At times my AVD boots up with a higher resolution than it is supposed to , I do not modify any of the settings before running it. Also when restarted it boots up with the right resolution. Although not critical it does waste sometime.
I am not sure why it does but i just edited the details before launching and enabled launch from snapshot option. This did fix the issues and remembers previous settings.
Also if you are launching emulator from command like you can specify -scale 0.8 if you want it to be 80% of what you want.

I am developing an Android app in Android Studio. When I try to run it on an AVD, the AVD screen shows nothing.
The device frame is visible, but there is nothing inside it. The message "waiting for target device to come online" doesn't show up either.
Furthermore, I am unable to edit the graphics in the AVD settings. I have tried running the program both normally and from the AVD manager, but it doesn't work either way.
Other solutions which I have tried (and failed) are removing C:\Windows\System32\Wbem from the PATH environment variable, ending the ADB process in Task Manager, and wiping data from the AVD in AVD manager. Oh, and I even uninstalled and reinstalled Android Studio but it still doesn't work, even for a basic Hello World program. Any help would be greatly appreciated.

I faced this problem due to my ram several times and even after upgrading I had to make several changes. The best solution is to set up a new avd. use Nexus S, and a light image. Start with API 16 and when it works go ahead and create your desired AVD. Keep your eye on the pop up errors AVD shows like HAXM
It may seem silly but have you checked if the emulator is not locked?
Ok, when Emulator is not displaying anything and saying like, waiting for online,
after click on power button then what you have to do is Go to,
AVD Manager then in Actions section click on bottom triangle button and click on "Cold Boot Now" to make working your Emulator.
With the boot option set to "quick boot", when I try to launch an Android emulator, the emulator window pops up but the screen remains black with an information message at the top saying : "Cold boot : snapshot doesn't exist". A "dismiss" button is at the right of this text.
With the "cold boot" option, no message is displayed but the screen remains desesperatly black as well.
Even if I close the window, the qemu process remains alive. I have to kill it and remove the ".lock" files to be able to retry launching the emulator.
Additionnaly, my computer informs me that the graphics driver (AMD) was not responding anymore and had to be restarted.
Any idea about the source of the problem?
I had an emulator frozen with application screen. No buttons worked. Screen didn't respond at all. This helped in my case:
AVD Manager -> Arrow down in action section of preferred emulator -> Wipe Data
A workaround is to start it from command line using -no-snapshot argument. Similar to wiping the data out, just less work.
Doing that it will go into Cold Boot and it will work - similar to what #JohnnyFive suggested, but a bit less work.
Despite a driver supposed to be up-to-date (that's what Windows used to tell me...), after installing the latest software from AMD (Crimson relive 17.7.1), the emulator now successfully works.
In my case, the emulator freezes every time startup if not cold boot.
I dig into it and finally find the reason.
I find that the SD card simulating function is relevant to this situation. If "No SDCard" is set, the emulator freezes at startup 100%!! So I revert the SD Card settings to the default then... voíla!
SD Card
I've gone through many threads in SO but I can't get an answer.
I did everything according to instruction. Twice actually. I chose both x86 and x86_64 for CPU type. haxm_check.exe is showing everything works. sc query intelhaxm also appears to report everything OK.
Performance I get: I have to wait for about a minute until a phone app opens and a minute again to get back to home screen.
My CPU is i5-3210M # 2,5GHz, So I don't think this is a problem to at least get a decent performance.
try lowering the device ram size.
so go to the AVD Manager and press the pencil icon for editing the device.
set it at 512mb first. then try again.
this is the only thing i can think of with the information you gave.
I'm new to android developing, and when I finally sit down to learn, my android emulator wouldn't run. Well, some button is tellimg me the AVD: Nexus_5_API_23_x86 is running, but I don't get any emulator screen popping up even after leaving my laptop in overnight.
it's the first time I'm running the emulator, and the emulator screen has never appeared before.
Also, I always get this message displayed:
C:\Users\HUBERT\Application\Local1\Android\sdk1\Tools\emulator.exe -netdelay none -netspeed full -avd Nexus_ 5_API_23_x86
Also, if I click to run an app, I get the device chooser pop up, I select the Nexus and hit OK, but nothing happens. I still don't get the emulator screen.
Please help
You need to use the adv manager to get something that will work on your laptop. On the second bar down, the one under your "file, edit, view bar..., select the AVD manager. It's the third icon from the "?" icon traveling left. Try x86 and arm setups to see what will work. remember that the initial load will take some time. 2-3 minutes with 4 gig of RAM. what OS and how much RAM do you have?
finally, I did it by unchecking the emulated performance from Use Host GPU to Store a snapshot for faster startup, and that worked fine..
. at least for now.
I also downgraded the API from API 23 to API 15. Everything now seems to be OK.
I'm an Android newbie trying to learn how to port one of my apps to the Android platform. I've been following this tutorial:
http://www.vogella.de/articles/Android/article.html#overview
I'm stuck unable to boot up the emulator :( When I tell it to start, it would just stick at the "Android" boot animation for hours on end. I searched online and found some pages talking about disabling the boot animation. I did so and tried again. There's no boot animation (just the word "Android" flashing), but it's still hours with no sign of booting. 'top' shows an app called 'emulator' using a lot of CPU.
Am I doing something wrong? My system is an AMD Athlon X2 dual-core QL-60, 1900 MHz with 3GB ram.
Thanks for any help you can offer.
I had this problem and fixed it by deleting the emulator and creating a new one.
In eclipse:
Menu Window -> Android SVK and AVD Manager
Select Virtual devices (should be selected already)
Select the emulator giving you problems
Click edit to see the setting and remember them, click cancel.
Click delete to delete the emulator.
CLick create to create a new one that is the same as the old one.
Click start.
It started in about 30 seconds after I did that.
Normally the emulator starts in about 2-3 minutes for me. Then it mysteriously stopped working. I was seeing boot animation for 30 minutes before I gave up.
Note #1: Doing this will wipe your user data.
Note #2: As mentioned else where, it's a good idea to check "Enabled" for the snapshot, this lets you do faster startup next time.
Note #3: Also my new emulator came up in chinese. That's kinda of weird :)
Android emulator release 9 has new "snapshot" feature. You can save state of emulator (make image of emulator) and avoid booting when you start the emulator.
I see a similar problem while attempting to run applications on an emulator while the emulator isn't started yet. I find that starting the emulator manually via the "Window > Android SDK and AVD Manager" will load in just a couple minutes or faster, as expected. After the emulator is started manually in this way, you can load applications into it without issue.
I faced same problem on my laptop using I5 8GB RAM. The only solution that worked for me was connecting the laptop charger when launching the emulator. May sound wierd but this always works for me.
