Notes

Here are some various issues and challenges I encountered while building the app.

  • Git couldn't be installed manually due to a network error, I had to download a packaged version
  • The simulator wouldn't start until I approved through the Santa system
  • The FileUtils module was being imported incorrectly. Android Studio automatically imported a built-in class called FileUtils when I needed to import the one from Apache Commons. I couldn't figure out why the readLines() function could not be found until I realized that Android Studio imported the wrong class.
  • I had to search the Android documentation for the right information in order to implement the Alert Dialog feature.
