How to fix it? I read topics with similar errors but it doesn't help me.

Answer 1

In my case (Ubuntu 16.10 64-bit, Android Studio 2.3) libs were located in another place. So commands are:

/home/myusername/Android/Sdk/emulator/lib64/libstdc++

➜  libstdc++ ll
total 9,3M
-rwxr-xr-x 1 myusername myusername 4,6M мар 21 00:09 libstdc++.so.6
-rwxr-xr-x 1 myusername myusername 4,6M мар 21 00:09 libstdc++.so.6.0.18

➜  libstdc++ mv libstdc++.so.6 libstdc++.so.6.bak
➜  libstdc++ mv libstdc++.so.6.0.18 libstdc++.so.6.0.18.bak
➜  libstdc++ ln -s /usr/lib32/libstdc++.so.6 /home/myusername/Android/Sdk/emulator/lib64/libstdc++ 
➜  libstdc++ ln -s /usr/lib32/libstdc++.so.6.0.22 /home/myusername/Android/Sdk/emulator/lib64/libstdc++ 

➜  libstdc++ ll
total 9,3M
lrwxrwxrwx 1 myusername myusername   25 мар 29 13:18 libstdc++.so.6 -> /usr/lib32/libstdc++.so.6
-rwxr-xr-x 1 myusername myusername 4,6M мар 21 00:09 libstdc++.so.6.0.18.bak
lrwxrwxrwx 1 myusername myusername   30 мар 29 13:19 libstdc++.so.6.0.22 -> /usr/lib32/libstdc++.so.6.0.22
-rwxr-xr-x 1 myusername myusername 4,6M мар 21 00:09 libstdc++.so.6.bak

And now emulator is launched from AVD manager normally.
