Can not start android emulator from command line

Question

Windows 7, Android Studio 2.3

I has 3 emulators. And all success start from Android Studio.

But I want to start them from command line. So my steps (from command lines):

emulator -list-avds

Success show all my emulators:

Nexus_3_7_API_17_ver_4_2_1
Nexus_3_7_hdpi_API_24_7_0
Nexus_5_96_xxhdpi_API_24_7_0

So I want to start one of them:

emulator -avd Nexus_3_7_API_17_ver_4_2_1

But I get error:

[8648]:ERROR:./android/qt/qt_setup.cpp:28:Qt library not found at ..\emulator\lib64\qt\lib
Could not launch '..\emulator/qemu/windows-x86_64/qemu-system-i386.exe': No such file or directory

I had the exact same issue and I am using a workaround. Let me explain:

There is a 'bug' in the emulator: it is not able to find the relative path

..\emulator\lib64\qt\lib

Incredibly awesome since this is so simple to fix... whatever.

Just cd to c:\path\to\your\android-sdks\emulator, typically something like

cd c:\Users\<YOUR_USER_NAME>\android-sdks\emulator

then, in this directory, run any emulator command you want, for instance your command:

emulator.exe -avd Nexus_3_7_API_17_ver_4_2_1

in your teminal this will look like this:

c:\Users\<YOUR_USER_NAME>\android-sdks\emulator> emulator.exe -avd Nexus_3_7_API_17_ver_4_2_1

and it will work.

on Windows 10, working with .\ before emulator.exe as .\emulator.exe -avd Nexus_3_7_API_17_ver_4_2_1 — Muhammad Shoaib Murtaza, Jul 16 '19 at 15:25

Adding emulator path in Environmental Variables solved my problem. Now, I can run emulator command from anywhere.

You can achieve this by following these steps:

Open 'Advanced System Settings'.
Click 'Environmental Variables'.
Add the following to Path variables in both boxes:

%USERPROFILE%\AppData\Local\Android\Sdk\emulator
Restart Command Prompt.

Note: Your path could be different than the one mentioned above. If this is the case, then you have to search for your emulator path.

Open Command Prompt
go to path of your emulator for ex:

$ cd c:\sdk\tools

run emulator :

$ emulator -avd Nexus_3_7_API_17_ver_4_2_1

Is it possible from any place to run emulator? Without cd c:\sdk\tools – Alexei Apr 26 '17 at 08:00

emulator dependent on libraries in that folder in linux you can use this by add this function to ~/.profile (or ~/.bashrc) : function emulator { cd "$(dirname "$(which emulator)")" && ./emulator "$@"; } – Mortada Jafar Apr 26 '17 at 08:03
I was able to make it work by adding the following to my bashhrc: "function emulator { cd '/Users/locus/Library/Android/sdk/emulator' ./emulator "$@" }" – Brndn Jun 22 '23 at 09:14

For Mac user, similar to Pascal's answer, in Terminal type:

cd /Users/myname/Library/Android/sdk/tools
./emulator -adv mydevicename

For other mac users below might be what's needed.

cd ~/Library/Android/sdk/emulator
./emulator -avd Nexus_S_API_31 -change-locale fr-CA

my error when executing the followings:

emulator -avd Pixel_2_API_28

[4809612736]:ERROR:android/android-emu/android/qt/qt_setup.cpp:28:Qt library not found at ../emulator/lib64/qt/lib
Could not launch '/Users/myname/.android/../emulator/qemu/darwin-x86_64/qemu-system-x86_64': No such file or directory

Open Command Prompt write this emulator -avd avd_name [ {-option [value]} … ]

/Users/janedoe/Library/Android/sdk/tools/emulator -avd Nexus_3_7_API_17_ver_4_2_1 -netdelay none -netspeed full

Of cause I need to specify the full path. But I don't want to do this every time. I want to start emulator from ANY place without full path. – Alexei Apr 26 '17 at 11:01
what do u mean of "from any place" ? – Abubakar Apr 26 '17 at 14:11
please be specific – Abubakar Apr 26 '17 at 14:15
e.g. start emulator when I'm in folder "C:\temp" , or "D:\dev\myProject\" – Alexei Apr 26 '17 at 15:09
alter direcotry – Abubakar Apr 26 '17 at 15:21
I don't want to start emulator like this: "c:\Program Files\android-sdk-windows\emulator -avd Nexus_3_7_API_17_ver_4_2_1". I want to start emulator like this: "emulator -avd Nexus_3_7_API_17_ver_4_2_1" – Alexei Apr 26 '17 at 15:41

Add the following to your ~/.bashhrc or ~/.zshrc, remembering to update the username:

function emulator {
  cd '/Users/locus/Library/Android/sdk/emulator'
  ./emulator "$@"
}

Afterwards do to reload the changes:

source ~/.zshrc

Then, verify it works by running:

emulator -list-avds
