My Android Studio IDE is missing the tool window "Emulator" in View -> Tool Windows though the "Launch in a tool window" option is checked in File -> Settings -> Tools -> Emulator.
I don't know what changed this but it used to work properly.
I can't seem to find anyone with the same issue.
Finally, this solved the problem in my case.
Go to File-> Project Structure->Modules and add Android and Apply.
Automatically displays Emulator Menu in Right Panel!
First , you should check the following things:
1- Install Java JDK .
2- add Path(JAVA_HOME) to environment variables ( Windows operating system) .
3- Install a Gradle 4-add Path(GRADLE_HOME) to the environment variables .
5- Install the SDK Android
6- add Path (ANDROID_HOME) to the environment variables (ANDROID_HOME).
