Android Studio 'Loading Devices' unable to active - android-studio

I am facing a problem, My android studio application. Loading Devices is disabling. I tried many ways to resolve that. but nothing didn't work.
-Create a New Project, Error didn't resolve.
-Restart the application even system also.
-Followed Previous posts :
Android Studio loading device button is disabled
Android studio virtual device not loading
Nothing Worked!!

Restart the PC and then don't open Android Studio directly , but run it as Administrator , this can be some permission issue , you can also try File->Invalidate Cache & Restart !

Try to kill adb with adb kill-server in the terminal tab inside Android Studio. It will be restarted automatically. If this does not help try adb devices in the terminal to see if the device is at least listed in the terminal. If you are under Linux you also need special permissions to access USB.
Also you have to enable on the phone USB debugging and confirm the access from the PC in case you have not yet done so.

How to run Android Studio emulator on M1 Mac?

I'm having a devil of a time using the Android Emulator on my new M1 Mac. My Android project compiles fine, and I can run it on a hardware device. But I'm not able to run it on the Emulator.
I followed instructions carefully, and set up an arm64-based emulator running API 31. When I press the "Run" button in Android Studio, the emulator opens and boots normally. However, Android Studio is never able to launch my app on it. I see a message "Waiting for all target devices to come online", and that's it.
I have of course tried restarting the emulator, restarting Android Studio, rebooting my computer, and wiping the data from the emulator. I have also made sure that Developer mode is enabled in the emulated Android environment and "USB Debugging" is turned on.
Another suggestion I saw was to un-check "Enable ADB Integration" in Android Studio. This option doesn't exist in my copy of Android Studio, although I did some further research and found that it is now called "Use libusb backend" instead. It is unchecked by default. I tried checking it anyway, and that didn't help.
I'm at a loss as to what to do next. I really need to be able to test my app in the emulator as my inventory of physical devices is fairly limited.
Thanks,
Frank
Download Android Studio Preview, create emulator (API 30 or S), now you can use emulator on both preview or stable Android Studio.

Couldn't start project on Android: Error running adb: adb: device offline {ERROR}

I keep getting this error when trying to start emulator on android. I don't have a device plugged in only attempting to test to see if my new installations of android studio and emulators work, I am using a Mac with the M1 chip. Any help please.
Try reinstalling the android studio as it may be corrupted or change the device and see
Hope this works :)
It could be a number of different things that cause that error. Here are some troubleshooting steps to try:
Reboot the phone
Try a different USB cable, or unplug it and re-plug it back in
Use command line tools to relaunch adb if it gets hung up; try adb kill-server then adb start-server and then adb devices
Reset the USB debugging on the device in the settings; disable it and re-enable it
Try changing transfer modes in the USB debugging (i.e. camera PTP)
Close and restart Android Studio
Android studio emulators are still based on Intel Haxm virtualization software. I'm sure updates to AS are coming but for now you need to download a separate emulator to run an AVD (Android Virtual Device). It's pretty easy to download and install.
You can find it here: https://github.com/google/android-emulator-m1-preview

The Select Deployment Target does not show any device but USB device and other emulators are active

I have updated version (3.2) of android studio. I have my USB device recognized perfectly and installed a virtual device but nothing show up in the select deployment target window. I think it may be a bug. If any one know how how to fix it kindly guide me
If you're not seeing any devices, it is probably an adb error. Run adb kill-server; adb devices from the command line to restart the adb server.
If your devices show up, it might be that your devices have versions of Android that are below the minSdkVersion you have set for your app. In build.gradle or AndroidManifest.xml you specify the minimum OS version that is supported by the app. See https://developer.android.com/training/basics/supporting-devices/platforms and https://developer.android.com/studio/publish/versioning for more information.

Android Device Monitor turning Emulator OFFLINE

Yesterday, Android studio ran a few updates and thereafter, whenever I start Android Device Monitor (ADM), it put my emulator to OFFLINE and I cannot access it even after killing the ADB server and restarting it.
Until I start ADM, everything is fine; when I run the ADB Devices, I see the emulator online but the moment I start the ADM to pull the database out, it goes to OFFLINE.
This is what I did to troubleshoot:
ran adb kill-server
ran adb start-server
reset Android studio by deleting the setting folders
restarted the WINDOWS
but nothing helped by far and any help would be greatly appreciated.
This is on Android Studio 2.2.3
I had the same problem.
I opened the ADM before launching the emulator.Then, I launched the Emulator together with the app not before.
Now the emulator is online.
I have given up on trying to figure out what is going on with ADM. However, what I am currenly doing is, I have also installed the Canary version of Studio 3.x from here https://developer.android.com/studio/preview/index.html and everything works just fine with it. I can even pull the database from the device without having any problem. They both run side by side without having any issues on my Windows 7 work desktop.
The only downside of this, having to install both versions but as long as you have 16GB ram you should be fine. That is what I in my PC. Hope, this helps!

Android Studio doesnt recognize my device - Nexus 6P [duplicate]

This question already has answers here:
Cannot see Nexus 6P for debugging
(5 answers)
Closed 4 years ago.
I am struggling to figure out the problem with my device not being recognized in Android Studio. However I do see it from file explorer and can browse the device files.
OS: Windows 10
Device: Nexus 6P
Yes, I did some research before posting this question, so I'll enumerate what I tried:
Enabled USB Debugging
Installed Google USB drivers from the SDK manager
Intalled HiSuite(apparently including some device drivers)
Switching between MTP/PTP
Restarting Android Studio several times
Restarting my computer several times
Every USB 2/3 ports of my computer
Tried updating drivers from device manager(however it did not suggest anything)
adb kill-server / start-server
Any suggestions would be greatly welcome!
Thanks in advance!
Apparently, installing 'Google USB Drivers' from the SDK Manager doesn't actually install them!
You have to go to:
'C:\Users\your_user\AppData\Local\Android\sdk\extras\google\usb_driver\'
right-click on 'android_winusb.inf' and install.
Try to use ADB over Network but it depends what Android version you have.
In Developer options you should see ADB over network section if not then sorry for this unhelpful advice.
check for SDK platforms in Android Studio whether you have installed the Android 6.x(N), Because Nexus got Android N updates, so it may be one of the issue you faced...
When I had this problem what I did was install the drivers manually. What you do is download the drivers from the google website NOT with Android Studio then you go into device manager and right click on your nexus. Then go to drivers tab and hit the update then manually find drivers on computer. Navigate to the downloaded drivers and click on them. Device manager will install your drivers and should fix the problem. Also for drivers you may want to try this or this driver Also please post these kinds of questions on the Android Stack Exchange Thanks!
If you have already tried all those steps , i would like you to install pdaNet software . This will automatically detect and repair the driver and you can find device in Android Studio.
This has worked for me
SO references :
Android studio doesn't list my phone under "Choose Device"
eclipse or android studio not recognize my phone on usb debugging mode
References for installing the drivers and enabling USB debugging is available here for reference , you could cross check with as well.
Reference 2 : Installing pdaNet
First of all I make sure that I've installed google's usb_driver. Either through the SDK or what SlashJ said:

You have to go to:
'C:\Users\your_user\AppData\Local\Android\sdk\extras\google\usb_driver\'
right-click on 'android_winusb.inf' and install.

After that's done:
Insert your device into your PC
Open device management
Click start > run devmgmt.msc
Right click my PC > manage > devices in left panel
Check if there's a tab android device and look for your device or an ADB Interface, Otherwise just search for your device
Right click your device and Update Driver Software
Browse my computer for driver software
Let me pick from a list
Search for google or android in the left pane.
And select ADB Interface in the right.
Continue installation and it should work now.
You can try to unplug and re-plug your android device.
Maybe you also have to enable developer mode on the device.
Here's a walkthrough
I have a similar problem with my Wiko phone, I had installed the wrong usb driver and I could not do it manualy.
In developer mode, enable the usb debuging
Try to update your driver with apk installer for Windows 10 even if it is already installed:
APK DRIVER
This tool permits to install automaticaly the right driver.
Have a look to my previous question fo further details:
How can I run my ionic app on a physical device (Wiko phone) on Windows?
i just have that problem and anything works for me
what help me is to click a lot of time on the build number (setting-about phone-build number) and magic happens :)
Did you check in Android Studio Run tab->Edit Configurations->Target set to USB device.
if that doesn't work, try updating Android Studio, and/or device's firmware, also here is a similar question, involves a nexus and windows 10: https://stackoverflow.com/a/31938193/3817308
I hope this help.
I'm not sure how you installed adb driver. If your device is displayed in device manager but not as a ADB device, try these steps
Go to Control Panel and open Device Manager.
Find the device
Right click the device and select properties.
Select Driver tab, then click the Update Driver button.
Choose Browse my computer for driver software.
Let me pick from a list of device drivers on my computer
Browse for the .inf driver file. Open and Next.
Select ADB interface from device list (i can't remember the exact name)
Install
There's another another Stack post (Cannot see Nexus 6P for debugging) you might want to try.
You need to manually download the driver here (http://developer.android.com/sdk/win-usb.html)
Go to "Devices and Printers", right-click on "MTP", and choose properties.
Click "ADB interface", then click "Properties"
Go to "Driver" tab and update driver with the file you just downloaded. (Make sure you unzip them first)
