How to resolve error message: "This AVD may not work unless you install...first"?

I'm trying to create an AVD for Android 5, but it's giving me a warning
This AVD may not work unless you install the Google APIs Intel Atom (x86) system image for Android 5.0 (API 21) first.
But I have that installed - this is a screenshot of my SDK manager with the correct System Images installed:
And this is how I'm configuring my AVD:
Am I doing something wrong? How can I get this to work?

Install Android SDK Build-tools 21 or higher
and check Use Host GPU

Finally I managed to resolve this issue manually...waiting for a fix by Big G:
Searching between all the various .ini files generated by Android AVD Manager, I found hardware-qemu.ini(its location is %USER_FOLDER%/.android/avd/yourAVDName.avd/hardware-qemu.ini).
It contains a row starting with kernel.path pointing to the wrong google apis location. Once changed it with the right one
(e.g. path_to_android_sdk/system-images\android-19\google_apis\x86/kernel-qemu for Google API 19 version)
the emulator started with the right Android version, containing Google APIs.
Hope this helps all Android developers :D

You will need to install the HAXM driver on your machine in addition to downloading the components. This step is done outside the Android tools.

no cpu/abi system image available for this target

I'm getting this error when trying to create a virtual device (I'm brand new to android development, following a tutorial to get everything set up).
Everything I found simply said install the ARM or Intel System Image for the target that you're using.
I installed both of these for Android 4.4W (API20) and all 3 for Android L (API 20, L Preview) just in case. I also tried having only 1 system image for each installed in case they somehow could interfere with each other, but that didn't work.
If anyone has any ideas what else I'm missing, that would be great!
Thanks

The SDK just got dumb, remove the images and reinstall.

As stated by James here:
Simply because CPU/ABI says "No system images installed for this
target". You need to install a system images.
In the Android SDK Manager check that you have installed "ARM EABI v7a
System Image" (for each Android version from 4.0 and on you have to
install a system image to be able to run a virtual device)

Successfully Running an Android AVD Manager and creating new Emulator

So I am a beginner to Android development and decided I would start learning based on the Android site itself how to make android apps. I thought a good place to start would be making my first emulator and running a minimal hello world program.
Using the Android Guide:
http://developer.android.com/tools/devices/managing-avds.html
It instructs how to make an emulator but the appearance of my AVD is radically different than the one they are using and I have encountered an error with it which I cannot find online literature to fix:
Specifically the process they give to make a new virtual device is hit "new" (in my case I am guessing that is the same thing as "create" since there is no "new "button on the most recent version of AVD manager)
And after that a form appears, I am supposed to fill up the form with relevant Virtual Device information and hit "ok" to create the device.
Except... after filling all the information I still cannot hit "ok". The button is greyed out, and I have done everything exactly as the android guide told me. What should I do to fix this? I have the form displayed below notice the greyed out ok button on the bottom right corner.

The problem is in the field: "CPU/ABI: No System images installed for this target". To rectify, open up the Android SDK Manager and download/install a System Image.
For example, when I open the Android SDK Manager, I expand the Android 4.4.2 (API 19) and install the ARM EABI v7a System Image (and for giggles, I might install the Intel image as well).
Whilst there, make sure you have other bits you might need for development (but not necessarily for the emulator) like the SDK and I'd definitely recommend downloading the sources, samples, SDK Tools, SDK Platform-tools and SDK Build-Tools.
You can use a later API version if you like, but API 19 has been released into production at the time of writing.
After which, you can restart the AVD and you'll be able to select the a CPU and create the emulator.

I suggest you should add all the "Android System Images" to your Android SDK Manager.
For that,
Open your SDK Manager from Windows -> Android SDK Manager.
Now expand each Android API versions then check Google and Intel X86 both system images and also check Intel HAXM Installer in the Extras.
Download and install them.
After successful install, the status changes to be as "Installed".
Try this also:
Now if your system have a Processor that have a feature called as Intel Virtualization Technology, then Intel X86 images will be huge benefit for you. because it supports Intel® Hardware Accelerated Execution Manager (Intel® HAXM).
To check that your processor support HAXM or not : Click Here
You need to manually install the Intel HAXM in your system. Follow these steps for that.
First of all go to - adt -> extras -> intel -> Hardware_Accelerated_Execution_Manager
Make sure that Intel Virtualization is enabled from BIOS Settings.
Now install Intel HAXM in your system and select amount of memory(i prefer to set it as default value).
After installation create new AVD which should have a Target of API Level xx
Now set the CPU/ABI as Intel Atom(x86).
If you are on Windows then do not set RAM value more than 768 MB while setting up an emulator.
Run the emulator. It will be blazing fast then ordinary one.
Hope it will be helpful for you. :)

Cannot create/edit AVD - 'No CPU/ABI system available for the target' - error

I've tried installing system image ARM EABI v7a system image (and all other System images available in SDK manager)
I can't create or edit AVD. but I have Two AVDs already which is working still.
if any details needed I'm happy to provide....
Thanks in adavnce,

couldn't find a Solution still , What I did was unZip the ADT and install it all over again

How do you create or find a "userdata.img" file for ABI armeabi to copy into the AVD folder

I am running the Hello World Android SDK test on Eclipse. After I installed the latest platform for Android SDK I tried to create an AVD.
In Eclipse:
Selected Window > AVD Manager.
Click New....
The Create New AVD dialog appears.
Type the name of the AVD, such as "my_avd".
Choose a target.(latest platform)
Ignore the rest of the fields.
Click Create AVD.
But when I returned to Eclipse I got a red error message saying:
"unable to find a "userdata.img" file for ABI armeabi to copy into the AVD folder.
I have a windows vista 64 bit, Eclipse 3.7.2, and Android platform 4.0.3. If anyone could please help me, I really appreciate it. If you might have an idea of what I might be doing wrong I am all ears. :)
Here is what I have been trying to do http://developer.android.com/resources/tutorials/hello-world.html

Click on Android SDK manager in eclipse..
Then in Android 4.0.x your version.. click on ARM EABI v7A System Image.. and click on Install package..
It should work then...

just for the record: i had the same error and couldn't solve the issue with the tipps here. in the end i found out, that i didn't made a choice in the CP/ABI dialog after creating a new device with the avd manager.. (this field was left open in a tutorial i found....)
Actually, Need to Android 4.0.x your version.. click on ARM EABI v7A System Image.. and click on Install package.. as per Raju.
After that I followed the advice of making sure that I filled out the CPU/ABI field and then all was good.

if you have installed "ARM EABI v7A System Image",still didn't work then try "android update avd -n h" in shell(h is the name of my android virtual device,repalce it with your specific avd name)
