Android Emulator Error Message: "PANIC: Missing emulator engine program for 'x86' CPUS."

I am trying to run a Android Emulator by using AVD Manager. this is my avd: http://image-upload.de/image/fnx79V/52b0d050ee.png

and this is what happens by starting:

http://image-upload.de/image/vGpQfa/e912d83939.png

I have a Macbook Pro Retina. Installed the Haxm driver direct from intel page.

No emulator is working. All get the same "error" message.

Running Command (This error was when i used Homebrew for installing Android-sdk and Android-platform-tools | anyone who get the same problem should remove this or look where the conflict is)

export ANDROID_EMULATOR_DEBUG=1 test20

After I fixed the problem with Homebrew:

I tried a bit around and found this:

For all who has the same problem, maybe these steps help:

Run your Emulator in Debug mode:

export ANDROID_EMULATOR_DEBUG=1 emulatorName

If there is a path that look strange check for other installations like Homebrew and remove the conflict (uninstall one)

When the library is missing you need to export the variable:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ANDROID_HOME/tools/lib

And when error "qemu: could not load PC BIOS 'bios.bin'" appears, one fix is to run the emulator with the full path:

/Applications/Android\ Studio.app/sdk/tools/emulator64-x86 -avd test20
In your case it is maybe a other path.

If you are using macOS, add both Android SDK emulator and tools directories to the path:

Step 1: In my case the order was important, first emulator and then tools.

export ANDROID_SDK=$HOME/Library/Android/sdk
export PATH=$ANDROID_SDK/emulator:$ANDROID_SDK/tools:$PATH

Step 2: Reload you .bash_profile Or .bashrc depending on OS

Step 3: Get list of emulators available: $emulator -list-avds

Step 4: Launch emulator from the command line and Replace avd with the name of your emulator $emulator @avd

Don't forget to add the @ symbol.

This was tested with macOS High Sierra 10.13.4 and Android Studio 3.1.2.

I had this issue after upgrading Android Studio to 3.2 and even upgrade some SDK-Packages.

The cause was that the path to emulator had changed, so don't use ...../Android/Sdk/tools/emulator but instead ....../Android/Sdk/emulator/emulator.

The following work-around to start emulator-x86 worked for me:

cd $SDK/tools; 
ln -s emulator64-x86 emulator-x86

Or on Windows open Command Prompt (Admin)

cd %ANDROID_SDK_ROOT%\tools
mklink emulator64-x86.exe emulator-x86.exe

And now the emulator will start from the SDK manager.

Note: Emulators islocated in emulators folder in more recent versions.
