I have just installed Android Studio to follow a react native project and everytime I try to use the program the disk usage goes to 100%.
I've chosen Pixel 2 as the phone and android Q and R as the versions.
The program works well until I click the "play" button to start emulating the android OS.
Then the phone image starts loading the android OS but it's just too slow to do anything with the emulated phone.
I have tried reinstalling the program.
I have tried disabling firewall and windows defender.
I have tried using different versions of android ex.: Q and R.
I have 8GB of RAM
HD of 465GB
Intel Core i3-4150 #3.50GHz
GeForce GTX 750 Ti 2gb
I also tried to increase memory size for android studio on file studio.vmoptions.
From this
-Xms128m
-Xmx800m
To this
-Xms256m
-Xmx1024m
I have also created a gradle.properties file with
org.gradle.daemon=true as I saw in another question but none of the things above worked.
I have no more clue on what else I could do.
Your emulator required big memory to launch it and as per your PC configuration so you build an emulator for N and use pixel phone not pixel 2 okay.
hopefully, they resolve your issue.
Disk Usage on Task Manager is not the volume of disk being used.
It is fraction of speed of data transfer from your Disk to RAM.
Usually Hard Disk has lower Read/Write speeds and act as bottleneck for the performance of PC. There is no problem with your Android Studio or any other software. Any Software that requires a lot of Read/Write operations on your Disk will show 100% Disk Usage. You cannot do anything with that.
Unless you replace your computer Hard Disk Drive(HDD) with Solid State Drive(SSD). Because Solid State Drives has very high Read/Write Speed than Hard Disk Drives.
For Now you can use your Android Device for testing rather using an emulator, it will save your computer resources used by emulator.
I know this answer will not help you right now. But this is the correct answer and reality. Go Checkout the Difference between HDD and SSD in Google.

This is not a rant, and also not a duplicate of the forever "why is Android emulator so slow" problem. So, until a few weeks (maybe months) ago, emulating Android devices on my Win7 64-bit system was at the very least acceptable (x86 emulation was decently fast to be usable). However, trying to create any ("fast" "new" "2.0") emulator instances using the latest version of the SDK, platform tools, etc., is only a source of frustration and pain for several days now. I'm trying to understand if it's an issue on my side or people can actually use the latest version of the Android emulator included in the latest SDK, on Windows 7.
My PC config: Win7 x64 / Intel Core 2 Quad #3.8 GHz / 6 GB RAM / plenty of HDD space / dedicated GPU
What happens when trying to start an emulator with any API level, with either x86 or x86_64:
version 1) emulator starts, Android logo appears, glows for a bit, and that's it. It never reaches the Home screen. Emulator log shows absolutely no errors. Trying to connect using adb freezes Android Studio until I kill the emulator process.
version 2) Same like version 1, but in this case I can't even kill the qemu-system-i386 process (yes, not even with full admin rights). I have to actually restart Windows. Process remains a zombie, using 1 GB of RAM.
version 3) If I'm lucky, sometimes it reaches the Home screen, but becomes completely unusable. Sometimes I can click on things (maybe 2-3 clicks), and then becomes completely unresponsive. Occasional "Launcher has stopped" / "System has stopped" messages appear randomly in the emulator's home screen...
I've installed the latest Intel HAXM 6.0.3 version (the one downloaded by the Android SDK manager). Virtualization is enabled in BIOS.
I've tried all kinds of emulator options (more or less RAM, hardware vs software GPU, x86 / x86_64). Almost same result every time.
I've completely deleted and reinstalled the entire Android SDK and Android Studio.
CPU is not the issue - it's not under load while emulator runs.
Free RAM is not the issue - it's not fully used while emulator runs,
HDD is not the issue - I even defragmented it, and it's not looking like it's under any sort of load while emulator is running.
So, my question is very simple: is anyone out there using Windows 7, who can actually start up, let's say, a Marshmallow x86 emulator just by a simple 2-3 clicks process, and actually have it reach the home screen? Or does the "new, faster" emulator actually need some sort of super-powerful machine which I don't seem to possess anymore? The only thing that apparently changed was the HAXM driver. But it's stating that it has initialized just fine, so I don't know. Oh, and VirtualBox runs just fine. GenyMotion, by contrast, just flies. But I'd like to have the official Android emulator in a working state, or am I asking for too much?
Adrian, in my sad opinion: yes, you would need a powerfull processor, even a litle bit more of ram. The almost-aceptable scenario for you to run api 24 emulation in xxxhdpi resolution is an i7 with 8 of ram.
But this is what hard and software manufacturers want you for: upgrade, upgrade, upgrade. And it's not necessairilly true for you, or not obligatory for today. Maybe tomorrow...
It's my case too. I have a second generation i5 with 6 of ram and plenty of disk. Have a good geforce gpu too. And what I do to have my emulators running, or, how do I emulate in my win7? First of all: unninstalled all the last (about 30) non-security system updates from windows (! yes..., they make your system very heavy, the same with the various distributed c++ packages microsoft want us to carry on with our systems even if we use it once a year, or less - go to control panel and ripp'em off! Keep only the most recent c++ package - if you need it later, update again). Actually I'm even investigating what else "updates" I can delete from my system to have it usable again, mine again. Microsoft...
Second: enabling "power save mode" on your android studio (menu file), only in testing times, seems to make things faster.
Third: do heavy tests on emulators with "low" apis, like android 4 or 5 at max. And emulate devices with small screens or resolution, 5 pol. with 720 points (hor.), at max. If possible use _x86 64 emulation.
With this you can make it happen. The emulator is slow to load and open, but when running it works in a fairly good speed. First thing to do there: enter developer options and "force gpu" on both places. This will instruct your pc to take advantage of your dedicated gpu system.
Do not try to open two or more emulators at the same time, sorry.
When 90% of your debug is done (i do it in an emulator running android version lower than 5, normally 4.0 or 4.1 - 480x800 screen), then you pay the price to load a big screen, big dpi android 5, 6 or N). While it loads, make a coffee and use the bath.
When the beauty (beast?) is loaded, then do the final tests with all your apps that stayed waiting for this special moment. I maintain all my apps waiting for it. When I load the "big" emu I use this oportunity to do all tests I was needing - because it's not a simple task open this everytime I want.
In the future, as said: i7, 8ram, powerfull gpu and, very important: a good SSD drive (until 10x faster) to throw up damn nasty harddisk to the garbage. :) Best.
EDIT: when you create an AVD image with the latests APIs, Android Studio defines the ram and disk space values for the emulation and, in my opinions, these values are too big and too hard for the hostage computer to deal with. First point: your testing app never will demand all those resources. Two: your pc suffers hard to deal with a very fragmented Gb data from here to there, and there to here. Three: the virtual image created on your hard disk gets bigger with the use. So: 1 - lower the default values from your avd images, ram and disk sizes; 2 - on the avd launching window dialog, edit the options of each image and rip information everytime before start the emulation OR/AND 3 - uninstall your apps from the emu when not needed.
To increase performance, I want to allocate 1024 MB RAM to a tablet emulator. Problem is that it won't start, i.e. no windows/consoles show up when I click Start in the Virtual Device Manager. If I let the device to its default 256 MB, it starts. How can I fix this?
I'm using Windows 7 Ultimate with Intel i7-2.2 GHz and 8 GB RAM DDR3. It used to work fine on 32-bit windows.
I know this isn't an answer to the particular question you have asked, but it may help with the underlying issue: you can increase the performance of your emulated device by switching to an x86 version.
The Android emulator has always been painfully slow for me, even on a quad core rig with 8 gigs of RAM, so I started following the Android x86 project. Not long ago, I finally took the plunge into getting it set up, and it was easier than I expected--and it's really, really fast.
If you have VirtualBox installed, all you have to do is download eeepc.iso from the project's website (for whichever Android version you prefer), create a VM for it in VirtualBox with however much RAM you want it to have, and boot it up. Pick VESA mode from the menu, disable mouse integration on the VM, and skip the google account login process. You'll be good to go.
Then just set up port forwarding for ADB from guest:5555 to localhost:whatever-port-you-choose, and point ADB at localhost:whatever-port-you-choose, and it'll work even better than the ARM emulator that ships with the SDK.
I disabled the camera support and I was able to use 1024MB of RAM.
So, like a lot of people starting Android development with Eclipse, even with a fast machine, I notice that the emulator runs frustratingly slow.
I search SO for any tips to make it run faster and I run across this question, whose top answer suggests a couple of things, including making the AVD have more RAM. They suggest 1024MB:
Sounds good. But when I try to launch it, I get this:
Failed to allocate memory: 8
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
If I set it to 512MB (up from the default 256MB) it launches fine.
But why, on a Windows 7 x64 machine with 12GB of physical RAM can I not allocate 1024MB to an AVD? Is it an Eclipse limitation? Emulator limitation? Java limitation? I presume the person in that other question got it working but I've yet to figure out how and most of the responses I see elsewhere say "yeah dial it down to 512MB" which is not the answer I'm looking for.
From Galaxy s3 emulator:
There is a common problem when setting up the AVD that you have to manually edit the config file to fix. File is located at C:\Documents and Settings\username\.android\avd\name_of_avd.avd\config.ini
Change the memory settings from
hw.ramSize=1024
to
hw.ramSize=1024MB
(Do not enable word wrap in notepad).
Save the file and reopen the avd.
This worked for me.
Weird, but this worked for me on Windows 7 x64 machine with 16GB of RAM. You do have to add MB at the end of "hw.ramSize" in config.ini.
I had the same problem like OP wrote. Also, if you need 2 gigabytes of RAM, write 2048MB and simulator will run from Eclipse.
I have the same problem occasionally, and I'm unable to tell you exactly why this problem occurs, but it seems that the AVD won't start if it has been allocated more then an X percentage of your available RAM at the time of starting.
If you lower the given amount by just 50mb, you'll often notice it will run just fine. Or, similarly, if you close a few programs to save some RAM, it will also boot up perfectly fine.
I know it's not ideal, but I suggest to just lower the allocated RAM in small amounts until it boots up. I wish I could give a better answer but I haven't been able to find a reason myself either.
Try starting the AVD without Eclipse to remove that Factor.
This can be done by navigating to your SDK-Path/tools and open Android(.bat?) and then select the AVD manager.
I would recommend opening a command shell, navigating to the path and then run
emulator -avd AVDNAME -scale 0.7 -no-boot-anim
You can also try starting it without the scale parameter or maybe even a lower number.
On Windows, emulating RAM greater than 768 may fail depending on the system load
Open C:\Users\your user.android\avd\yourAVD.avd\config.ini
change
hw.ramSize=1024
to
hw.ramSize=1024M
this worked for me :-)
hope it will help!
I'm beginner on Android applications. I followed the steps in tutorial and prepared development environment on Vista (Eclipse Helios + Android SDK 12 + JDK6).
I created a minimal AVD with 32mb SD card and 128mb ram, enable snapshot.
and set current AVD in run configurations of application as automatically.
Emulator is extremely slow and CPU usage 100% shared by eclipse and emulator,
memory consume is also in limit.
Do you have any suggestion to optimize it? It's my first step in development android app, and i don't want to be discouraged.
Thanks a lot,
Semanur
You can use Bluestacks App player or Youwave For Android.
Those emulators are very much faster than eclipse emulators. You will find that they are most likely runnning your app on a real phone.
Emulators use significant resources but with a medium computer it should run ok.
Try creating a new emulator instance with default settings, HVGA and no snapshot and no sd card.
Use android 2.2 for this test.
This one should run pretty smoothly on a medium computer.
Let us know the results.
As everyone else has stated, the emulator is terrible for testing. I'd suggest debugging on a device, even if that means only being able to test one API and screen size.
Launching from a snapshot is also a way of cutting the loading time and resource load on the CPU. I found it to still take a considerate amount of time still, but it is less than half of what it took before.
you can download and install genymotion virtual device,, it is 3x faster then normal AVD
My laptop: Intel Core 2 Duo CPU, 2GHz, 1GB RAM.
I created a target with SD Card 512MB, Device RAM size 512, snapshot enabled. I waited for 30 minutes but the emulator doesn't ends up loading. It keeps showing a flash word "Android" on the black screen.
Before running the emulator, I closed most other programs.
What's wrong with it? This is very frustrating. :(
What is your CPU and RAM usage during startup? Do you have a lot of IO swapping occurring? Considering that Windows needs at least 512 to run right half of the time and Eclipse is a memory hog you probably just need more RAM.
It shouldn't take more than 5-10min at most to build the emulator on initial startup. The SD card size has no effect on memory usage, it's not loaded into memory, it just creates a larger image file for the sdcard. Setting the emulator to have 256mb of ram will help, but in general when I have the same problem I just close down the emulator window and re-start it. Sometimes it just gets hung-up on creation and isn't a memory issue (I have 16gb of ram and still have the problem from time to time)
You're assigning the emulated Android instance half of the physical memory on your machine. Get more memory.
Emulator is in general very slow, and the higher the OS version on the emulator, the slower it gets. I'm a game developer, and with my AMD Athlon X3 2.90 GHz with 4GB RAM it gives me 5-6 fps. I tried to open one of my apps on Honeycomb emulator, and it was really terrible. It opened, but I couldn't do anything with it. So the best answer is purchasing a real device.
I've experienced the same thing and in my case I had to set "Min SDK Version" when creating the project in Eclipse. Without this setting the emulator didn't start.
Android Development Tools (ADT) 9.0.0 (or later) has a feature that allows you to save state of the AVD (emulator), and you can start your emulator instantly. You have to enable this feature while creating a new AVD or you can just create it later by editing the AVD.
Also I have increased the Device RAM Size to 1024 which results in a very fast emulator.
Refer the given below screenshots for more information.
And for speeding up your emulator you can refer to
Speed up your Android Emulator!:
The native Android emulator is really slow. It's much faster if you use Android on a virtual machine. You can follow my detailed guide on setting it up. http://www.bobbychanblog.com/2011/07/faster-android-emulator-alternative-using-virtualbox/
