Use the week six tutorial project as a guide for this section

VenueFetchr : FetchItems()
· Remove the 8 lines of the Uri builder as we do not need to append parameters
· Simply set the URL string to the specified URL
VenueFetchr : ParseItems()
Note that this method returns the results by reference. We only want to return a single venue rather than a list of gallery items
· Change the method parameters to suit
· Remove the loop and the JSONA
ay variable (as we only have one venue to decode)
· Set the venue object attributes from the JSONObject
Using week 7 as a guide
· Add a FetchItemsTask (AsyncTask) to your main activity

Android Manifest.xml
Using the Week 7 project and tutorial document as a guide
· Add the necessary network permissions
· Remember that if you run it before asking permission you will need to uninstall the app and run it again
There is one additional permission you need to add otherwise Android will not access a non https domain.
· Add the following at the end of the application tag (within the tag not after it)

3. Google Maps
Add a new Google Maps activity to the project
Use the week 10 tutorial project as a guide to complete the following.

· Add Google play-services to your gradle file as per the tutorial document

Passing the Venue
