Cannot deploy app to emulator in Android Studio - "unknown avd" -


i made simple hello world app deploy emulator in android studio.

this used work before same project (i installed necessary packages) time random reason, in run options when select "target: emulator", under "prefer android virtual device" following in red: "unknown avd".

i've googled around , answers vary. answer seems make sense is:

you have install intel image library , google api desired api. go sdk manager , check intel system images installed or not if not have installed install google api library.

however don't have these "intel image libraries" , "google api" options in sdk manager. these shorthand aliases other names in options?

any ideas on how emulator , running?

a bit of information on environment:

  • android studio 2.3.3
  • windows 7 professional 64 bit
  • gradle version: 3.3
  • selected sdk platform package: android 7.1.1 (nougat)/ api level 25
    revision 3
  • virtual device: nexus 5x api 25

try kill adb server , restart it.

locate adb binary (linux/osx) or adb.exe (windows) , do:

adb kill-server

adb start-server

this should fix problem

even if problem still not solved restart emulator.
