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.

Delete both Android SDK Tools and Android SDK PLatform-tools  then download both packages again  Now  create a new emulator and start it  it will work  You might be able to run your old emulators

You cannot start emulator-x86 directory  because it needs to have LD LIBRARY PATH setup specially to find the PC Bios and GPU emulation libraries  that s why  emulator  exists  it modifies the path  then calls emulator-x86    Did you update the first ouput   It looks like  emulator  is still finding    usr local bin emulator-x86

First  check the path you get with which emulator and if you get  usr local share android-sdk tools emulator then remove or rename that emulator  it s an old one  and instead use  usr local share android-sdk emulator emulator which is the new path   If you re using Homebrew and installed with brew cask install android-sdk android-studio then you need to    Verify your  bashrc or  zshrc that you have the correct paths set      Remove  HOME Library Android paths   The new way is to use ANDROID SDK ROOT export ANDROID SDK ROOT   usr local share android-sdk    For good measure  add old paths to be backwards compatible with any scripts or  whatnot  And to hopefully decrease confusion  export ANDROID HOME  ANDROID SDK ROOT export ANDROID NDK HOME  ANDROID SDK ROOT ndk-bundle    Then restart your terminal shell  and check your paths are as you expect them   set   grep ANDROID Finally  with correct paths set  you typically need to install the ndk and some tools   sdkmanager  ndk-bundle   cmake 3 10 2 4988404   lldb 3 1   and check the list  for other pieces like this sdkmanager --list   I also closed Android Studio  removed the old Android Sdk folder under my  HOME folder  and restarted Studio  and when it asked where my Sdk had gone  I pasted the Sdk path   usr local share android-sdk

The issue stems from SDK changes  since emulator now has it s own directory  I didn t notice  nor care  to run an outdated emulator  while it still worked     This is a stalled SDK migration  When running with the -verbose switch  emulator -avd Nexus 6 API R -verbose  One can see where it starts to panic  emulator try dir C  Android tools emulator Looking for emulator-x86 to emulate  x86  CPU emulator Probing program  C  Android tools emulator-x86 exe PANIC  Missing emulator engine program for  x86  CPU   But there is no emulator-x86 exe available and the actual emulator resides in directory emulator  After uninstalling  quot SDK Tools quot   while trying to reinstall them   that one entry unexpectedly vanished from the list  leaving an empty tools directory  which may be deleted and removed from PATH  Using x86 64 emulation is not required nor suggested  as this will run the stalled version of the emulator   Adapting to the SDK path changes by uninstalling  quot SDK Tools quot  is rather  quot the answer quot   One probably could just replace tools with emulator on PATH  but this leaves clutter behind   For comparison  the actual startup sequence of version 30 3 5 0 should look about like this  emulator  Android emulator version 30 3 5 0  build id 7033400   CL N A  emulator  Found AVD name  Nexus 6 API R  emulator  Found AVD target architecture  arm emulator  argv 0    emulator exe   program directory   C  Android emulator   And if there may be follow up errors alike  PANIC  Broken AVD system path  Check your ANDROID SDK ROOT value  This means that the system image path inside the   ini may be wrongful It helps to download the x86 system image and then create a new emulator
