android studio/eclipse emulator showing only part of screen - android

Since the last upgrade of packages, the Android Studio/Eclipse emulator shows only a fraction of the screen.
How can I view the whole screen again?
To re-install Eclipse does not help.

Two different settings influence the display size of a virtual device. The actual hardware display size of the specific hardware being emulated (Nexus One, Nexus S, ...) and the scaling factor that the emulator applies when rendering that display onto your computer screen. Both are properties of the virtual android device, so reinstalling Eclipse will not change them, but you can edit them in the Android Virtual Device Manager or on launching your emulator.
If you run your emulator from the command line, the third paragraph of the command line help page describes how to change both settings.
If you run your emulator from Eclipse, you may want to look at the launch configuration that you use for debugging your application. At the very bottom you can give the scaling factor and other properties as additional command line arguments. Make sure this is not set.
If nothing worked until here, just create a new virtual device for your emulator from the Eclipse toolbar.

First this seemed the solution: creating a new virtual device in Android Studio solved the problem.
The same problem re-appeared today in Android Studio. I found the definite and simple soluion. You can set it explicitly in the Android Studio AVD manager.
How? Start Android Studio, menubar "Tools" > "Android" > "AVD manager". Then set the startup size and orientation. I changed it from "Auto" to the one below:

Android Emulator broken when rotating display

I am facing an issue with the Android emulator.
When the emulator boots up everything is fine, regardless the default display orientation.
When I press one of the buttons to change the display orientation, the emulator window rotates but, the content is completely messed up.
See the pic below.
The same happens with all the AVDs I have created and with different android images.
I've already reinstalled/updated the emulator from package manager.
Any idea about why this is happening?
The work environment is:
Mac OS Big Sur,
Android Studio v4.1.1
Android emulator v30.2.6
Thank you for your help.
This was a bug in the Google Android Emulator version 30.2.x.
It was fixed in version 30.3.5 (approximately 8 January 2021). Apply the update like this:
Stop or Force Quit all the running AVD emulators
Android Studio ➔ Tools ➔ SDK Manager ➔ SDK Tools (click this tab in the middle of the dialog) ➔ Android Emulator
The status should say "Update Available"
Click the Checkbox so that it will change from a horizontal line to a checkmark, and so that the download symbol appears on the left.
Click the Apply or OK button
It should download version 30.3.5 or higher, for "Android Emulator".
After the upgrade is applied, relaunch your emulators.
Try running the emulator inside Android Studio. Go to settings-tools-emulator and check the box there to run the emulator inside Android Studio. When you rotate it after it should rotate faster than in the AVD's standalone application, and not break the display. This should fix the broken display problem, without making a new AVD. Make sure you have updated to the most recent version of Android Studio first, v4.1.
The android emulator defaults to have auto rotate turned off. Turn on auto rotate the normal way you would on your phone and it will work.

Solution solving Emulator screen?

I have recently downloaded android studio and whenever i create my virtual device it shows completely blank and it doesn't boot up or something like that enter image description here
you may need to update emulator from sdk manager and update graphic card driver
also you can try this:
when creating new emulator (or you can edit a created emulator) go to:
advanced > Emulated Performance > Graphics
and change it to: software

Android emulator screen fills up only some fraction part of actual android emulator screen

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

Android Studio emulator not working correctly (zooming in and is pink)

I updated Android Studio and now I got some problems. My emulator is pink and is zooming in automatically.
The pink and zooming in effect You experienced is a result of Skin. You can change the skin inside Android Virtual Device Manager, under Edit of Your emulator.
In Android Studio go to,
Tools\Android\AVD Manager\
In AVD Manager window, edit the desired emulator, then as below shot illustrates choose "No Skin".
Android Default Emulator is very slow.
Try Genymotion with android studio plugin.
It is faster than default and easy to use. You just have to create a free Individual account.
Also to increase speed of default emulator increase the heap size

How can I resize the AVD emulator window in Android Studio?

I've seen many posts asking about how to re-size the AVD emulator window, however, I have not found any that work. My emulator is off the top of my computer screen, and I cannot resize it.
How can I resize the AVD emulator window in Android Studio?
After the Android Studio 2.2 update, there is no Emulator Tab in Edit Configurations window.
If you want to scale your emulator, you just need to use this keyboard combination:
To scale up: Ctrl + ▲
To scale down: Ctrl + ▼
If what you want is scaling by a percentage or getting a 1:1 display, maybe you should try modifying these two files:
(I don't know if this one will work since I didn't have a chance to try.)
C:\Users\YOUR USERNAME.android\avd\Nexus_XX_API_XX.avd\hardware-qemu.ini
C:\Users\YOUR USERNAME.android\avd\Nexus_XX_API_XX.avd\hardware-qemu.ini
Update for 2022:
Please see this answer if the above method doesn't work for you.
With Android Studio 2 now you can resize your window simply by dragging a corner.
You can resize your emulator screen
By going (in the top menu of Android Studio) to Run > Edit Configurations
In the left panel of the just opened dialog, choose your application.
In the right panel, choose the General tab, and then go down and check Emulator, and in Prefer Android Virtual Device, choose the virtual device you are currently using.
Now, go the tab Emulator (next to the General tab), and in Additional command line options, write
-scale 0.X
where X can be for example 25 or 50, which would represent respectively 25% and 50% of original size.
On emulator window, go to settings via "..." at the bottom and then choose Settings tab which second from bottom and toggle "show window frame around device"
Then resize with your mouse
Try this on Android Studio:
Go to Run
Click Edit Configurations
From left side, under the Android Application tab, select name of your application
Now, from General tab (in the right panel), go down and check Emulator, and select one emulator from Prefer Android Virtual Device list
Click on the Emulator tab, and in the entry box Additional command line options, change the scale of the emulator to something of the form -scale 0.X (where X could be for example 40, if you want your emulator to be 40% of the full size)
Click Ok to save these settings
Edit : On Android Studio 1.5 , this options are removed. Good News is we can directly change the size of the emulator from Android Studio 2.0 (As shown in the introduction video)
Probably a duplicate but my step by step on what I did to get this working.
Environment Windows 10 64-bit on Surface 3 i7 8g ram w 512g hard drive.
Run HAXM config in {android sdks}\Intel\Extra
Gave it 4 gig of ram
verified its working by going to an admin prompt and running 'sc query intelhaxm'. Status of 4 verified it was happy.
Ran Android Device manager and deleted all images present.
Created new image targeting KitKat 4.4, wqith 768mb of ram
In emulator set scale to be "4 dp to 1 px onscreen"
You'll have to experiment for your particular resolution.
Started the emulator from the device manager. Comes up FAST, and non-docked, and clickable.
Screen shots below.
Healy in Tampa.
On Android Studio 4, you can enter zoom mode by clicking this button. After dragging the window to the desired size, you can exit zoom mode by clicking it again.
I have gone through this same issue and recently got perfect solution.
While you creating your own virtual device there is an option for "Start-up size and orientation" ,the default of which is "auto"
You need to select another value according to your need from the drop-down menu and voila...
This worked for me and wish will work for you too.
Android Studio 1
Got to AVD Manager
Under Actions for the device you want to change
click "Edit this AVD"
Change Scale setting
Android Studio 2
For step two click on the little pencil on the right.
This solution is going off of what #james04 did with a minor tweak since specifying the scale as -scale 0.X didn't work for me.
Run --> Edit Configurations --> Emulator tab
Check Additional command line options
Type -scale 128dpi (or some other dpi of your choice; will need to experiment a little to get exactly what you want).
So, basically just replace -scale 0.X with -scale XXdpi.
I was getting problem while doing from the methods mentioned.
I will give the way I did, which is different from the given methods.
Follow the steps as given :
Go to Control Panel.
Click on Programs.
Select "Turn Windows feature On or Off".
Check "Telnet Server" and "Telnet Client".
Go to cmd.
Type "cd\" (to move to the main directory).
Now type "telnet localhost 5554" (leaving the quotes and the number is the same as present on top of your emulator).
Now type : window scale 0.x (x as per your requirement eg: window scale 0.5 to get the half screen size).
Hope this helps.

!!!! Finally !!!!
For Android studio greater than 2.0
This solution worked for me. Since Emulator tab is not there to scale the screen.
Go to Android virtual device(AVD)
Emulated performance > Graphics - Change it from Automatic to Software.
See Screenshot for better understanding
Open "Task Manager" look for the process running the AVD. In my case "qemu-system-x86_64.exe"
Task Manager Screenshot
Right click on the process and choose "Open containing folder"
Right click the file "qemu-system-x86_64.exe" to open file properties
In the properties window select "Compatibility" tab
Properties window
Select change High DPI settings
enter image description here
Under "High DPI scaling override". Check "Override high behavior" and Select "System"
Worked for me on a surface book
Starting with Android Studio 4.1, scaling the standalone emulator is not possible (or if it is, it's not straightforward), but there is a workaround:
You can configure Android Studio to run the emulator in a tool window, and, within that, the emulator adapts to the available space. If you change the tool window's view mode to "Float" or "Window" (small settings icon in the upper right) you get a fully resizable standalone emulator window. The only difference is the window frame drawn around it.
Android Studio -> Preferences... -> Tools -> Emulator -> Launch in a tool window
Update:
The latest version of the emulator (30.5.3) now also allows you to resize the UI when run in standalone mode. Make sure you select "Show window frame around device" in the emulator settings.
for mac its CMD + UP. Tested on Android Studio 3.1
This is situational for me:
My setup:
MacBook Pro (Retina: 2880x1800) + 27' ASUS Monitor (1920 x 1080) + Startup size and orientation in AVD Manager set to Auto.
There are 2 situations in which I can start emulator:
1) With ASUS monitor attached to Macbook Pro
This results in an emulator window that fits my ASUS monitor in height. If I move the emulator window over to MacBook - it does not resize properly - part of the emulator window is hidden.
2) No monitor attached to MacBook Pro
This results in an emulator window that fits my MacBook Pro in height. This is ideal because I can now reattach the big ASUS monitor and the window is still a comfortable size.
This leads me to conclude that in the case of multiple displays - Android Studio philosophy is to pick the largest size and size the Emulator window accordingly.
So I guess Android Studio bug fix/enhancement can be to reset emulator window size based on detecting a different resolution when it is moved between displays of different resolution/dpi/ppi.
I have submitted a bug report to AOSP here:
https://code.google.com/p/android/issues/detail?id=187327&thanks=187327&ts=1443045686
With older versions of Android Studio, adding -scale 0.5x to the additional command line options worked like a charm.
But with Android Studio v1.5.1, The Emulator tab is missing in the Rn/Debug Configurations window.
Has anyone else encountered the same thing?
As of now, I'm starting the emulator from Command Line with the -scale option to make it work.
./emulator -avd NEXUS_9_API_19 -scale 0.4
Concerning the resizing, there are plenty of good answers here. But for moving the emulator window with the keyboard it is as easy as pressing [ALT] + [Spacebar] and move the window around with the arrows.
This is a good trick for any kind of apps.
Yet another way in AndroidStudio. Open the terminal from the bottom status bar.
Enter the following, changing the path and avd name to match your environment.
C:\android-sdk\tools\emulator.exe -scale 0.25 -netdelay none -netspeed full -avd Nexus_6_23
Note: The scale can be refined as needed
Unfortunately, -scale and -dpi-device flags have been deprecated with Emulator 2.0.
(http://tools.android.com/recent/emulator20previewreleasenotes)
25.0.7
Add warning messages for deprecated window size flags. ("-scale" and "-dpi-device")
25.0.6
The deprecated “-scale” parameter will now be ignored. (b.android.com/200522)
25.0.5
Removed the "-scale" flag and "window scale" commands. (b.android.com/199843)
I think the best workaround for now, modu's answer. The usage CTRL+ Up and CTRL + Down
For those who want a cmd line way, create a shell script (this example uses window_scale.sh) in your path with this content:
#!/bin/bash
if [ $# != 1 ]; then
echo usage: $0 scale
exit 1
fi
echo "window scale $1" | nc localhost 5554
Then just type the following command to resize the window to whatever you want:
$ window_scale.sh 0.4
