Location Service
<p>i create a service class that extends location listener. whenever the location changed i has to do some work. </p>

<p>Firstly i do my work in "onLocationChanged" function but here problem is that when location changes and "onLocationChanged" called then the work i do in "onLocationChanged" repeat continously. </p>

<p>Then i set set latitude and longitude in "onLocationChanged" function and call another function in timer, but within timer, my function cannot be called and give error "Can't create handler inside thread that has not called looper.prepare".</p>

<p>Any one can help me please that how can i call function repeatdly after some specific time within service.</p>
