Question

How to call and execute a function without blocking the application android (this is the location function).

I know I must use the thread but I do not know how, I hope to have a code ready.

Answer 1

Use the following to run code on a separate (non-UI) Thread:

new Thread(new Runnable(){
        public void run(){
            //do stuff here
        }
    }).start();

This creates a new Thread (and corresponding Runnable which contains the code to be run inside its run() method ) and starts it — calling the code in the Runnable.

Alternatively, you could look into AsyncTask (more info here) which avoids using Threads directly.
