An open-source space trivia app for Android.

Written by Dan Ruscoe (http://ruscoe.org/)

• Android SDK
• Android 2.2 platform
• OpenCSV 2.3

• Import the Space Trivia project into Eclipse.
• Download and install the OpenCSV library (Installing the OpenCSV Library in Eclipse.)
• Build the project as an Android application.

Trivia categories and questions can be found in CSV files within the /res/raw directory.

• Download OpenCSV 2.3
• Extract the archive and locate the file named opencsv-2.3.jar, in the 'deploy' directory.
• Open the Space Trivia project in Eclipse.
• Create a new folder named libs in the root of the Space Trivia project.
• Copy opencsv-2.3.jar into the newly created libs folder.
• From the main menu, select Project then Clean... and clean the project.

Categories and questions are contained in .csv files. To edit the files:

• In the Space Trivia project, navigate to the res/raw directory.

• To add a new question to an existing category, open the .csv file named after that category and add a new line. See Question CSV Data Format.

• To add a new category, open categories_data.csv and add a new line. See Category CSV Data Format.

• To add questions for a new category:

  • Create a new file in the res/raw directory. The naming convention is: questions_my_category.csv
  • Populate the new file with CSV-formatted question data. See Question CSV Data Format.
  • Open src/org/ruscoe/spacetrivia/dao/TriviaDAO.java.
  • Locate the onCreate method and look for the following code:

  importQuestionsData(db, R.raw.questions_space_exploration);
  importQuestionsData(db, R.raw.questions_earth_moon);
  importQuestionsData(db, R.raw.questions_solar_system);

  • Add a line below that section of code, similar to this:

  importQuestionsData(db, R.raw.questions_my_category);

  Note that the resource ID (R.raw.*) must match the name of the question data file you created, minus the .csv extension.

  • On your device, clear the application data (or uninstall) and rebuild the application from Eclipse.
  • Your new category / question data should now appear in the application.
