How do i send my location online in android studio - android-studio

Question

I'm a beginner to android studio. I'm trying to build an my project app that can send my location to another client with just one click. i.e through online server.
At first I'm trying to test if my button gets the latitude and longitude value from the LocationListener.
below is my mainActivity
