but then I havent tried any 3d games or anything. It runs ok on my 3.5ghz AMD athlon 2 but its not always as perfect as lets say a nexus 7 tablet running android natively.
I'm admittedly not 100% sure on how BlueStacks works (is it a native x86 DalvikVM, or is it emulating a full ARM system?), but it should be, at least in theory, possible to get it to run as naively as it does on Android by just porting the DalvikVM to Windows RT. That should result in speeds at least similar to a lower end Android tablet (Windows is bigger and has more cruft than the linux kernel that's running the DVM). With some sort of reverse WINE scenario it should also be possible to get a degree of binary compatibility for native libraries/addons.

Sort of, yes. But still, that means the Surface would be way less powerful. Also, my RAM is EATEN by Bluestacks because it's not apps that are the problem to run, it's Android. You're basically loading an entire virtual machine onto your RAM to run, in a program shell, then running Android apps on top of that. So the power of the device does matter... however:

Bluestacks would have to run a full emulation of ARM in order to run all apps, right? Because when you install native x86 Android, it runs very few apps from the store, because they aren't compiled for ARM.
Netham45 could be right though that we could kind of make Android run natively, though I'm highly dubious about it happening through Bluestacks. Bluestacks most likely won't make an ARM port (especially cause I doubt Microsoft would allow it in the store) and if we did have access to source code, it's still built around running on Intel processors, and would probably have to go through all sorts of unnatural emulation... So making a totally separate Android program from scratch (which would require inordinate amounts of work) would probably be the best bet.
No. I think bluestacks is actually "just" a port of the dalvik VM to run on windows.
Android apps are not compiled for a specific CPU type. They are compiled for the dalvik virtual machine which is in a way similar to the java virtual machine, in fact a dalvik applications source code is java source code hense why many people say android apps are java, in reality the dalvik VM is very different from the java VM and the 2 are not compatible.
The vast majority of apps do actually work on x86 just fine.
The main problem is that google restricts apps based on your device and often it doesn't recognise x86 devices so doesn't show results, the default app manifest files don't actually restrict platform but many devs set them to arm for some reason. With various tools to spoof what device you appear as you can still gain access to thses other apps.
The problem apps are those that use the NDK (a small minority). NDK apps do have native code, but not just for ARM. The NDK default settings are to generate binaries for ARMv7, but it can be set to x86, ARMv6, MIPS or to compile multiple binaries for a mixture of the above (causes its own issue as it includes the binaries for all platforms in one APK which loads the relevant binary at runtime, good for compatibility as one APK covers all devices but makes the final APK massive). x86 devices of course cannot run ARM compiled apps which does include a few big name apps.
I don't know if bluestacks has left it as pure dalvik VM on x86 or if it does include an ARM emulator for the NDK but it certainly isn't just running an ARM emulator and tyen android atop of it.
I don't experience the ram eating effects you mention either.

That's exactly what my understanding was as well, although what I'm about to say somewhat contradicts that.
Interestingly, http://www.bluestacks.com/technology.html says that BlueStacks is "fully configurable" and that it "supports" Windows on ARM as well as x86 Chrome, even though neither of those are actually available today. So, not sure if that page is before or ahead of its time.
"BlueStacks employs a lightweight, optimized, soft hypervisor with deep enhancements to support "embedded virtualization". End consumers can enjoy the full Android environment through BlueStacks, or just install Android app icons directly on the Windows desktop."
What the page basically says is that the core virtualization that BS uses is very easily configurable to different combinations or permutations of OSs; that the technology can just as easily run Windows on Android or Android on Chrome as it can Android on Windows, which is the only current release. It also implies that BS can do BOTH a mere dalvik vm (just install apps to the Desktop) as well as a complete system emulation (full Android experience).
There may be hope for RT yet.
As far as I remember, Bluestacks is using QEMU as there base platform. So it's probably still running ARM code in emulator.
I am looking at if we can port the Dalvik VM over to Windows RT. Anybody want to join the explorations?
So far I can see the Dalvik VM has lots of generated ARM assembly code and have huge dependencies on linux.
Porting would need quite a bit of effort.
Developers from Windroy has done it for the Windows X86 platform. If they can do it for Windows RT, it'll be much easier.
Basically, on the Mate site there is now a Mate download for the GPD Pocket, which does look like a cracking good machine.
Basically, has anybody had the gumption to try this on their Gemini? I have only one Gemini and don't have the skill or the courage to do this myself. If, and it is if, Mate worked on the Gemini, that would be excellent. I know people have Debian working, which is the fork for Ubuntu, which is the fork for....... which is why I'm thinking / hoping it may work.
Thoughts from anyone?
P.
GPD Pocket runs on an Intel x86 processor (like most computers and laptops), which means that it can basically run anything available. Gemini runs on ARM, which is basically the processor that powers mobile phones and some tablets. ARM is a completely different architecture and is not compatible with x86 software. Most of the desktop operating systems (like Windows, mac OS, Ubuntu, etc) focus their development on the x86 platform, since the vast majority of desktops use this architecture of processors. Because Linux is a free and open source OS, it is possible to get the kernel source code and (with a few modifications) compile it to a different architecture. That's what was done for the Gemini (and all other ARM devices that can run Linux), they got the Debian source code and compiled it for the ARM cpu. Some specific hardware settings and drivers were added for the Gemini PDA to make our custom Gemian, a Debian for the Gemini. Ubuntu is based on Debian, and not the other way around. So, to have Ubuntu Mate running on the Gemini requires one step further, to get Ubuntu source code and Gemian customization and drivers, mix it all together to make some "Ubuntian" of some sort... Honestly, I see no advantage in running Ubuntu, since Debian is the root of it. I don't know of a thing you can do on Ubuntu that you can't on Debian. But still, if you really want to have Ubuntu Mate running on your Gemini, on the Android side you can install Linux Deploy. This app only works on rooted Android, but it is totally worth it if you want to run Linux on your device. It allows you to install several distributions of Linux on top of Android, including Ubuntu Mate.
