- Take photos for a meal entry.
- Integrate built-in camera/photo-taking abilities of android device
- See "Photo Review Screen".
- Write notes for a meal entry.
- The Photo Review Screen should have an input text field
- See "Photo Review Screen".
- Add a new meal entry and save it to local storage.
- Entries should save to the android device's local storage.
- Manage local data storage.
- Local data storage could be managed by using SQLite databases along with existing APIs for Android's framework related to local storage.
- Display previous entries in a scrollable list.
- Integrate a "ListView".
- Have the click of a particular item in the list take one to the review screen.
- See "Previously Submitted Pictures".
- Backup application data with android backup service.
- Although users will be able to use Google Drive (see requirement 7) to share their meal data with a dietitian, a background backup service is still desirable. Pushing to Google Drive will not be automatic, whereas a backup service will be. If a user switches devices, he or she will want to easily restore the app’s data.
- Push a range of meal entries to a shared Google Drive folder for review by a dietitian.
- This can be accomplished by using Google Play Services and Google APIs that allow use of popular Google services, including Google Drive.
- There are existing apps that already perform this task such as FolderSync and GDriveSync, so those can be used as a helpful guide.
- Present meals to the dietitian in a meaningful way (i.e., not requiring the dietitian to browse through a raw directory structure to view the pictures and notes).
- Perhaps the app could generate HTML files (a sort of local website) that allow the dietitian to navigate and view the user's meals in a web browser.
- Develop other activities in menu bar (DrawerLayout) such as My Account, Reminders, and Useful Dietary Info.
- Information that would need to be saved for future use such as that used in "My Account" or "Reminders" could be saved in an SQLite database and retrieved when needed.
- Add logic to determine dimensions/contents of food in a given photo.
- Once a method of determining a correct and consistent scale for foods in photos is created, we could use information of known foods in order to provide accurate results of food’s physical dimensions/properties. This information could be based on the scale of the food in relation to the photo and what scale it “should” be.
