I am trying to run an app from Android Studio but the AVD does not start. It hangs on 'Waiting for target device to come online' although the emulator loading part finishes (the emulator does not open but the progress bar completes).
Output from terminal:

I am running on Ubuntu 17.04 and Android Studio 2.3.3
I searched for similar issues and tried to enable adb integration as suggested, with no success.
Open Android Studio with a valid studio project (if you don't have one, simply create one empty). After you've your project open, go to Tools => Android => AVD Manager . Note that this menu does not appear if you don't have a valid Android Studio project open.
You can install Android Studio on Ubuntu 22.04 using either the android-studio repository or Snap. In both cases you need to install JDK first which can be done using the command $ sudo apt install openjdk-11-jdk.
If you're using a 64-bit version of Linux, make sure you first install the required libraries for 64-bit machines. To launch Android Studio, open a terminal, navigate to the android-studio/bin/ directory, and execute studio.sh . Select whether you want to import previous Android Studio settings or not, then click OK.
Had the same problem this, version on ubuntu and android studio 2.3.3, 1 ways i did which helped me, i search the for and finally found the solutions on stackoverflow The way is to locate lib64 folder since i am running ubuntu 64 bit. In my case, its located under ~/Android/Sdk/emulator/lib64 and run the commands terminal :
//First write the following command in terminal
$ sudo apt-get install lib64stdc++6:i386
$ sudo apt-get install mesa-utils
//Navigate to the ~/Android/Sdk/emulator/lib64 folder
$ mv libstdc++/ libstdc++.bak
$ ln -s /usr/lib64/libstdc++.so.6 libstdc++
