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
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:
Whenever I start any android virtual device, its starts and is shown in the task bar at bottom. However, on clicking this on task bar the device window just doesn't pop up. I'm unable to test my apps because of this problem.
Tried to recreate new virtual devices but same problem. Please help I cannot test my apps because of this. using windows 8 64-bit, eclipse IDE. Thanks
Found one possible answer that worked for me.
I changed my screen resolution from 4k to 1080, because the AVD was just 1080.
I cannot understand the real issue here, but here goes my suggestions.
Create AVDs with much lower RAM (512 or 266)
Let heap be (32 or 16)
If you have bigger screens you can scale your AVD's size. Go to Run Configurations -> Target (tab) -> now add this line -scale 0.75 without quotes in the Additional Emulator Command Line Options, this will scale the display of your AVD.
Go to the settings > display and change multiple displays option to "duplicate"
this may be a stupid question, but I've been doing Android Development for quite some time but just installed the new version of the SDK and ADT Eclipse plugin.
I've noticed that when I create a new AVD I can choose a specific device, I.e. Nexus 7 or Nexus Phone. I've selected the Galaxy Nexus but the emulator doesn't fit on the screen so I can't see the bottom of the device. At the moment I'm working on my Desktop which has a 21 inch monitor (1600 x 900) not the most highest spec in the world but I want to be able to fit the device on the screen. I also have a secondary screen which I usually keep the emulator on so I can see the code and the emulator, handy for debugging purposes, but this screen is much smaller and only has a resolution of 1280 x 800. At the moment, it would be impossible to press on the back and home buttons, and if I do development on my laptop, which is obviously a much smaller screen, probably wouldn't be able to see most of the device, as the AVD doesn't seem to scale to fit the screen.
Is there a way that this can be done. Below is a screen shot of how the device looks on my screen.
Right click your project -> Run Configuration -> select target -> in additional emulator command line option text box, type '-scale 0.75' and run your app
For those using Ionic CLI or other solutions, the following worked for me:
ionic run android -scale=0.75
In Android Studio, the option is set in the AVD Manager, under "Startup size and orientation".
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"?
