On a Windows 10 machine, I'm trying to use emulators for Android development but run into the problem that the emulators do not show any characters:
This happens for all emulator types. The one showing in the screenshot is a Pixel 2 device. I have performed a reinstall of the video drivers, the emulator part of the Android SDK and the HAXM driver, but no success so far.
Are there more persons encountering this?
Ok, just found the cause of the problem:
Setting both options in this emulator settings screen to 'autodetect' & 'autoselect', and restarting the emulator solved the issue.

i'm using android studio in windows server 2016 and have next problem: for work task i need to start android device emulation. On windows 10 emulator works fine, but same steps on windows server cause problem -"the emulator process for AVD_Pixel3A was killed". What should i do?
p.s: hyper-V components not installed, virtualization is accessable.
You will need to to have the H-visuals turned on.. Also check to see that you have HAX installed. Also be sure to turn on developer mode within the computer... I would also run the program on a physical android device to see if you get the same issue.
Also if none of these work you might have to check to see if the server runs the minimum requirements. If it does you may have to reinstall Android Studio. I had this happened to me the other day. I uninstalled and reinstalled Android Studio and it fixed the issue.
Suddenly my Android Emulator stopped working and it shows only black screen. I tried ADB devices with cmd and it says device offline. My Android Stuido version 4.0 . Intel HAXM version 7.5.6 . Android Emulator version 30.0.12 . I also tried this command in cmd --> "emulator -avd Pixel_3a_API_28 -gpu host". then it says " emulator: INFO: QtLogger.cpp:68: Critical: UpdateLayeredWindowIndirect failed for ptDst=(1429, 210), size=(300x21), dirty=(300x21 0, 0) (A device attached to the system is not functioning.) ((null):0, (null)) ". I also tried changing quick boot to cold boot in virtual device verify configuration. Tried changing android system image to lolipop, marshmallow. Tried changing avd device to pixel, nexus, generic devices and tablets. Non of them worked. Is there anyone who can give me a solution for the problem? My device has seperate VGA(GTX 1050ti). Windows version Windows 10 V2004.
The Emulator has a lot of problems since the last update. I got the same problem and I tried to solve it in many ways , and it worked suddenly and stopped working 2 days later.
Until they make it work properly I advise you use Genymotion or a regular phone.
Same problem had happened with me ....In my case the problem was about selection of wrong system image file .I had installed R (Api level 30) x86 for my emulator but it starts giving me problems so instead i installed R(Api Level 30)x86_64 for my emulator and fixed all . Make sure you install x86_64 system image file and give a try
I have tried almost all the ways to rectify this error but nothing happened. I am running a Windows 10 Home Single Language machine and on googling it shows that hyper-v is only a feature of windows 10 pro.
Then how can I get such a error ?!!??
The emulator was running fine for the last few days. Only today has this problem arised.
Even Hyper-v is not showing up in the windows features on or off list.
Even on disabling and rebooting the problem is not solved.
I just want to run the emulator since I am an Android developer.Please provide to the point help and workarounds.
Thanks.
Screenshot added for reference.
Error
I am facing this problem when i am starting my emulator from android studio avd manager. it shows the list of my virtual devices. now when i start the emulator. it shows progress to opens and disappeared in a second without throwing/showing any error.
i am using latest android studio version.
system config : Intel core 2 duo
ram : 6 GB
is this problem cause of system config? Please write your answer and feel free to ask.
I had similar issues (the simulator progress would open then disappear) on my Mac El Capital. Downloading the latest HAXM and RE-INSTALLING it fixed.

I have updated the video drivers and solved :
1. emulator problem
2. genymotion "player.exe stopped working" problem.
You should use Genymotion replace for default Android Emulator.
There are some various ways to solve this kind of problems:
-> after restarting android studio, if u are facing same problem then try below ones.
kill the adb server through adb shell and then start adb and then launch your emulator.
2.First uncheck Enable ADB Integration and launch emulator and then check Enable ADB Integration.
3.launch your adb and emulator by Debug app from run .
4.maintain the targetSdkVersion corresponding to your emulator
5.uninstall existing emulators and create new one.
delete your adb application and and download new one.
I had this problem because I had many (20) devices saved in my AVD with lots of memory allocated to each (1GB) and my laptop was lower than normal on memory itself.
I cleared out the devices in AVD and started over and it began to work normally again.
I'm just new with Android Development, and running the default blank project. I have Android Studio 2.1.2.
The problem is the emulator stuck with the black screen although HAXM works well:
"HAX is working and emulator runs in fast virt mode"
Most solutions suggest to uncheck "use host gpu" in AVD Manager, yet it seems this feature no longer appear in the new version of Android Studio.
I run macOS El Capitan.
After an update to Android Studio this weekend (maybe Gradle?), the AVD emulator (Mac) suddenly started showing a black screen when I ran my installed app APK. Sometimes it showed a blue screen. Sometimes the emulator even showed a page of installed app icons. Sometimes upside down. Sometimes upside down and reversed! That smelled like a graphics problem.
Thanks to audio in my app, I realized I could still activate buttons in my app by clicking on a specific location of the black screen. Definitely a graphics problem.
Based on other ideas that I read, I edited my AVD device config in the Emulated Performance section, to change Graphics from "Automatic" to "Software - GLES 2.0".
It worked for me on the emulators for Nexus 9 and Pixel XL on API 25.
This solution does not work on Play Store-enabled devices because the Graphics setting can't be changed. For example the Nexus 5X API 25.
Environment: Android Studio 3.0.1, Gradle 4.1
Increase the RAM size to 2.5GB in Advance settings of Emulator. Black Screen will be gone.
It worked for me
The reason why I got stuck with black screen in the emulator is that I needed to update my Android SDK Tools. Hope this could help someone get the same issue.
I believe the emulator was updated in studio 2.1.3, can you update and see if you have the exact problem?

Selecting CPU/ABI with Intel Atom(x86_64) (when creat a emulator or editing a emulator) worked for me.
