Install Android Studio on CloudReady (Chrominium OS)

Yesterday, I replaced my Win7 OS with CloudReady (similar to Chrome OS which is developed by Chrominium Project). Now I want to develop Android Apps. So, how can I Install Android Studio?
Link OS which I'm running, and want to install Android Studio: https://www.neverware.com/freedownload
If you are using the 64bit version of CloudReady, you can install it via a flatpak.

Why is Android Studio not finding the x86 emulator when running a flutter app?

Software
MacOS Sierra 10.12.6
Android Studio 3.1.2
Flutter 0.3.2 • channel beta
Tools • Dart 2.0.0-dev.48.0.flutter-fe606f890b
Flutter doctor (no problems found)
Problem
I am using Android Studio IDE to develop flutter apps, but I can't get any of the Android virtual device emulators to launch from the IDE. Whenever an Android virtual device is selected, such as the Pixel P, an error message appears saying "PANIC: the emulator program for the x86 CPU is missing". However, the emulator does work when it is launched from the command line:
$ cd /Users/$USER/Library/Android/sdk/emulator
$ emulator -avd Pixel_API_P
The problem seems to be specific to flutter projects, given that the same virtual devices are being launched normally with Android projects.
I changed the virtual device's x86 image to x86_64 and the problem was solved. Still don't undertand the underlying cause, but it worked:
ADV Manager > edit device > (name_of_device) Change... > x86 images > download & select x86_64 image
Check if your GPU rendering is activated in your BIOS settings.
Generally the BIOS keeps the GPU rendering off. You can change it, then clean your Android Studio, then reload your ADB.
Hope this helps. :)

Genymotion works well, but start Android Studio Plugin show error: 'unable to start VirtualBox'

I've installed Genymotion and VirtualBox on ubuntu 16.04 LTS and everything goes fine. Genymotion works well.
Then I installed Genymotion Android Studio Plugin,but when I clicked 'start', it shows: unable to start VirtualBox
Run Genymotion directly it works well, but Android Studio Plugin goes error,It is not like this: Genymotion error at start 'Unable to load virtualbox',how to fix it?
Watch this,run genymotion directly works well, but run android studio plug it shows: 'unable to start virtualbox.'
Open Genymotion -> Settings -> ADB -> Use custom Android SDK tools -> locate your SDK.
You have to use the Genymotion SDK as that of Android studio.Try it hope it helps !!
If you don't have geni virtual box installed, install it.
Your error says that you don't have your virtual box installed in your PC .
If you have then you have not given the right path click on geni icon and set path of it where You installed
(by default its like /Applications/Genymotion.app).you can read here)
Installing it on your pc won't be enough .You need to apply the plugin in android studio as well.
Go to File>settings >(search for plugins in your left side)>select the option plugin > browse repositories > and install geni plugin and you are good to go!
Restart android studio.
Finally if i missed anything watch this video for full thing
Edit:If your are using a V.Box
Go to Network and Sharing Center > Change adapter settings and enable these:
Local Area Connection (if it's disabled)
VirtualBox Host-Only Network
I think that enabling the second will do the job, but I did the first anyways.
read More details --------> Unable to start Genymotion Virtual Device - Virtualbox Host Only Ethernet Adapter Failed to start
Hope it helps.
Try uninstalling your current version of virtualbox and install Virtualbox version 5.0.28 from here: https://www.virtualbox.org/wiki/Download_Old_Builds_5_0
The way around the error is to:
1) Click on the Genymotion Device Manager in Android Studio. Once the Genymotion Device Manager window pops up, you will see your virtual device/devices, and its/their status should be "off".
Genymotion Device Manager
Virtual Device Status is off
2) Now, go run Genymotion outside of Android Studio.
3) In Genymotion, click on your virtual device to select it and click on the start button at the top left corner to start the virtual device.
4) Once your virtual device is up and running, go back to the Genymotion Device Manager window in Android Studio and click on refresh. You should see that the status of the virtual device is switched to "on". Now, you can run your code directly to Genymotion.

/dev/kvm not found in Android Studio (Windows 10)

I was using Android studio on windows 8.1 and it was working fine. Now I upgraded to windows 10 with a clean install and installed android studio. When I open AVD manager and creates a new emulator, it says /dev/kvm not found. I tried these after googling but nothing worked for me-
Go to sdk\extras\intel\Hardware_Accelerated_Execution_Manager and install intelhaxm-android.exe
Download a fresh copy of Intel HAXM and install, but it says failed to configure driver: unknown error. failed to open driver.
Re-install HAXM from SDK manager, but it says Windows blocked the installation of a digitally unsigned driver. Uninstall the program or device that uses the driver and check the publisher's website for a digitally signed version of the driver
Downloading workground patch for HAXM, extract to haxm folder and Run as administrator.
My System
OS- Windows 10
Processor- Intel Core i3 third gen
Intel Virtual Technology already enabled from bios.
Hyper-V is also unchecked
I found that, when I start my PC by disabling driver signature enforcement, the emulator is working fine..
At least its solved i justa instled the new HAXM version 6.0.4 at this will work:
Here is the link:
HAXM v6.0.4
