After attempting to start the emulator for AVD 'hello', an error was displayed on the Logcat:
The emulator encountered a WARNING stating that it could not initialize OpenglES emulation, resorting to using software renderer. The RenderServer creation also failed to listen, with the additional error message indicating that the emulator window was out of view and had to be re-centered. It appears that there are too many instances of emulators currently running on this machine, resulting in an abortion of the process.
