Emulator: emulator: ERROR: AdbHostServer.cpp:102: Unable to connect to adb daemon on port: 5037

Question

I am stuck a whole afternoon trying to run again my small Android/Kotlin application in Android Studio. The message pasted on this question topic suddenly nocked me down.

Answer 1

1. emulator -list-avds
2. adb start-server 
3. emulator -avd 

if you see PANIC: Missing emulator engine program for 'x86' CPU.

then you can try

1. emulator -list-avds
2. adb start-server
3. $ANDROID_HOME/emulator/emulator @name_device

for cold boot use flags -no-snapshot and -no-snapshot-load
