Solution

Well , i found a solution for this problem. I don't know what it's wrong with Android Studio but he can't execute the any emulator and the solution for me nowadays is execute the emulator by command,after that you install a emulator using android studio execute the command below because you need to have the emulator, in my case Nexus_5_API_21.

LD_PRELOAD='/usr/lib/x86_64-linux-gnu/libstdc++.so.6' ~/Android/Sdk/tools/emulator -netdelay none -netspeed full -avd Nexus_5_API_21

i don't remeber exactly where i found this solution but i think it's on google forums
