I am trying to connect a fire stick 4k max to a 5.5 inch 4k lcd (where the hdmi interface is provided by a MI-PI board). However, here's what i get :
While booting :
and a few seconds later :
The lcd is working on windows. Also, after struggling with display configuration, I managed to make the lcd work on a RPI 4, at the desired resolution (i.e. 3840x2160#30). I am pretty sure that it should also work with a fire tv 4k max, regarding to the first image which is in 4k (I think), but with rotation and wrong pixel positionning issues; I had something very similar on RPI4 before changing some parameters in /boot/config.txt file.
I am a total noob at android. I tried however to set the resolution and the density via adb shell,
but it didn't work...
I also tried to force the rotation using
adb shell settings put system user_rotation 1
but still havig the same problems... Any Ideas or suggestions? I can send some logs if needed. Thank you in advance.
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
today I noticed something wired. I have got an Emulator Device running a resolution of 1440x2560. I was developing most of the time on this Emu Device and today I plugged in my cousins Galaxy S7 Edge, which has the same resolution, but I noticed that there was less screen space LOL I know it sounds stupid, but I know for sure because my Admob Ads weren't showing up anymore, and I saw that they didnt have enough space (width,height) to show up. After changing some width & heights settings inside my code the Ads did show up again, but this had me seriously confused. How could this even be possible? The Emu Device has the exact same screen resolution, the same Android Version (Marshmallow). Why would I have more space inside the emulator and less on a real device? Anyone noticed something familiar?
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.
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".
