place following code in code:
runnable mstatuschecker = new runnable() { @override public void run() { try { <call location fetching method here || call location.get... methods here> } { mhandler.postdelayed(mstatuschecker, minterval); // set minterval = 300000 } } }; void startrepeatingtask() { mstatuschecker.run(); } void stoprepeatingtask() { mhandler.removecallbacks(mstatuschecker); }
