Challenges
•Difficulty accessing the internet
Solution: Add the following line of code to the manifest.xml file:
<manifest xlmns:android...> ...
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>
• Proper documentation and extensive tutorials was missing
Solution: A lot of trial and error. Eventually figured out how code worked
• Database presented challenges . It worked, but we have difficulty having it work together with the rest of
