Incompatible types required java.lang.string found java.lang.object
<p>I'm following <a href="http://examples.javacodegeeks.com/android/android-google-places-autocomplete-api-example/" rel="nofollow">this</a> tutorial to be able to implement Google Places API on a search view. I'm getting the following error on this line:</p>
