My Android Studio emulator is not working correctly

I downloaded the Pixel emulator and Android API 25, but when running it
appears for a few seconds and then disappears
In the Event Log, this is what appears
I need help pls

The same Problem got me a few months ago:
I fixed it by doing this:
Whenever you run the project or app you have to clear the data of that AVD
To wipe the data of Emulator follow these steps-
Go To AVD Manager then you will see all emulators there then simply wipe data. ie- like in this image shown.
step 1
step 2
step 3

I also had random emulator crashes, everything would work for a short while, but then the emulator would just disappear as if it had stopped. The emulator.exe would still be running task manager, no way to recover the window and the .lock file couldn't be removed.
Even just starting the emulator and swiping the home screen left and right (not even starting my app), or going into the the apps drawer and back would cause the the emulator to stop working properly.
What worked for me was to always start Android Studio as "Run as administrator". So right click on the startmenu shortcut and select Run as administrator.
Not sure why it randomly stops working otherwise, I'm sure the Android Studio QA team thoroughly tests this on real-world laptops outside of Google labs right...? /s

Android Studio- ADV "System UI isn't responding"

So I'm a beginner in Android Studio. I have created a Nexus S as an ADV. Every time I launch that device, it says "System UI isn't responding". I get 2 options; close app, wait.
When I click close, nothing happens but when I click wait, it just goes on as if nothing happened.
I was just wondering what I can do to get rid of this problem?
Also does increasing the RAM on the device make it any faster? Can I do anything to make it faster?
Thanks

This caused because of the RAM size is small in my case.
Open AVD Manager
Select the device > Show Advanced Settings > Change the RAM.
If you can't edit the setting, then create new device.

The system ui isn't responding in android emulator (Flutter)

I used to face this problem every time I started my AVD. Also the cold boot option was just a temporary fix for me.
I checked the android version that I had installed on my emulator, and noticed the ABI version was x86.
I downloaded the X86_64 version and I have not faced that error again.

android's hello world tutorial application is not working

I am new to java and android and wanted to see how developing for android works
I started by downloading the SDK FROM HERE
However after I finish making the Hello World project sample given in the website HERE, if I try to run it on the emulator as explained HERE, the emulator screen appears, but nothing seems to happen. I can see the word android on the middle of the screen with some animation happening, but that's it. The website says something about unlocking the emulator, but I have no idea what that means. What I have gathered from reading other posts is that the emulator is supposed to have some kind of slider switch as in real smart phones which should be dragged to unlock it, but I can't see it in my case. Now I have no idea why this is happening or what I should check out in order to fix this. Are there any installation logs or something else that I can check to see what the settings are?
What I have tried till now:
I downloaded the SDK ADT bundle from HERE and just unzipped it. Then looked for eclipse.exe and ran it directly. Is there anything else I should have done prior to this?
When I did it for the first time, I had only JRE installed and not JDK, which I realized after reading THIS POST. So I downloaded JDK from HERE, updated the required environment variables and restarted eclipse, but still it's the same thing.
I looked at the Eclipse isn't talking to the emulator section GIVEN HERE, but all it says is to restart eclipse and the emulator, and it doesn't do anything at all.
Rant:
I can understand if the program had failed to compile when I didn't have JDK , or if the IDE gave any indication at all of a faulty program install, but that isn't the case. Everything seems ok, there are no errors, but it just doesn't do anything. This is the type of thing that makes people pull their hair out, and personally, I think the With a single download, the ADT Bundle includes everything you need to begin developing apps: in the android website is very misleading, especially for complete beginners
Anyway, what should I do to make the tutorial program run on my computer? My computer is a bit old and slow so could that be an issue? My computer is Windows XP SP3 on Intel(R) Pentium(4) 4 CPU 3.20 GHz 3.19GHz 2.50GB RAM, but if that was the case I assume the emulator shouldn't even start up

You just have to wait a bit longer. Android loads pretty long on emulator.
Tutorial says about unlocking, because when Android is loaded, your screen on emulator will be locked.
If you find emulator too slow for you, you may want to check this topic out: Why is the Android emulator so slow? How can we speed up the Android emulator?

I had the exact same problem as you when I first got into Android development a week ago. The two things I did are simply
1) Set the usable RAM on your AVD to 768MB
2) When you run your Hello World program in your emulator, give it about 5-10 minutes. Don't touch or click the window at all, just let it load up. Later you can make it persist
3) If your home screen comes up, click and hold the mouse button in the center of the screen, then drag towards the sides and release, this should unlock the device.
Try these steps first, if they don't work then there is likely a problem with your AVD configuration.

If you are launching your app first time with emulator, it will take appropriate time.After that, on Lock icon click and slide to the right. then you can view you application. If not check for your app(icon) installed.

By seeing your configuration of PC I think it will take some time to load emulator. After emulator is load (see below image)
then and then run your code and also check in eclise-device that whether emulator is online or not.
For checking emulator in eclispe :
In second image just above windows logo you can see small rectangular button with plus sign click on that you will get list from which you can select devices. You can find similar button in you eclipse at the bottom.

I had the exact same problem and followed the exact same steps, but was also unsuccessful. I ended up creating a new AVD with a Nexus 4 instead of the latest Nexus 6. The resolution of the 4 is much lower, which I think is what solved my problem. It loaded much more quickly using the 4.
Also, When I was using the 6, I could only see "ndroi" because the size of the screen was much larger than the size of the phone. Now I can see the full device.
vs.

You may just need to relaunch the Android studio 3.6.3.
I got a similar problem. The hello world app does not install on the emulator.
Problem solved after relaunch.

The emulator runs slow [duplicate]

Making the Android emulator run faster
(19 answers)
Closed 7 years ago.
Recently I started to learn Android programming. I instaled Eclipse and Android SDK. All goes well, but every time when I run a project which has a error, the emulator and Eclipse begins to run very hard and I often have to close Eclips and the emulator.How can I solve this problem?

I answered this before, but it might help you too.
I prefere using the the Bluestacks Player. It runs Android 2.3.4 and is very fluent and fast. Sometimes even faster than a normal device. The only downsize is, that you can just test Apps on the API Level 10 and just on one screen size, but it's perfect just for testing if it's working or not. Just connect the Player with the adb by running
adb connect 127.0.0.1
After compiling it installs instantly. Very impressive, considering I have a rather average computer hardware(dual core with 4 GB of RAM)

Here are my suggestions:
Do a quick google search for "how to make the Android emulator run faster" (or something along those lines), because you are definitely not the first person to ask this question.
Buy a cheap, physical device to test with. It'll make your life a lot easier.

You don't have to close the emulator in order to iterate your development cycle. That should speed things up a lot for you. You can also enable emulator snapshots, so the emulator will start up quickly the next time. (It does slow down closing the emulator, however).
The other thing is, though, if your machine is underpowered or does not have sufficient RAM, it could be thrashing. Eclipse and the Android emulator do require a fair amount of memory. Ideally, you should have at least 500MB of free memory before starting Eclipse (1GB would be better).

In my experience, when you always install and re-install apps on the emulator to test, it gets clogged up and starts lagging.
Solution: Delete the AVD you have created from the Virtual Device Manager.

I hope this will help you.
Goto to your BIOS settings. Enable your Virtualization technology in your settings..
It solved my problem...

Eclipse was working fine this morning... Now it and the AVD crash every few minutes?

I was using Eclipse this morning and it was working fine, both it and the AVD would load in less than a minute... After a few hours it started crashing.
Now if I'm lucky enough for Eclipse to load without crashing the AVD takes at least half an hour to go from the basic "ANDROID" text to the actual logo.
I've tried cleaning my project, recreating the AVD, increasing the AVD's memory from 256mB to 1024, disabling animations and loading from snapshots...
Other than using Eclipse the only thing I have done with my computer is searching on stackoverflow.
What could have caused such a change in performance over a few hours?

Maybe you started a background application or something. Restart your machine. Your memory is probably being barraged somewhere. Check that the processor isn't on battery save mode or anything.
Also, perhaps this post might help.
