ERROR:./android/qt/qt_setup.cpp:28:Qt library not found at

[Stubbs]

I'm getting the following error when trying to run the Android (AVD) simulator, for API 22 or 25:

[140735755441088]:ERROR:./android/qt/qt_setup.cpp:28:Qt library not found at ../emulator/lib64/qt/lib
Could not launch '../emulator/qemu/darwin-x86_64/qemu-system-i386': No such file or directory

I've re-installed the SDK a few times as suggested on Stack Overflow, but no joy.

Is there a Deco way to fix this?

starting emulator ... from $ANDROID_HOME/tools can be used as a workaround

I've experienced the same error on a linux system.
The problem was the ANDROID_HOME environment variable was not settled permanently.
On Ubuntu 16.04 to have the ANDROID_HOME settled on system boot you have to export it inside the '.profile' file.

Anyone figured out the issue, for now doing the workaround that @zoechi Gunter suggested, but can't get an android SDK to emulate from AVD (inside android sdk) or anything besides doing:

cd $ANDROID_HOME/tools then emulator --avd @whatever_name_it_is

Craziness :(

Also, when launching from cmd line you cannot close the command line window.... ufff...

Have the same issue without deco-ide.

Maybe your environment setups are not correct. Can you show your bash_profile's content?

As of 12/25/2017. I see that you should only add below into the path to be able to launch emulator

C:\Users\Ram\AppData\Local\Android\Sdk\platform-tools C:\Users\Ram\AppData\Local\Android\Sdk\emulator.

This is after installing Android Studio 3.0 and higher. I see that C:\Users\Ram\AppData\Local\Android\Sdk\emulator

has same thing as
C:\Users\Ram\AppData\Local\Android\Sdk\tools

But tools folder is missing some files, so remove tools folder from path.

You can use below emulator commands to launch emulator from command prompt:
emulator -list-avds
emulator @Pixel_2_XL_API_26 - Based on the avd that you have setup

I manage to solve this error. In my system varible i need to set ANDROID_HOME

For my User variable i need
both these path

C:\Users\tonyhudson\AppData\Local\Android\Sdk\platform-tools
C:\Users\tonyhudson\AppData\Local\Android\Sdk\emulator

Remember to delete C:\Users\tonyhudson\AppData\Local\Android\Sdk\tools because it will cause the error

[ngohungphuc]

@MarkPieszak @zoechi @Stubbs please check my answer it could help you guys

[firdausious]

@ngohungphuc Nice.. also work on Mac... 👍

[ngohungphuc]

@firdausious your welcome

[zszep]

@ngohungphuc Deleting C:\Users\tonyhudson\AppData\Local\Android\Sdk\tools from the path did the trick.

[jaimeohm]

@ngohungphuc Deleting tools from the path and adding emulator to the path did the trick.

I confirm the above solution on ubuntu 18.04

[adnanahmady]

it can be because of your adding orders for example in Linux you must watch the way you put your paths to the $PATH environment variable, for example,
YOUR_PATH:$PATH
means descending order of adding your paths so you must add your path for emulator folder as the last parameter/line like this:
YOUR_SDK_PATH/tools:$PATH
YOUR_SDK_PATH/emulator:$PATH
and when you use this pattern $PATH:YOUR_PATH it will be like this:
$PATH:YOUR_SDK_PATH/emulator
$PATH:YOUR_SDK_PATH/tools

[dzvid]

It worked for me after I updated my android sdk and fixed my env vars in ~/.profile:

export ANDROID_HOME=~/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

then reloaded it with: source ~/.profile

Even I start through command prompt i get the same issue in WINDOWS 10

[12552]:ERROR:android/android-emu/android/qt/qt_setup.cpp:28:Qt library not found at ..\emulator\lib64\qt\lib
Could not launch 'C:\Users\Downloads\android-sdk\tools\..\emulator\qemu\windows-x86_64\qemu-system-i386.exe': No such file or directory

I have added the ANDROID HOME and also mapped the tools\emulator in the path section.

When I try to launch the emulator from Command line I get this issue.

I have declared the Environmental variable as below

Even I remove the tools path from the environmental variable does not work and thrown the same exception

I have the emulator in this path only
C:\Users\XYZ\Downloads\android-sdk\tools and not on the C:\Users\XYZ\Downloads\android-sdk

[ashokkumarg]

I just fixed it. The reason is I have not agreed to licenses and that does not create the %ANDROID_HOME%\emulator path.

use sudo before running from $ANDROID_HOME`

[mslonnyweblab]

Ola pessoal, consegui resolver removendo das variaveis de ambiente ANDROID_HOME\tools e ANDROID_HOME\tools\bin.
