emulator -avd does not launch the device

on Ubuntu 16.04 I have installed AndroidStudio and via its AVD manager GUI did create tow new devices. now on Terminal when I type emulator -list-avds it lists the devices correctly, but when run emulator -avd <name> I face errors:
[139684796983104]:ERROR:android/android-emu/android/qt/qt_setup.cpp:28:Qt library not found at ../emulator/lib64/qt/lib
Could not launch '/home/amir/../emulator/qemu/linux-x86_64/qemu-system-i386': No such file or directory
How should I solve it?

both in Windows 10 and Ubuntu I was facing the same problem. the simple solution is that I had to go to the directory of tools then execute the command. for instance in windows.
$ cd C:\Users\user-name\AppData\Local\Android\sdk\tools
emulator -avd <deviceName>
also it is good to mention I wanted that for React-Native development, and Expo XDE saved me

Can't run Cordova android app in Emulator (Ionic app)

I have created an android emulator but I am not able to get it work and run and android app with cordova. Using Mac.
When I run:
/avdmanager list avd
I get:
Name: AVD16
Device: wear_round_chin_320_290 (Google)
Path: /var/root/.android/avd/AVD16.avd
Target: Google APIs (Google Inc.)
Based on: Android 4.1 (Jelly Bean) Tag/ABI: google_apis/x86
Sdcard: 100M
So, my AVD emulator exists, but when I run in my project folder:
cordova emulate --target=AVD16 android
I get:
BUILD SUCCESSFUL
Total time: 6.54 secs
Built the following apk(s):
/Users/francisco/{PROJECT_FOLDER}/platforms/android/build/outputs/apk/android-debug.apk
ANDROID_HOME=/Users/francisco/Library/Android/sdk
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home
Waiting for emulator to start...
PANIC: Unknown AVD name [AVD16], use -list-avds to see valid list.
HOME is defined but there is no file AVD16.ini in $HOME/.android/avd
(Note: Directories are searched in the order $ANDROID_AVD_HOME, $ANDROID_SDK_HOME/avd, and $HOME/.android/avd)
And nothing happens, emulator is not opened, just gets stoped forever.
What could I do to run this app on that emulator?

I'm trying to run my first Ionic app but i'm getting this error where it does not find my phone and does not find the emulator to run either

$ ionic run android
result:
No target specified and no devices found, deploying to emulator
Error: No emulator images (avds) found.
1. Download desired System Image by running: "C:\Android\tools\android.bat" sdk
2. Create an AVD by running: "C:\Android\tools\android.bat" avd HINT: For a faster emulator, use an Intel System Image and install the HAXM
device driver

To run ionic run android command, you should have android emulator installed. so install and run the command
If you still want to build app, you can connect your mobile to system, enable developer option in settings, then run the same command it will install into your mobile.
To enable developer option in your mobile: go to setting,developer option,enable checkbox USB debugging.

Reason for this error is available emulator API version does not match with android platform version of your project. Try to add appropriate emulator using avdmanager and try to rerun.

Nativescript - native emulator error when run android --emulator

I receive the following error when I run android --emulator on my cmd;
Cannot run your app in the native emulator. Increase the timeout of the operation with the --timeout option or try to restart your adb server with 'adb kill-server' command. Alternatively, run the Android Virtual Device manager and increase the allocated RAM for the virtual device.
I've opened it with administrator rights and ran all the tutorials on the website.
I'm now stuck at this point and haven't been able to find the solution.
I've also tried tns run android --emulator --timeout -0 and waited for an hour without result.
What can i do to get the emulator running?

I had the same problem, I solved by opening avd manager and try starting the virtual device(emulator) you created. If the emulator doesnt launches, you will get an error in the console.
For me I had to install the intel HAXM, for launching the emulator

You just need to open your Android Virtual Device Manager and download
the latest emulator. Then run your application again.It will work.

tns run android
Runs the Emulator and then run the app on it.
Sometimes both process can't happen at once, admin access in Linux can be such case.
try starting the Emulator first then the app.
emulator -avd avd_name [ {-option [value]} … ]
for example:
sudo $ANDROID_HOME/emulator/emulator -avd test -netdelay none -netspeed full
'sudo' is important for Linux users.
then use this to start the app.
tns run android

Error when running Meteor 1.2 Android / Cordova

I keep getting the following error when I run meteor run android -- verbose
ERROR : No emulator images (avds) found.
1. Download desired System Image by running: /Users/tinzors/Library/Android/sdk/tools/android sdk
2. Create an AVD by running: /Users/tinzors/Library/Android/sdk/tools/android avd
HINT: For a faster emulator, use an Intel System Image and install the HAXM device driver
=> Errors executing Cordova commands:
While running Cordova app for platform Android with options --emulator:
Error: Command failed: /Users/tinzors/Documents/petrocon/.meteor/local/cordova-build/platforms/android/cordova/run --emulator
Anyone getting this too and/or know of a fix?

You don't have any virtual devices set up. You can set one up pretty easily in Android Studio.
Tools->Android->Android AVD Manager.
Or if you have an android device you and have developer options enabled on your phone you can run this and it will install right on your phone:
meteor run android-device
