  1. WC2012Programming Mobile Devices Intermediate AppInventor

  2. Impressions so far?

  3. So What is AppInventor Good For? Intro to programming concepts Logical design/critical thinking Intro to Object concepts, event handling and other common areas of difficulty Intro to Mobile App development Starting point on a migration through a whole class in App Development Summer Camps for HS students Other?

  4. Some Interesting Resources • KATE Workshops • https://docs.google.com/document/d/1L7PEy_NdiiRTfIIEADHTBTMYO-ifHIPD-WkzgvabaEk/edit • Vocabulary Builder • Classroom Management

  5. Next Topic : User Response So let’s talk about Quizzing A very Simple Quiz app (1 question) How could we improve this?

  6. Local Storage • “In-App” Storage • We can use Lists for this and they can be static or dynamic • Quiz with a Static List (QuizMe Tutorial) • Assignment – Use this tutorial to make a quiz of your own….

  7. Persistent Storage • On The Phone using TinyDB • Persistent on your phone and tied to App • Can be cleared on phone • Won’t be “persistent” while testing in emulator once you close the emulator • “In the Cloud” using TinyWebDB • Stored in a cloud DB using web services • By default, the TinyWebDB component stores data on a test service provided by App Inventor, limited to 1000 entries • Can create your own web service as well on the appspot.com server provided by Google

  8. Video Tutorials on Storage • http://android.jwtyler.com/?page_id=7 • Other good tutorials here also • Another good tutorial source • https://sites.google.com/site/stevozip/ • Other good resources • http://www.tair.info/

  9. Lets look at a complicated Quiz app • Actually a set of apps • MakeQuiz and TakeQuiz • In the AppInventor Tutorials

  10. Using Communication Tools • Let’s look at a couple of texting applications • TextGroup Tutorial • Uses a static list • TextGroup2 Tutorial • Source available on Wiki • How do I get it and load it? • Uses local persistent storage (i.e. TinyDB) • Assignment – How could you maintain multiple groups?

  11. Automatic Responses • Detect when a text message comes in and send an automatic response • Like your email autoresponder • No Text While Driving Tutorial • Source on Wiki • Try a variation like • Custom responses for particular phone numbers • Custom responses based on location • Variations on a theme… • No Texting While Driving 2 • Reads the message to you so you don’t miss anything • Also on Wiki

  12. Location Services 1 deg of latitude is approx 69.047 miles or 111.12 km 1 deg of longitude is 69.047 x Cos (current lat) • Where’s my Car? • Source on Wiki • Uses location services to record a “remembered” spot and then help you get from current location to remembered spot. • Uses map services as well • Assignment variations • Breadcrumb app that logs all location changes and can show route on map • Hike/Walk/Jog tracker that shows legs of a journey with approx distances and total distance
