SYSTEM UI is not responding error message in Android studio

I am facing the same problem. I have ASUS ROG 17 inch Laptop, 16GB RAM, i7 processor, nvidia graphics card 3gb RAM , Windows 7 Home Edition service pack 1, Android studio 3.62, HAXM 7.56, Android Emulator 30.0.5, Android SDK 29.0.6. When I starts my emulator, nexus 6p API 28, Android 9.0, it tooks almost 3 to 4 minutes. and after booting it display message, System UI is not responding,. Wait or close app. When i click wait, it will took a while and starts successfully. But sometimes, It won't. I have to close Android Studio, shut down the system and restart it again. I wondered, why its not working smoothly on such a high configuration laptop.

The solution is that you can't do anything about it. You have assigned 2GB of RAM, but that's too low for the emulator (though it shows that as recommended).
The only way about it is to create and run a new emulator with the default configurations, i.e. don't change anything in the memory or RAM section.
This solution worked for me although the performance of the emulator isn't too good.

Android Emulator Shutting down in few seconds after launching

Well I created a new AVD from AVD manager that is "Nexus 5x API 25". When I Launch the AVD in emulators it gets launched and stay for while (30 Seconds) and Shutdown Automatically.
I tried editing the Ram Size in Config.ini of AVD, but still the same problem.
My computer Configurations are:
Intel Core i3
Ram Size: 4 GB
HDD: 500 GB

Solution.1
By setting the Graphics option on the Android Virtual Device to Software instead of Automatic or Hardware. Once you did that the emulator device started up great and everything worked.
Or
Go to Menu->Tools->Android and uncheck the option Enable ADB Integration Run the application. Now the emulator will be launched, but app will not run. Once the emulator is fully launched, check the Enable ADB Integration option and re-run the app. Now the app will be launched in the already running emulator.

My Android emulator was shutting down almost as soon as Android Studio started it.
I went to the Android Virtual Device Manager and under "Actions" for the misbehaving virtual device, I selected "Cold Boot Now". This seemed to resolve my problem.
I am using Android Studio 3.1.4.

I'm in the same boat with a late 2019 version of Android Studio (v3.5.2), and I've been using it a couple of years, so it seems like a new problem to me. I am able to resolve it by either 'wipe data' (undesirable, often) or 'cold boot' (from tools->avd manager) and then running the app. However, this is not a permanent solution, because it always comes back. I usually wind up doing the cold boot thing once, then be careful not to close the emulator while I am debugging so it is good until next session.
I will note i noticed Android Studio was HIGH on memory usage (which is more difficult to notice in SSD times, because you don't "hear" the hard drive thrashing from swapping memory.) Android studio itself noticed the abnormally high memory usage and reported this to Google (presumably). I wonder if low physical memory is/was the issue.
Update: I just had a BIOS update for my notebook, and afterwards, I do not seem to have the same problem. It is not clear if there was a BIOS problem (virtualization, which emulator uses, is a BIOS option) or if it was just the reboot which temporarily cleared up memory (my original guess).

Starting AVD Emulator always gives "Android Emulator Closed unexpectedly"

My sincere thanks for your reading this.
I have just installed Android Studio and am attempting to run the default Hello World! script that is present when you create a new project.
Every time I try to run the the program in an Android Emulator my Emulator crashes and I get the error "Android Emulator Closed Unexpectedly" Every. Single. Time.
I have the Intel x86 Emulator Accelerator (HAXM installer) installed as suggested:
I try to run a Nexus 4 emulator with 512 mb of Ram and it never works:
When I run this I get:
During this, my system physical memory peaks at 80% but never goes to 100 (which I would expect if it were crashing).
I have searched similar questions including
Android emulator crashing on Windows 7 64 Bit Android 4.0 emulator always has a crashing Launcher? Android studio emulator fails to start with memory limit related error message and they say to lower the memory size (which is what I am trying to do). Unfortunately this isn't working
Any idea how I can solve this issue?
My computer specs are as follows:
64 Bit Windows
6gb Ram
Intel Core i3
I downloaded and installed all correct versions as instructed here: https://developer.android.com/studio/install.html

In my case, this issue took the whole weekend to solve.
All options I tried, until:
Android Development Studio prompted me to update the Android Emulator Version to 25.3.1 (no idea what it was on before as I didn't check this before). This was a download of ~170mb.
Once I downloaded and installed the update, the emulator now seems to run OK on low memory settings - settings in keeping with the answer to this question here: Android emulator generates a very annoying error
I am now running with settings:
RAM memory to 5012
Virtual heap 32
Internal storage 200 mb
External storage 64 mb
So basically, it was a complete fluke that this worked.

To anyone that gets this error after rooting the android image, (if using snapshots). You need to start the virtual device with the -writable-system parameter like when you rooted the device, excerpt from docs.
Snapshots
...Starting a virtual device by loading a snapshot is much like waking a physical from a sleep state, as opposed to booting it from a powered-off state.

I was also having the same problem, Every time I was starting Emulator, it was closing unexpectedly. then I tried to change the Emulator Performance in settings of AVD Managers; In Software it's not working but in Hardware it was showing blank black screen.
Then I realized, there might be some issue with Graphics Card(mine NVIDIA GeForce 940MX), It was showing this error
After Updating/Restarting the problem was not resolving, then I Disabled then Enabled the Graphics Card Driver in the Device Manager and It worked!!😊
LONG STORY SHORT: Check, the problem might be due to your Graphics Card!😐

in my case, i attempted using gennymotion [ you may install it asking google genymotion . com] this could serve as alternative.
if gennymotion after installation returns this error message "the version of openGl supported by your graphics card is too old:Genymotion requires at least openGl 2.0 support. "
then know our challenge is arising from not having required graphics driver
either you checkout this link [https://buffered.com/support/solve-opengl-error/] on how to resolve it in steps.
or you download the graphics drivers using the links below
Here are the links to the 4 most prominent graphics card manufacturers in the world:
Intel: http://www.intel.com/content/www/us/en/support/detect.html
restart your systems after installation of the appropriate graphics driver and continue your project .

Android Emulator startup time is too long

I am using Android Studio with Intel HAXM. The problem is that the Android emulator takes too long to load and once it is loaded it is slow despite the Intel HAXM installation.
I just referred this question and below were my results
Android Studio startup is taking long
Result: The emulator is still slow even after loading it for a couple of times.
Intel HAXM configuration
Memory allocated: 1.9 GB(this is the max size as specified during the installation)
Status: Intel HAXM is working.
Android Studio
AVD Details
API Level:19
Android Version: 4.4.2
Please see the screenshot
System Configuration
Core i3 2nd gen
4 GB RAM
Please let me know if further details are needed.

I had the similar problem to you in the past, but its just down to your processor (i3) as it cant handle the emulator that well, you can debug/run your app on to an android phone or tablet. If you have either of these to hand you need to go to RUN ---> EDIT CONFIGURATIONS and change the target devices to 'USB device'. On the phone/ tablet you need to go in to developer options and turn on USB debugging, if this doesn't work check to see if you have the phones/tablets drivers installed. There are plenty of tutorials on youtube. Good Luck! :)

Android 4.0.3 not getting boot in AVD

I'm newbee to Android. I have set up all things in the android site to run Hello world program. I've installed the latest platform Android 4.0.3.. I've created an AVD and when I tried to start the avd, a screen showing ANDROID runs. I've been waiting for more than 2 hours to get the menu in the avd, but nothing worked up.. Can anyone help me out to find the problem??
[Note: I'm using Pentium 4 processor running in windows XP]

you must have install X86 atom emulator...
which requires haxm(hardware accelerated execution manager) which requires intel vt supported processors, and pentium 4 does not support virtual technology.
so either try using another emulator or change your processor.....
check installation instruction for haxm here
and check your processor capabilty here

4.0.3 usually takes a long time to boot for me as well, running on 4 GB RAM on Core i5. I would recommend working with a lower version such as 2.3.3 (which mobiles support as well). But here are a few general steps to make avd run faster (assuming you are using Eclipse):
Run > Run Configurations > Target. Check the "disable boot animations" and in the additional options, specify "-scale 0.5".
Enable snapshots. This allows you to save the running emulator and instantly load it at a later time (so you only have to boot up once).
Go to AVD editor and edit the AVD. Check the "Snapshot Enabled" check box.

Well just restart your eclipse. If the praoblem persists then check if you have provided any virtual sdcard file with right permission.
