Android emulator shows nothing but blank screen

Question

I am a complete nOOb to Android programming and trying my hands at it for the first time by going through the tutorials. The problem is that I have created multiple emulator

Answer 1

I had the same problem on Macbook pro mid 2012 model with 4 GB RAM and intel core i5 processor, deleted the AVD and created new AVD.
While creating new AVD in the advanced options -->hardware configurations set memory as 512 MB and selected Use Host GPU option.
On launching AVD received the error with some package, was prompted for auto update of this package and worked for me with charm after that.
