My problem is that i cannot run the android studio emulator, I had searched to many articles, and i had found here that i had to set Software for Emulated Performance Graphics option, in the AVD settings, However i found that it's disabled by default.

I had reached this issue tracker too, but it's too long and misleading, and their variables may doesn't belong to my case.

So, my Event log text with the red color return the following error lines :

12:02 PM    Emulator: emulator: ERROR: AdbHostServer.cpp:102: Unable to connect t

Excuse me, can any body help, your help is mainly appreciated.

edit #1 Please note, that i use Windows as my Operating system.

I had found that article which is similar to this one in this part

$ sudo nano /etc/bash.bashrc
$ export ANDROID_HOME=${HOME}/Android/Sdk
$ export PATH=${PATH}:${ANDROID_HOME}/emulator
at reference [one][3]  and this part 

30 EDIT

fixed "ANDROID_EMULATOR_USE_SYSTEM_LIBS" error, turns out I improbably assigned ANDROID_HOME, reassigned the value "export ANDROID_HOME=/[installation location]/SDK", then "export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools".
My bad :(, now time to start my first android application ever :D, thanks all.

Really, i still don't know whether the solution is based on the Android Home in the environment variables, but i would like some one help me. Thanks
