- 22. Applications
- 23. Building Blocks ● Activity ● Intent Receiver ● Service ● ContentProvider
- 24. Activity ● A single, focused thing that the user can do ● Provides a screen with which users can interact in order to do something
- 25. Intent Receiver ● ● Handle the broadcast intents
- 26. Service ● Can perform long-running operations in the background and does not provide a user interface ● A component can bind to a service to interact with it
- 27. Content provider ● Enable applications to share data
- 28. Intent ● Passive data structure holding an abstract description of an operation to be performed ● Used to start your activities ● Used to start external applications

- 30. How about my handy Java frameworks?
- 31. The Best Programmers Are Lazy and Dumb ?!?!?
- 33. Helps with activities @NoTitle @Fullscreen @EActivity(R.layout.bookmarks) public class BookmarksToClipboardActivity extends Activity { @ViewById ListView bookmarkList; @ViewById EditText search; @AfterViews void initBookmarkList() { search.setText(??);//..... }
- 34. Helps with events //..... @Click( {R.id.button1, R.id.button2}) void updateBookmarksClicked() { searchAsync(search.getText().toString(),userid); } @ItemClick void bookmarkListItemClicked(Bookmark selectedBookmark) { clipboardManager.setText(selectedBookmark.getUrl()); } //.....
- 35. Helps with preferences @SharedPref public interface MyPrefs { @DefaultString("John") String name(); @DefaultInt(42) int age(); long lastUpdated(); } …............................... @EActivity public class MyActivity extends Activity { @Pref MyPrefs_ myPrefs; }
- 36. Helps with Rest Services @Rest("http://tagonsoft.ro/") public interface CodecampClient { @Get("codecamp.php") @Accept(MediaType.APPLICATION_JSON) Codecamp getEventData(); @Post("feedback.php") void sendFeedback(Feedback feedback); RestTemplate getRestTemplate(); }
- 37. Got ORM? OrmLite @DatabaseTable(tableName = "sessions") public class Session { @DatabaseField(id = true, columnName = "_id") long id; //.... } //.... TableUtils.createTable(connectionSource, Session.class); //.... dbHelper.getSessionDao().create(session); dbHelper.getSessionDao().queryForId(sessionID);
- 38. And it all builds up
- 39. So? ● Android is the world's most popular mobile platform ● Writing Android code can be fun and easy ● developer.android.com is your friend ● You can download example Codecamp app source code from https://bitbucket.org/gdogaru/codecamp_android
