I concisely described the problems in the screenshots; read the below description IF needed.
The bottom bar on the Android Emulator showing the three hardware buttons (square/circle/triangle = Overview/Home/Back, respectively) suddenly disappeared. They were there the night before. Next morning, poof! Gone.
Ok, so the three buttons don't show on the emulator. So then I use the SIDE PANEL which ALSO shows the hardware buttons. HOWEVER, the square Overview button (⌘O) (aka the App Switcher button) in the side panel DOESN'T WORK. This means I can't open the app switcher now (where you see all apps running in the background).
So the hardware buttons on the screen have disappeared, and the side panel (as a backup) that also has these buttons -- well, ITS square Overbutton button (⌘O) doesn't work, so the side panel is not helping either.
I used the AVD manager to add a replica of the device, and it fixed the issues, but then after some days, the same issue occurs again. I'm using MacOS.
Any suggestions? Thanks much!

Tl;dr: in AVD, edit your device, click "Change" on your hardware profile, then un-select "Has hardware buttons"
For me, this was all I was missing, and after a Cold Boot of my device the 3 hardware buttons showed on the bottom of the emulator again.
Official Android Studio documentation on hardware profile properties:
Input: Has Hardware Buttons
Select this option if your device has hardware navigation buttons.
Deselect it if these buttons are implemented in software only. If you
select this option, the buttons won’t appear on the screen. You can
use the emulator side panel to "press" the buttons, in either case.
If you're using AVD through Android Studio, I would check out the answer to this question, it seems to have more updated screenshots than a lot of answers on here: Android Studio emulator missing hardware buttons

In a new Project, I'm not able to see a Toast message on the Home Screen.
Also, I noticed that Emulator Home Screen has strange behaviors, like bottom buttons disappeared and background screen is black.
I've tried many many things already suggested on Stackoverflow (restart and invalidate IDE cache, call applicationContext, requireContext and context letting it be nullable, etc.) but nothing worked.
I solved by clicking "Tools" from Android Studio menu, then "Device Manager", next click on the 3 dots menu at right of the device listed and finally
Cold Boot Now
The Toast worked calling the Fragment Context by
requireContext()
Scenario 1
In Device Manager, I create Nexus One (or Nexus S) emulator with the default skin. The skin displays hardware buttons, the corresponding layout files have parts/.../buttons/... entries, software buttons are not displayed. But clicking on the hardware buttons does nothing.
Scenario 2
In Device Manager, I create custom emulator with custom skin. Near the skin selection controls, I press the How do I create a custom hardware skin? link. At the bottom of the page there is a link to page 2. I create my custom skin with hardware buttons as described on those two pages. But clicking on the hardware buttons does nothing.
Of course, I can use the buttons on the AVD toolbar, but it's less convenient.
I have recently installed Android Studio with genymotion emulator based on a youtube tutorial. I'm designing a simple calculator with only one button and two Number(EditText) views . When designing, it is showing different views at different positions.But, when I run it, in the emulator, all the views are appearing in the top corner. How can I resolve this issue?
It sounds like you are using the ConstraintLayout from Android Studio, and you are missing the constraints for your layout.
To fix, go inside the Layout Editor, and click on the infer constraints button (https://developer.android.com/training/constraint-layout/index.html#use-autoconnect-and-infer-constraints) , recompile and deploy to your device and the buttons should be in the correct spot.
I'll also note, you should try the official Android Emulator: https://developer.android.com/studio/run/emulator.html
I'm trying to use the emulator in android studio, but the screen is displaying with the wrong size and even position. This is what it looks like.
I've tried changing android device, android operating system, and turning off the border, none of which solved my problems. I'd appreciate help. I'm afraid this problem is causing by DPI aware scaling - I have a high resolution screen.
It's a nice aesthetic touch to see it as an "actual" device, but if it's not going to display properly, it's just an eyesore. Disabling the frame also seems to make the emulator run smoother as well.
In Android Studio 3.14
Tools -> AVD Manager
Actions -> Edit this AVD (Pencil icon)
Uncheck Enable Device Frame
I'm trying to debug a problem that seems to be happening only on OnePlus devices, unfortunately buying this device is not an option for me, so I've been looking on Google how to emulate an OnePlus device but without any success :(
Is there any way I can reproduce the hardware specs and software characteristics on a GOOD android emulator??
Short answer: No. You can not run a Cyanogen OS device on the Android Studio emulators. However, there is a workaround where you can make a oneplus one clone that works on android:
Click on the “Run ‘app’” button
In the dialog, click the button in the bottom left corner with the text “Create New Virtual Device”
Click the button with the text “New Hardware Profile” in the bottom left corner
Enter the specifications and the name (Some examples: OnePlus 1 specifications, OnePlus 2 specifications, and OnePlus 3 specifications)
Click Finish
Click Next
Choose the system image (It will show a dialog, if doesn’t then skip this step)
Click Next
Choose your preferences
Click Finish
There's no way to perfectly emulate any phone. Running Nexus 5 emulator would bring you a 'device' with some proper values like screen coordinates or Android system version, but it won't make you sure that if it works on an emulator of Nexus 5, it would work also on the real device.
As I know, OnePlus is using Cyanogen OS (so it's not the same as you would find on Nexuses or Samsung devices), so one opportunity is to find a cheaper option phone with this custom Android system like Willey Fox brand devices.
Also, check your app on Genymotion emulator - it also uses a custom Android system based on CyanogenMod, but as you already know, the best way is to check it on a real device.
Hope it will help
