The IDE does not let me open more than 2 AVD simultaneously. After 2 are already running and attempting to start 3rd AVD - Android Studio displays the message "Starting AVD", but when loading ends nothing happens. No logs, no errors.
If, for example, you choose to close one of already running AVD, and start another - it starts properly, i.e. all AVDs behave well individually.
If matters, I use:
Nexus 6 API 23 (Android 6.0 Google APIs), x86;
Nexus S API 22 (Android 5.1 Google APIs), x86;
Pixel API 25 (Android 7.1.1 Google APIs), x86;
Android Studio 2.3.1
Have same problem today and found it related to RAM usage limit for HAXM
Found answer at here
Why launching more than 2 AVDs works only under specific conditions
Reinstall HAXM and set more ram to fit your need

I'm trying to do some React Native development for Android.
In the past I've been able to run and use a couple Android Emulators on my machine. Now, when I start the emulators I see them launch successfully, but I don't see them appear on my screen:
I'm running
Edition Windows 11 Pro
Version 22H2
Installed on 10/5/2022
OS build 22621.1105
Experience Windows Feature Experience Pack 1000.22638.1000.0
and
Android Studio Dolphin | 2021.3.1 Patch 1
How can I view the running emulator?
I found that if I clicked this tab:
The Emulator would appear as a tiny (maybe 20 x 20 pixels) window on my other monitor. I then was able to make the window bigger and use it.
First post--be gentle. Can't find any posts on Android Studio 4.0, so I hope this isn't a repeat. I updated Android Studio from 3.6.3 to 4.0 on Windows 10 (1909). Had created a couple of virtual devices in 3.6.3 (a Pixel 2 running API 28 and a Pixel 3 running API 29)--both worked great in AS-3.6.3 and I could develop apps, compile, load, and run them with no problem.
After the update to AS-4.0, the virtual devices no longer appear in the devices box at the top of the GUI--it just says "No Devices". When I open the AVD Manager, I can see them, and I can start them (although when I start them I get a pop-up saying "AVD Manager: Unable to locate adb"), but I can't get any code to download and execute on it. On the Pixel 3 emulator, I also get another pop-up saying "Detected ADB: Could not automatically detect an ADB binary.", and it gives instructions to resolve it, which don't make any difference (jump into extended controls and toggle "Use detected ADB location").
When I try to open a past project and run it, I get the same behavior--no devices found.
I've also tried making new emulators, hoping the new setup would recognize them, but to no avail. Tried starting and restarting AS, as well as the computer, also to no avail. I have Android SDK Build-Tools 30-rc4, the latest Android SDK Command-line Tools, Android Emulator 30.0.12 Android SDK Platform-Tools 30.0.1, and the Intel x86 Emulator Accelerator all installed.
I've Googled and spoken words of fierce power over this for several days now. Any suggestions for how to get AS-4.0 to recognize the emulators? I've resisted uninstalling everything and starting over--was hoping it was just a configuration thing.
Thanks in advance,

After some more Googling, I found the answer here (I think my constraint of wanting an answer for AS-4.0 specifically kept me from finding it):
Could not automatically detect an ADB binary - Android Studio
I had to redownload the SDK platform-tools zip file and reinstall it. I don't know why the old one got messed up with the migration from AS-3.6.3 to 4.0, but there you go--such is life with complicated software.
As soon as I replaced the old platform-tools directory with the new one, all my old emulators showed up and I was back in business.
Thanks anyway!

I am trying to run my app on canary build of the android emulator from android studio on AMD processor but I am getting the following error
1:47 PM Emulator: [2440]:INFO:android/android-emu/android/verified-
boot/load_config.cpp:236:Verified boot params were not found.
1:47 PM Emulator: **
1:47 PM Emulator: ERROR:/usr/local/google/buildbot/src/android/emu-master-
dev/external/qemu/fpu/softfloat.c:486:round_canonical: code should not be
reached
1:47 PM Emulator: Process finished with exit code 3
I got to know about the canary build of the android emulator for AMD processor from here. My virtual device' CPU/ABI is armeabi-v7a. I searched for what the 'exit code 3' for the emulator mean but I didn't get any solution.
Can someone help me please!
I got the android emulator working today.
I have done the instalation process for canary build of android studio from the beginning:
1. Enabled "Hyper-V" and "Windows Hypervisor Platform" in "Turn Windows features on or off" settings of Windows. This has been explained in here.
2. Downloaded the latest Canary build of Android studio from here.
3. After downloading the zip file I followed the guidelines in here under "Install alongside your stable version" heading. The guide lines are:
a. Unpack the ZIP file.
b. Rename the resulting folder to something unique like "Android Studio Preview."
c. Move it to a permanent location, such as next to your existing Android Studio install in C:\Program Files\Android.
d. Inside C:\Program Files\Android\Android Studio Preview\bin\, launch studio64.exe (or if you're on a 32-bit machine, launch studio.exe).
4. After launching studio64.exe I got a pop-up message to update Android emulator. After the update I created a new virtual device with an image of x86 with android 9.0. I started the android emulator to test my app. Though I got the
Verified boot params were not found
popup error message initially, the emulator started functioning well.
I am a very new Android developer and was until today having the same issue as yourself. Here is how I got it to work (Please note I am also on an AMD system).
Make sure you have enabled Hyper-V and Windows Hypervisor Platform. If you type "turn windows features on" in your run bar you should be able to locate it. Also enable virtualisation in the Bios. Mine comes under "SVD".
(Please note after this step I was still experiencing the problem but this is a pre-requisite).
Delete all devices from the AVD manager.
Install a new x86 device from the AVD manager. What I did here was select a version down from the one I was previously getting issues on so Oreo from Pie. When it asks to confirm if you want to wipe the user data please confirm positive.
Once setup, run the device from the AVD manager. It may ask you if you wish to enable Instant Run. I elected to disable this. (I had enabled it when I first was trying to run a device).
You will still receive the 1st error regarding no boot parameters but the emulated environment should load. You can now run the APP and it should install the APK. Previously due to the device not coming online properly, the APK would not install. I can also now setup a device on Pie without experiencing the issue so I think it may have been the wiping of the previous data that helped.
I wish I could tell you WHY this worked for certain and previously it would not work, sadly I cannot but hopefully this will get you working.
I recently upgraded Android Studio to 2.0 (Windows) which broke the emulator.
The symptom is that the emulator starts a (single thread) process that takes about 100% of its CPU. Nothing shows on the screen.
Of course, this worked like a charm before the update.
Few things I tried:
Used an AVD created before and after the update
Increased AVD memory to 1G
Delete / Install Android Studio
Used different CPU Architecture (Arm & x86)
Used different versions of API (21 & 23)
I had the same problem I had to reinstall android studio all over again, After that open your SDK monitor press on launch stand alone SDK manager, There scroll down and check if the emulator is installed properly if not install it.
I hope this answer helped you since that's what I did and it works.
A temporary solution:
Go into the AVD Manager, select the Virtual device, and click "Edit"
Find "Emulated Performance" -> Graphics, and switch that from auto (or hardware) to Software.
It won't have quite the performance, but this worked for me. Seems to be that Android Studio 2.0 doesn't play well with certain graphics cards or something.
I'm new with Android studio (2.0) and android app. I downloaded android studio 2.0 two days ago and started my first application "Hello world".
When I start the application on my tablet, the application work fine and evrything seems valid.
When I start the emulator nothing happend and I don't have error messages. The emulator start but no popup windows appear. I try to understand why but without error messages it's not easy (and I'm a starter :-( )
My pc is Intel R Core CPU 3.00Ghz with 8Gb ram. Windows 7 (system type 64 bit)
I use Android studio 2.0.
The option Tools- Android - enable android ADB integration is check.
The application compile.
When I start the application with the emulator, I have this message:
c:...\AppData\Local\Android\Sdk\tools\emulator.exe -netdelay none
-netspeed full -avd TAB.
After a short time, I have the message
Waiting for target device to come online
(I cann see a process when I start the task manager" but nothing appear and I expect a popup windows to test my app.
This is the info from the sdk manager:
Can you help me ?
