 private void gettext ()
{
    new Thread(new Runnable(){
        public void run(){
            ArrayList<String> urls=new ArrayList<String>(); //to read each line
            try {
                mygooglelink="https://drive.google.com/file/d/1zGDm2iEIg632QZyJlM_5FfZXsOy5qsWc/view?usp=sharing";
                URL url = new URL(mygooglelink); //My text file location
                HttpURLConnection conn=(HttpURLConnection) url.openConnection();
                conn.setUseCaches(false);
                conn.setConnectTimeout(1000);
                BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));       
                String str="";
                str = in.readLine(); //Just the first line 
                in.close();
                Log.d("string=",srt);
            } catch (Exception e) {
                Log.d("MyTag",e.toString());
            }
            MainActivity.this.runOnUiThread(new Runnable(){
                public void run(){

                }
            });
