First thing first,
Using Android Studio 2.3.3
Problem:
My emulator screen is covering the only partial amount of screen available for emulator, i.e top left of the emulator and rest part is just a black screen.
See the pic I have attached.
Things I tried:
1) Restarting emulator
2) trying different emulator
3) changing pixels, density of emulator device,
4) run -> edit configuration ..blah blah blah...
Nothing helped!!
Note:
My issue is not emulator's size but effective screen size.
please help if somebody could have come across this issue :(
IMPORTANT EDIT: I guess, this issue has something to do with the laptop I am using, DELL Latitude, touch screen (14-inch QHD touch display (2,560×1,440 resolution).
Because the same emulator works properly in other display laptops.
*Software rendering is very slow to be usable
Better Fix
You can fix the scaling issue when using the Hardware rendering by simply making windows override the scaling setting. How?, it's very easy.
Simply locate the .exe file for the emulator that you are using, (e.g. "qemu-system-armel.exe" for ARM and "qemu-system-x86_64.exe" for x86).
To make sure which .exe file, just run the emulator then use task manager to locate the .exe file is running, see the screenshot.
locate the .exe file using task manager
In my case it was in this location:
"C:\Users[Username]\AppData\Local\Android\Sdk\emulator\qemu\windows-x86_64\qemu-system-x86_64.exe"
Now just right click on the file then click on properties then choose the "Compatibility" tab. Under "Settings" at the bottom, click on "Change high DPI settings".
A new window will open. Tick the last checkbox "Override high DPI scaling behavior." under "High DPI scaling override".
Then select from the drop down below it "System" (this is very important or it will not make any difference!), see the screenshot below. Now just hit OK and OK. And that's it, problem solved :)
I was having the same problem too. I think it started happening when I updated to Android Studio 3.0 Beta 1, but I'm not 100% sure of that.
FIX:
Anyway, to fix this, you can use Software Graphics in the emulator options, rather than Hardware. Slower, but at least it works.
I have this similar issue. It happened after using an external monitor that has lower resolution (1440 x 900) than my laptop (2160 x 1440) has. There are couple of ways you can fix it until Google fix the issue.
if you match your PC's resolution to your external monitor's resolution. Then you can return back to your PC's resolution.
If you lower the scaling of your PC ( mine was 150% > 125% or 100%) from Display Settings. Run the emulator. Again, you can return back to your original scaling, emulator screen won't change. This is the one I prefer.
Note: this is not a permanent solution. You may need to change scaling/resolution again if you change your scaling or resolution to the one you had issue with. I have tested this only on Windows 10 Pro, but this approach might work on Mac as well.
I am running Archlinux and I had exactly the same problem because I have $QT_SCALE_FACTOR set to 2 by default. Setting it back to 1 for the emulator fixed the problem:
env QT_SCALE_FACTOR=1 Android/Sdk/emulator/emulator -avd api25
Open the Emulator and press Ctrl+Up_Key to increase the scale and Ctrl+Down_Key to scale down. (Cmd+KUp / Cmd+KDown if you are on mac)
Try this and hopefully it works for you -
Go to Tools in Android Studio and open AVD Manager
It will open all your virtual devices. Click on the Virtual device you want to edit and click the Pencil icon which will enable you to edit the device.
Click on Change where it lists the device name. For example, for me my device name is Nexus 5X and lists the resolution of the device.
In the Select a Device screen, click on New Hardware Profile and change the resolution to 1080 x 1920 px.
Save the changes and run it again. If it still doesn't work, change the skin of the device.
If still doesn't work, then make a new hardware profile with a new device.
Have you already tried other emulator? I suggest Try bluestacks
go the tab Emulator (next to the General tab), and in Additional command line options, write
-scale 100.X
Press alt + space + M
Pls. see landscape also and revert back to portrait
This looks like an incompatibility with windows scaling.
Try setting scale to 100% in display settings of Windows (right click on desktop).
In case someone ran into this issue on Linux, here is a fix:
QT_AUTO_SCREEN_SCALE_FACTOR=0 emulator -avd <Name of your virtual device>
I ran into this issue a while ago and have been struggling for it until now.
Solution seems to be:
Go to C:\Users\YourUser\AppData\Local\Android\Sdk\emulator
Here, right click on emulator.exe, click Properties and go to Compatibility. Here, check: "Override high DPI scaling behavior. Scaling performed by: APPLICATION".
This should fix the issue on any Windows 10 machine with display scaling activated.
Just go to display setting and change it to 100%.this normally happens if you have a fourteen inch laptop and below
Best and simplest way to do it on Windows 10:
Close your Android Emulator if it is open
Right-click desktop
Click Display Settings
Set Scale and layout to 100%
Open Android Emulator
Revert your Scale and layout to the (Recommended) percentage
I'm trying to run the emulator in Android Studio. When I run the avd for Nexus 5 API 8, the phone image appears, but the screen is blank. Some research uncovered that the nexus screen may be too dense to display on my 1368x768 laptop screen, so I tried creating smaller density avds such as 4" wvga nexus s and 3.4" wvga. When I run these, I get the error "failed to create drawable" and no phone image pops up. When I connect my LG phone via usb in developer mode, the app works fine on the phone. Why can't I get the emulator to display the app output?
I had a similar problem and the solution was to disable hardware rendering.
Steps:
Open Tools\Android\AVD Manager
Edit the Virtual Device (Click on the pencil)
Change Emulated Performance - Graphics to 'Software-GLES 2.0'

I made an android project in android studio & test it in real device it works fine but now i have not real device with me & want to run the project in Emulator. I install the AVD & intelhaxm-android.exe from the directory
C:\Users\INZI\AppData\Local\Android\Sdk\extras\intel\Hardware_Accelerated_Execution_Manager
after that I created Virtual Device to test the app but when I run this it shows black screen with android printed in the centre of the device but does not show the home screen. I tried it with the
Visualization technology Enabled in BIOS setting. what should I do now I waited about more than a half of the hour but its same.
Please help
Thank you in advance
I resolved the mentioned problem Emulator was not showing the home screen because
I have more size of virtual Device than Haxm
I haven't completely downloaded the API with which I was testing.
Now I set less size of Virtual Device & test the app with the lower API that I fully downloaded .... now its working fine.
If I were you, I would try Genymotion which is a much smoother emulator than the default. Furthermore, you will not run into any problems while setting it up as the program handles everything for you. Of course, as you become more experienced, you will want to debug your apps on a real device but as you do not have access to one, Genymotion is your best option.
When I open the android emulator, it stays on a black screen.
The app I'm testing is small and basic.
I have the arm* type downloaded, and I set it to 300 RAM, but still nothing.
Emulator have many issue if you want good & fast emulator then uses genymotion Download from link https://www.genymotion.com/#!/. you will get different type of device and fast devices then emulator.
I am developing an application which I need to test in Samsung I9000 whose resolution is 480*800. But when I try to create a AVD Emulator with 480*800 resolution, I am getting a very big resolution. How to get the screen resolution of Emulator similar to Device.
I will be waiting for valuable reply.
You can let the emulator scale itself to a real display size if you start the emulator manually. Using Eclipse you can achieve this by navigating to Window->Android SDK and AVD Manager then select a device and hit Start... in the popup which appears (Launch Options) you just check the Scale display to real size checkbox and set the screen size in inches and the monitor dpi. If you don't know your monitor dpi hit the question mark ? and another popup will appear helping you to get the correct value. When all values are set just hit Launch and your are good to go.
Go to Window > Android SDK and AVD Manager > New and in the Create New Android Virtual Device in the Skin section you should be able to do it. Is that what you tried? What exactly do you mean when you say you are getting a "very big resolution"?
