The Android SDK includes a mobile device emulator — a virtual mobile device that runs on your computer. The emulator lets you develop and test Android applications without using a physical device.
And moreover, Android Emulator Helps us to Run Whatsapp on PC.

What is "$" in Shell scripts

I do keep on getting confused when it comes to shell script with "$" sign.
So finally I thought I should jot it down somewhere.


$#  implies number of Arguments provided
E.g. if [[ $# -ne 2 ]]
It means, if the number of arguments passed are less then 2

$? tells the exit status of the last executed command

$@   is all of the parameters passed to the script. For instance, if you call ./someScript.sh foo barthen $@ will be equal to foo bar.
Also, $@ = $*


$1 implies the first argument passed

$2 imples the second argument passed.

And so on...
