Challenges

4/30/2010

•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 missingSolution: 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 the code.

Solution: Removed database and displayed RSS content directly from website

• Some tutorials were for older API versionSolution: Seeked help from sites and forums

•Works 50% of the time Solution: Next semester

•Memory Leak test?Performance => how long before battery drains Solution: next semester
