Emulator-5554 disconnected! Cancelling 'activity launch'! Tried to resolve with cmd commands but still not working

What I did is go to the Android Virtual Manager (AVD) and edit Memory Options: like adjusted Ram from 15 to 30 and VM Heap from 16 to 32. Since then the "emulator: 5554 diconnected! Cancelling ..." never scared me till I shut it down. It works for me, though.

Failed to install HelloAndroid.apk on device 'emulator-5554!

wait for the emulator to setup completely and then test your app. Also, I would leave you AVD open so you dont have to wait so long everytime you run your application.

When it shows the red writing, don't close anything - leave it there and then press the run button again. Worked like a charm.
