Q:

Is it safe to end process emulator-arm.exe (Android emulator) instead of closing it by the close button

I have noticed that closing the Android emulator by close button (the top right button) takes a lot of time.  
Ending process emulator-arm.exe (through task manager) closes it instantly.
When I open the Android emulator next time, there seems to be no data loss. 
So is it safe to end process emulator-arm.exe all time?

A:

It probably takes long to close because it's saving a snapshot to speed up next startup.
If you are not using the sanpshots you can run the emulator with -no-snapstorage option to disable them.
