How to Tell if a Service Can be Used in My App
<p>I hope the terminology is correct as I am relatively new to Android App development, but...</p>

<p>How can I tell the following:</p>

<p>1) If another App provides a 'service' that my App can use?
2) How to access it?</p>

<p>Here is an example of what I'm talking about.</p>

<p>Suppose I know of an App that provides the locations of restaurants (I think there are a few) and I create an App that Rates Italian Restaurants. A user puts in the name of an Italian Restaurant (into my App) and my App spits out a Review and ALSO uses information provided by the 'Restaurant Locator App' to display to the user WHERE this restaurant is.</p>

<p>My question is: How do I know if the 'Restaurant Locator App' provides this information for my App to use and - IF SO - how do I access it?</p>

<p>Not looking for code examples here - just general explanations.</p>

<p>Thanks!</p>
