I have a Windows 11 machine, with a RTX 3050 graphics card. It's a Dell G15 laptop. I cannot find a (good) solution to the graphical glitches that appears on an Android Emulator.
The only "solution" I found was to change the hw.gpu.mode in the config.ini file from auto to guest. That fixes the glitches, but causes really bad performance issues and one app I developed with Flutter for my company straight up doesn't load. (loads when hw.gpu.mode=auto).
I'd appreciate if you can point me to the right direction to solving this. Let me know if you need any other details about my machine:
OS: Windows 11 Home Single Language [64-bit]
Kernel: 10.0.22000.0
CPU: 11th Gen Intel(R) Core(TM) i5-11260H # 2.60GHz
GPU: NVIDIA GeForce RTX 3050 Laptop GPU
Nvidia driver version: 516.94 (Downloaded the "Game ready driver" from GeForce Experience)
This problem is only on emulators with android 12+, personally i installed a device with android 11 and a second device with android13 for tests.
It seems like dedicated Nvidia GPU's are causing the problem. I have a 3060 laptop and I have the same issue and when I set it to guest it seems to work. My guess is that setting changes it from using the GPU to the CPU. I would recommend you try setting android studio to use integrated graphics instead of dedicated. Since I have a 8 core CPU compared to a 4 core CPU of yours, I'm guessing that's the reason I don't get as bad performance
I'm using Visual Studio 2019 on my Laptop that is connected to an external monitor. Both my laptop and the external monitor have a 4k resolution.
I'm facing a weird performance issue, where after every click/right-click the whole UI freezes for a couple of seconds. For eg. if I right click on a project, the UI completely freezes, not even the mouse moves and after 1-2 seconds I see the context menu.
My laptop is new and this happens only with VS 2019 and only when my laptop is connected to an external 4k monitor.
Anyone else faced a similar problem or knows a solution for this?
My Laptop has the following configuration:
Intel i7-10750H 2.60GHz
16GB RAM
SK Hynix PC601 M.2 SSD
GTX 1650 Ti Graphics Card
After a little digging, I found these options in Visual Studio. Turning them off seemed to do the trick:
Tools > Options and then under Environment > General deselect the following options:
Automatically adjust visual experience based on client performance
Use hardware graphics acceleration if available
If you want to go one step further, you could also disable the following option along with those above. (but in my case, just disabling those two seemed to suffice)
Enable rich client visual experience
Here's the GPU usage before and after disabling the options (for similar UI inputs).
Before:
After:
In the Before picture, the duration for which the GPU 3D usage remained consistently high is when the UI froze.
What I still don't seem to understand is why VS would need so much of GPU 3D computational power.
I have an Acer Aspire E5-573 laptop with 4Gb RAM, Windows-10 64 bit operating system. Whenever I start my Android Studio, my laptop stops responding, and I am my program does not run on the emulator. What do you think would be the problem?
You have to increase your RAM atleast 8gb,
alternative way:
Use lower version of android studio because version 4.0 and up has many features like animations etc. don't use AVD Android Virtual Device instead try to use Physical phone as emulator
Its mainly happen when your computers memory (RAM) run out, when there is no sufficient memory(RAM) space left to run your program than your laptop is not responding.
Possible solution
Increase your RAM (memory) to minimum 8 GB and
Include a SSD storage in your laptop
Actually in this case all system is quite slow but the emulator is extremely slow.
Hardware acceleration is enabled, emulator works just fine if I close Android Studio.
The OS is Ubuntu 18.04
Any ideas how to fix this?
P.S. I did read all recommendations regarding emulator performance and it works fine until I start Android Studio.
Go to Tools > AVD Manager > Edit a specific Device > show Advanced Settings >
1. reduce RAM
2. Make sure your using Quick Boot
3. Enable Multi-Core CPU
For me it was completely different I was getting some data from a node server which I forgot to start. The php was delivering the date so could not see the problem on UI. Just started the node server and it was fixed.
Check all server side starts.
In my case (Ubuntu 20.04, Nvidia GPU) it was hardware rendering not being auto-enabled, so I had to manually enable. After that the emulator was very smooth.
Device Manager > find your device > Edit > Emulated Performance / Graphics > Hardware - GLES 2.0
The emulator qemu-system-i386.exe cpu usage almost constantly running between 7~9
Android studio 2.1
Android SDK Tools: 25.1.3
Host Operating System: Windows 7 - i7 2630QM - 8GB Ram
Intel x86 Atom System Image installed
No matter what setting i change in the emulator like: emulated performance, multi-core CPU, x86-64 image, always the same thing
It is really annoying fan always on
Anyone had a fix for this issue?
The cause of the constant CPU usage could be the sound. If you do not need sound in your emulator you can disable it by editing the AVD's config file.
Change/add those two lines
hw.audioInput=no
hw.audioOutput=no
Update: As buncis commented you can also try to disable GPS if not needed:
hw.GPS = no
On Linux/Mac the file is located at ~/.android/avd/<AVD_Name>.avd/config.ini
On Windows the file is located at C:\Users\<username>\.android\avd\<AVD_Name>.avd\config.ini
On Mac I noticed that the emulator was using over 100% CPU after my laptop went to sleep. Turning the audio off as Benjamin suggested didn't fix that problem.
Restarting the simulated device by long-pressing the power button on the emulator works for me.
Using the x86_64 (Or the 64 bit) emulator solved it for me. They recommend the x86 version, but it was acting up for me.
To find out what on the virtual device is using the most CPU:
adb shell
$ top
This will show you a list of processes with the highest CPU usage atop.
This will help you determine whether it's a process (such as your app) inside the emulator, another process inside the emulator, or just the emulation itself using a lot of CPU.
In the latter case, try optimizing the emulator by installing HAX (Native intel instructions) or perhaps enable hardware acceleration using the AVD profile editor.
I had that problem on the start of November 2018.
Virtual device was contently trying to connect to the mobile network data, so I turned it off inside of the device itself.
Work great now.
The same problem with qemu on Win7, HAXM 7.2.0. I've tried switch off audio, it didn't help, qemu consumes about 20% of CPU anytime, Android works very slow on both x86 and x64 images.
I've found solutions in HAXM's Release Notes file:
On Windows, Avast Antivirus may interfere with HAXM and cause Android Emulator or QEMU to run very slowly. A workaround is to uncheck "Use nested virtualization where available" in Avast Settings > Troubleshooting.
I have Avast Pro Antivirus 18.5. I've unchecked this param, rebooted PC and now qemu consumes 0% in idle, Android works fine.
UPDATE: if QEMU started consume CPU again, first check Avast's update status. After background update Avast may start to interfere to HAXM again. Just reboot Windows to solve it.
In my case using hardware graphic solved my problem.
my case, coz I choose software for graphics rendering in adv. so after a change to the hardware reduce CPU usage from 60 to 10, and CPU temp from 70 to 40.
I am on macOS Catalina(Version 10.15.2) with Intel Core i9 and 16 GB RAM and Radeon Pro 560X 4GB Graphics.
I solved high CPU usage by qemu by restarting the emulated device using the emulated power button.
Also, while creating the AVD, I chose Hardware Graphics Renderer instead of Auto.
Using kind of old Android version I used Lollipop Galaxy Nexus API 22 dropped CPU usage from 220% to around 30% ! ...
I also switched: Emulated Performance > Graphics > Hardware
Using Android Api 25 ... Hardware for graphics and turning off AVD audio and GPS didn't work for me...
Platform: MacOS
I reduced the CPU usage of my emulator by setting the framerate of the monitor to 60hz. It was on 144hz and my CPU was running at 60% - 70%. By only changing the framerate of the monitor, it's now sitting at 3% usage.
I wasn't able to shut the audio off with the config.ini file, but only with the -noaudio cmd line argument to qemu. However, with Android Studio 3.2, you can't add custom arguments to the emulator, so I made this:
In the emulator dir of the Android SDK, in my case ~/Android/Sdk/emulator/
mv emulator emulator.orig
Make a bash script called emulator with the content:
#!/bin/bash
DIR=`dirname "$0"`
$DIR/emulator.orig -noaudio $*
Then:
chmod +x emulator
Now, the argument -noaudio will be added to all invocations of emulator from Android Studio and will save you a lot of CPU cycles.
I solved it by cancelling "Auto-save current state to Quickboot"
Snapshots -> Settings -> Auto-save current state to Quickboot - NO
I had the same issue recently on Windows 10 (18363): the AVD used all of the host's 16 Threads at 100%, it seems the android.hardware.graphics.composer#2.1-service process on the AVD was to blame.
What helped in my case: going to AVD settings - Advanced - change the OpenGL ES renderer to Desktop native OpenGL and restart the AVD. Now it uses like 2-3% of my CPU resources. Hope this helps someone.
Update:
I have installed Genymotion plugin at genymotion.com/plugins, and it has an amazing performance
In my case, I only encountered this issue when running multiple instances of the emulator.
Re-run the Intel Hardware Accelerated Execution Manager (HAXM) installer provided in the Android SDK (<Android SDK path>\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm-android.exe), select Change, and see how much memory is allocated to HAXM. If it's 2 GB or less, you probably want to raise it to at least 4 GB. Then restart your emulator and see if the CPU usage drops.
Disable location in settings and also disable touch sounds.
In my case it was the fast boot that was causing the problem, to force into normal boot open the text file in C:\Users\<username>\.android\avd\<AVD name>\config.ini and change at least one of the values.
for example change the line
hw.battery=yes
to
hw.battery=no
In my case it was Airplane mode, when turned ON the CPU usage jumped to 99%:
adb shell
$ top
The issue was noticed on Android 10.0 x86.
If you turn Airplane Mode OFF then the CPU usage should return to normal.
Changing the resolution worked form me. I was using 1440 x 2560 560 dpi Oreo 8.1. Now im using M-DPI Oreo 8.1
For me I turned WIFI off and I dropped from 112% usage to 10%. I would recommend doing this
Just do
$adb shell
$top
Look the PID which high CPU
$kill -9 <PID>
on api31&32: do EDIT each AVD config with Show Advanced Settings and be sure to:
Multi-Core CPU > max (<=> hw.cpu.ncore=8,
4/cores is not enough and may overheat cpu strongly)
Graphics > Hardware (GLES 2.0)
No-SDCard (<=> hw.sdCard=no)
