I was wondering if it was possible to use QEMU to start the emulator created from the Android Virtual Device Manager in Android Studio? I know it can be started from the command line, but I'm trying to understand how it works underneath. I know the AVD creates a qcow2, but it also creates a lot of other .img files that I'm not sure how to combine into a command that can actually start it.
If I can't start it via QEMU, is it possible to create an Android qcow2 emulator image to run for device testing in the same way? I found a similar guide online (https://yzygitzh.github.io/android/2017/11/03/android-x86-qemu.html), but I haven't gotten it to work so far. I also don't know how it would perform in comparison, specifically for app testing. Would anyone have any insight on that?
Similar Research:
Android emulator is based on QEMU. Can I use KVM with it? (Kind of beats around the question, but doesn't exactly answer it)
Mount qcow2 image created by Android emulator (Discusses a bit about the Android Device Emulator files)
How to show which options are passed to QEMU when launching the android emulator? (Seems closer to partially answering the question)

I have a mid 2013 Macbook Air (so I should have the resources to make the emulator work) and I'm trying to get the Android Emulator working. It's been half an hour and the color pinwheel continues to spin. In the meantime I looked up and downloaded Andy and BlueStacks Android emulators but Andy was nothing more than a clock with no buttons and BlueStacks, while it had a number of options there was nothing that seemed evident that I could get 'Hello World' running from the basic tutorial.

I want to progress but I'm stuck. Thanks.
I would look into Genymotion. They have a great android emulator that can spin up vms for different phones. Its free for personal use and easy to use. The VM image is download directly from their server so when it gets corrupted you can delete it and add it again.
It is also recognized by Eclipse and Android Studio.
There should be two downloads, one that includes Oracle VM and one that doesn't. I recommend the one that does so you do not need to install Oracle VM by its self.
If that doesn't work post a comment and ill see what I can do.
try restarting your computer..
When you start an emulator you should "Store a snapshot for faster performance" in the Android Virtual Device (AVD) configuration or the emulator won't start at all. After too much time troubleshooting, it was as simple as that.
I'm new to using Android but am trying to take some screenshots using the Android SDK and the emulator.
I've managed to install the SDK on my mac, create an .avd (using one of the pre-configured device options) and can run it using the commands
./emulator -avd AVD_for_7_WSVGA
At this point i'm stuck though.
It seems like I can install my application I'd like to take screenshots of using avd, like this
./adb install /path/to/my.apk
2034 KB/s (17283416 bytes in 8.296s)
success
But cannot manage to get beyond the initial screen, the only other screen I can access is the other one I've included in this post.
Could anyone point me in the right direction to begin using the Android interface?
There is no bar at the bottom with home buttons etc, & I was hoping that there might be some default applications in the emulator such as a browser.
Thanks
So i'm having awful trouble trying to get the Emulators in the Android SDK to start up. I can create the AVDs just fine, and then when hitting the 'start' button from the SDK Manager, bring up the small loading console window, indicating that the emulator is launching. However, after that, nothing happens!!
I have read many threads and posts with people having the same problem, maybe to do with the settings requiring too much memory, with some people waiting 30 minutes for the emulator to load!!
When trying to run the AVD emulator through terminal, I simply get a 'Bus Error' with no further indication of what could be going wrong...could it be a memory issue?
What I did to get where I am now:
Download the Android SDK package for Mac. I'm extracting the sdk only, not eclipse. I'm on Mac 10.6.8.
Install the SDK, and download the latest version of Android in the SDK Manager, along with default tools.
create a AVD and hit start.
window pops up to boot the emulator, that process is complete and window closes.
Nothing happens.
My knowledge of the sdk tools are very limited, all I want is to be able to do some testing...
Any help greatly appreciated!
Thanks
Actually, the simplest way to get emulators running right now is probably GenyMotion. They provide an interface, and pre-configured emulator images to make it pretty simple to get running.
This is not an endorsement (I use the standard ADT myself) but a lot of people find their tools useful.
Here is my suggestion: instead of using AVD, start using espresso and virtual remote android hardware emulator from Google servers - also known as android-test-kit. You will have the possibility to run and test you App on several different devices, without the need to spend money on actually all different devices for developing and testing purposes before releasing your Apps. You find further details here:
android-test-kit
Why Espresso
The 2 videos are somewhat long, but worth watching.
Taking this approach will solve your problem, save you money, and improve your productivity.
I run into the same issue on my mac 10.6 and it only works if i do
emulator64-x86 -avd my_android
Besides, my virtual device has to configured using x86 but not ARM
maybe this link can help you.
I'm using IntelliJ Idea 13 to develop Android applications on Ubuntu 12.04 64-bit. But my virtual device never starts despite there is no error.. its screen always stays like this:
My Android target level is 4.4 (API 19). How can I solve this issue?
Edit: Here is my AVD details:
I Recommend you look at this post to a similar question.

they are using eclipse but you should be able to view the logcat, other posts say first load can be ridiculously long.
the spec of your PC may come into play as this post https://superuser.com/a/347298 explains the way the emulator converts to arm opcode: direct quote:
To use emulator more effectively, this is my experience:
Don't close emulator everytime you run your application.
Scale the emulator screen smaller.
Disable snapshot (Yes, it's useful but it takes time to close the emulator).
Specify a file path for SD card image file. I use only one SD card for many AVDs.
If you got any problems in adb, just reset adb, don't close emulator.
Open few programs in your operating sytem.
If you are using Windows, don't ever close emulator. Do it combined with Hibernate of Windows.
My AVD has started after I check "Use Host GPU" option from "Emulation Options".
I want to be able to develop and immediately run android apps on my device. I've played with sl4a and a bluetooth keyboard, but the app and ide weren't designed for what I want to do with them. what are my options?
clarification: I want a mobile dev env that doesn't involve any computer (other than my android device). I'd like a simple code editor, like emacs or scite ideally, and some kind of complete interpreter or compiler for the full android api that runs on the device. I'm dreaming, clearly, but how close can I get to that today?
I've gotten Vim working really well in ConnectBot on my Milestone. I needed root privileges because of where I put the files, but you might be able to find a work around without it.
See this link:
Native Vim for Android
See also my comment after the post. I've got $HOME setup on my sdcard, and a bunch of Python plugins and colorschemes in ~/.vim/ and everything just works.
Of course this requires you to be comfortable working in Vim... I've gone back and forth with it several times in the past. It is very strange, but once you pick up a few habits and figure out its odd vocabulary it is very nice to use!
I got a pure python version of Mercurial working on Android too. It was a pain, but now I can push and pull code from my repositories and keep my /sdcard/sl4a/scripts/ folders in sync with my latest changes. I documented some of what was necessary in a bug report to py4a.
Canonical just announced that they will be bringing Ubuntu to android devices. Hopefully this will help....

Like FrinkTheBrave said, you can use an ide (Eclipse is perfect, because of the Android Development Tools, but you could use any other program.
If you work on Windows, and after installing the USB driver, you only need to plug your phone to the usb and hit Run (or debug), and Eclipse will copy the apk into your Android and start running. It takes less than 5 seconds.
If you work on a Mac, you don't need to install anything, just plug in the phone and it works =D.
Well, in Linux it is a bit more complicated (though not impossible, I actually work with Linux), but you can still develop there =).
Cheers
BIG BIG EDIT
I've seen today just what you asked few time ago. Here, take it: https://play.google.com/store/apps/details?id=com.aide.ui It's obviously hard to type on a smartphone, but it could do the trick on an EEEPad transformer. Have a good day
I'm not sure about developing on Android, but you can use one of the sdks available to write your code, then copy the apk onto the device via usb and install and run it.
It takes less than a minute from saving the source code to running on the target hardware.
I use the sdk at developer.android.com and eclipse on windows xp, and use AndroZip on my phone to install the sdk. simples ;-)
I've not looked into using usb debugging, but that could be even better.
