  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/
