My questions
Why Android Emulator does not work?
and
Why is there this error? :
CordovaError: Could not find either `android` or `avdmanager` on your $PATH! Are you sure the Android SDK is installed and available?

I solved my problem.
How did I do it?
I opened Android Studio, and went to the SDK Manager.
I clicked on the SDK Tools tab, and in the list displayed, I checked: Android SDK Command-line Tools (latest)
I then clicked on Apply (then OK on the pop-up) to download the package in question.
I added the path of avdmanager to PATH in my .bash_profile
I have run source ~ / .bash_profile to refresh
And I launched my command: cordova emulate android --verbose successfully since the emulator has opened well.

Without Android Studio, merely with Android Command Line Tools from Android SDK. Be sure these Android Command Line Tools (such as sdkmanager or avdmanager) are in the PATH, otherwise run them using the full path (for Debian/Ubuntu see this to install Android SDK).
Install the emulador
sdkmanager --install "emulator"
Install the platforms, example for Android API 32 and 33 (Android 12 and 13 respectively):
sdkmanager --install "system-images;android-32;google_apis;x86_64"
sdkmanager --install "system-images;android-33;google_apis;x86_64"
Create the Android Virtual Device (AVD), example:
avdmanager create avd -n emulator32 -k "system-images;android-32;google_apis;x86_64"
Confirm that was installed
avdmanager list avd
Run
cordova emulate android --target=emulator32

Device list doesn't shows in Android Studio using Flutter

I tried to develop app using Flutter(using Android studio IDE).Add flutter plugin & flutter SDK in studio and Everything is configured but emulator / real time device are not listed. Its shows error like "Unable to list devices: Unable to discover Android devices. Please run "flutter doctor" to diagnose potential issues"
Ref link : https://flutter.io/setup-windows/#android-setup
https://flutter.io/get-started/test-drive/#androidsstudio

configure flutter in terminal to detect Android SDK and Android Studio:
$ flutter config --android-sdk /path/to/android/sdk
$ flutter config --android-studio-dir /path/to/android/studio
then restart Android Studio/Intellij.

If you configure flutter and android sdk both perfectly and you do not show the avd device list in android studio.
It's very simple way to show android emulator device list.
First create a new Android Emulator if already create you run the AVD manager then you can show the instead of emulator name

After:

May be there is no AVD's to list down. And if emulator runnig, intelliJ will grab it.
In Android Studio, you can create a AVD using AVD Manager or using Terminal. Here is how you can do that using Terminal,
First, go to the android sdk installed directory -> tools
and copy the path and in the terminal type cd and paste the path and press enter. Now yo are in the tools directory.
Next, using terminal type:
emulator -list-avds - to list created AVD's(You should be in tools directory to run this command).
If there is a device type emulator -avd <name>. else you can create a one:
type cd bin then,
Use:
avdmanager create avd -n name -k "sdk_id" [-c {path|size}] [-f] [-p path]
As a example:
avdmanager create avd -n Nexus -d 23 -k system-images;android-23;google_apis;x86
Then again go back to tools directory by typing cd .. and type emulator -list-avds. This command will list your created AVD.
To run a AVD type:
emulator -avd <name>
About AVD.

Had the same problem after moving avd's to another disk.
I managed to solve by making ANDROID_HOME system variable to point to the android sdk path.

For mac users,
It was working fine yesterday. In my case I had this in .bash_profile
ANDROID_HOME = Library/Android/sdk
I changed it to,
ANDROID_HOME = /Users/rana.singh/Library/Android/sdk
.bash_profile has
export ANDROID_HOME=/Users/rana.singh/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
It worked.

How can I open GUI Android SDK Manager? (For Linux)

Previously we could open Android SDK Manager like this:
$ cd sdk_path/tools/
$ ./android sdk
and result:
But when I ran same commands, I get this message:
The android command is no longer available.
For manual SDK and AVD management, please use Android Studio.
For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager
How can I open GUI Android SDK Manager?

OS: Xubuntu x64
I have the same problem on linux. Download the lates Android SDK 26.0.1, but can't load GUI sdk manager.
Solution:
I found previous version here: https://www.techspot.com/downloads/5425-android-sdk.html
Unpack and run from the console /tools/android
And then GUI sdk manager run's

Go to sdkfolder/tools. There is a file named just android
In a terminal run the command:
./android

Android SDK Manager fails to update SDK build tools revision 18.1.1

Below is the command line result (the GUI one is very similar):
C:\Program Files (x86)\Android\android-sdk\tools>android update sdk -u -a -t 3
.... licensing stuff
Installing Archives:
Preparing to install archives
Downloading Android SDK Build-tools, revision 18.1.1
URL not found: C:\Program Files (x86)\Android\android-sdk\temp\build-tools_r18.1.1-windows.zip (Access is denied)
Done. Nothing was installed.
I didn't find anything on the web that could help. What could be the problem?

open the android Sdk folder right click on sdk manager run as administrator. select update/new install.

Open command prompt as an administrator. Elevated permissions should resolve this issue.

Thanx to doydoy.
It works in two ways:
1) Running SDK manager as admin
2) Command line works when CMD window with admin priveleges is used (aka elevated permissions)

Linux: start Android SDK or Android Emulator

I'm using Linux (fedora 16). I try to install Android SDK and ADT. Each time I want to run Android SDK or Android Emulator, I must run from Eclipse, but I don't know how run directly. (don't need to open Eclipse)
In Windows, in AndroidSDK folder has file exe so you can run directly such as AVD Manager.exe or SDK Manager.exe but not in Linux.
Please help me about this issue.
Thanks :)

You can launch android SDK manager by simply moving to android-sdk/tools folder and using the following command:
./android &
To launch the emulator, from the same folder you need to execute the following command:
./emulator -avd youravdname

It's better to store Android SDK in /opt/ and just run:
$ sudo /opt/android-sdk-linux/tools/android
You can add & at end to run it as background process.

try using the following commands , this should work if you have installed the sdk correctly
Open a terminal
su
input your password
cd Android/SDK/tools (enter)
./emulator -noaudio #android_dev
