Why emulator or Genymotion is unable to run my app properly?

Question

I am using Genymotion for personal use to test my apps.
However, the emulator opens up, displays everything fine.
As soon as I run my app, it hangs or crashes.Same is happening when I use default android emulator.
Also its taking quite too long to open my default emulator.
I checked HAX on console and it is running fine.
My system RAM is 8Gb.
It appears to me some memory like issue but cannot figure it out exactly.

I had the same problem with ...

The solution that worked for me with x86 emulator was to update HAXM with the last version and to restart my computer.

The root cause was a missing video driver (the vanilla Microsoft one wasn't enough). I was working with a cobbled-together frankenbox and found it useful to follow the instructions on finding the right driver here:
