I installed android studio and tried to run easy projects.
But I caught strange error message:
Waiting for device. /usr/local/idea/android-studio/sdk
The same problem but different solution, I modified my Virtual Device, I changed Memory option and Internal Storage, and it works fine. RAM:512 , VM HEap: 192, Internal Storage=200, SD Card Size: 200 for Device Nexus 4 android 4.2.2.
