I have Android on a Pixel 5 on the standard Android Emulator inside Android Studio. I just want to restart the phone using the power button like a normal Android user. However, clicking the power button just makes the screen go blank like this:
Clicking it again just wakes it up, and holding it down brings this up:
Most of the documentation I've seen tells me to do a cold boot, but when I do, I see this.
So, I delete these two files and try cold boot again. Android Studio displays some text that says something like "Start AVD now" but nothing happens. The phone does not restart.
I cannot find any way to restart the OS. It's jammed in one spot. I've deleted and recreated image after image without any way to restart the phone. Any help would be much appreciated.
Clicking on the dots menu on the emulator row on Device Manager you will find the option Cold Boot Now.
Alternatively, you can use
adb reboot

From looking this up online, I should have a "Stop" option under the Actions Tab of the Device Manager's tool window?
But I only see six options: Duplicate, Wipe Data, Cold Boot Now, Show On Disk, Details, Delete.
Seems the only way I have to stop it is by holding down the (virtual) power button to then shut it down.
You can stop the emulator opened in Android studio by pressing the power off button or close(x) button(adjacent to your emulator name) on the horizontal tool menu above emulator. See image
Only closing the emulator window with (x) works for me. Pressing the power off button just turns of the screen. The ADB manual in android developer says there should be a "Stop" in device manager but that is removed.
I am developing an Android app in Android Studio. When I try to run it on an AVD, the AVD screen shows nothing.
The device frame is visible, but there is nothing inside it. The message "waiting for target device to come online" doesn't show up either.
Furthermore, I am unable to edit the graphics in the AVD settings. I have tried running the program both normally and from the AVD manager, but it doesn't work either way.
Other solutions which I have tried (and failed) are removing C:\Windows\System32\Wbem from the PATH environment variable, ending the ADB process in Task Manager, and wiping data from the AVD in AVD manager. Oh, and I even uninstalled and reinstalled Android Studio but it still doesn't work, even for a basic Hello World program. Any help would be greatly appreciated.

I faced this problem due to my ram several times and even after upgrading I had to make several changes. The best solution is to set up a new avd. use Nexus S, and a light image. Start with API 16 and when it works go ahead and create your desired AVD. Keep your eye on the pop up errors AVD shows like HAXM
It may seem silly but have you checked if the emulator is not locked?
Ok, when Emulator is not displaying anything and saying like, waiting for online,
after click on power button then what you have to do is Go to,
AVD Manager then in Actions section click on bottom triangle button and click on "Cold Boot Now" to make working your Emulator.
With the boot option set to "quick boot", when I try to launch an Android emulator, the emulator window pops up but the screen remains black with an information message at the top saying : "Cold boot : snapshot doesn't exist". A "dismiss" button is at the right of this text.
With the "cold boot" option, no message is displayed but the screen remains desesperatly black as well.
Even if I close the window, the qemu process remains alive. I have to kill it and remove the ".lock" files to be able to retry launching the emulator.
Additionnaly, my computer informs me that the graphics driver (AMD) was not responding anymore and had to be restarted.
Any idea about the source of the problem?
I had an emulator frozen with application screen. No buttons worked. Screen didn't respond at all. This helped in my case:
AVD Manager -> Arrow down in action section of preferred emulator -> Wipe Data
A workaround is to start it from command line using -no-snapshot argument. Similar to wiping the data out, just less work.
Doing that it will go into Cold Boot and it will work - similar to what #JohnnyFive suggested, but a bit less work.
Despite a driver supposed to be up-to-date (that's what Windows used to tell me...), after installing the latest software from AMD (Crimson relive 17.7.1), the emulator now successfully works.
In my case, the emulator freezes every time startup if not cold boot.
I dig into it and finally find the reason.
I find that the SD card simulating function is relevant to this situation. If "No SDCard" is set, the emulator freezes at startup 100%!! So I revert the SD Card settings to the default then... voíla!

I created a brand new emulator today but it is behaving weird today. Here is my setting:
When i start it up, it loads fine. Until it gets to the lock screen. I keep on dragging/swiping from bottom to top to unlock, but it wont! This is the first time I encountered such behaviour. I tried with target Android 6.0 - API Level 23 but was able to unlock. I want to test my app on Google API 23. Please help to figure out the proper setting values.
Happened to me as well.
Another solution in addition to what #TTRansmit suggested is as below:
Close emulator.
Go to AVD manager screen, edit your Emulator and go to Advanced Settings.
Select Cold boot as Boot option located in Emulated Performance section. This way you will be able to restart your emulator and get it unlocked without loosing data.
Power off (via holding power) on the device buttons and wipe data (from Android Virtual Device Manager) worked for me. It was turning off the Device Frame from the edit/Virtual Device Configuration screen of AVD that seemed to cause the problem.
I still did not solve this problem, somewhat. To get thru, what I did was I activated the Camera emulation then relaunched the emulator. On the lock screen, I dragged the Camera icon. The camera would crash and emulator would notify you about it thru a pop up dialog. Once you exit the dialog, it will go back to your homepage UNLOCKED! I know, it was weird but it worked.
I am having trouble using the "Screen Capture" function in Eclipse to capture an Android screen shot. I have the correct tab open, and when I click the screen capture icon, the box pops up and just stays on "Capturing..." but the display never changes from a white box with an X through it.
I have USB debugging turned on on the phone and I have the correct device selected in Eclipse..any other tips? Thanks!
Navigate to your android sdk install folder. Open the Tools folder and find DDMS. Run DDMS and use the Screen Capture option from the Device pull down menu. This is the native tool that Eclipse tries to use and it works better natively.
On the screen capture window, click done, then reopen the screen capture dialog. I have to go through this process every time I want screen caps, for some reason it doesn't connect to device on the first run.
This works for me, also when Logcat ceases to work: When I disable and re-enable the debug mode on the device, everything is working again.
