How do I go about using a users location when they are in a certain place? The place would trigger an action based on location
<p>I'm trying to create an app for android with little experience programming. I want to use a phones gps to determine a place on google maps then cause an action to happen. The action would be based on the location and I'd also like to have the user designate locations to cause an action. </p>

<p>If there are any resources or websites you can point me to I would really appreciate it. </p>

<p>I'm currently only using android studio, is there anything else I need?</p>
