Example 1: java do something after x seconds without stopping everything else

new java.util.Timer().schedule( 
        new java.util.TimerTask() {
            @Override
            public void run() {
                // your code here

  //create runnable for delay
       mToastRunnable = new Runnable() {
            @Override
            public void run() {
                Toast.makeText(MainActivity.this, "This is a delayed toast", Toast.LENGTH_SHORT).show();
                mHandler.postDelayed(this, 3000000);
                getlocation();
            }
        };
