Phone processing power and memory- There are many fast selling and popular low end devices.

Its a phoneAfter all its a mobile phone so think about how will your app handle interruptions (incoming call) & poor network connectivity.

Make Android work for you- Use Intents to use functionalities from other apps.- Use content providers to get information from OS.

It’s a phone

Give back to Android

• Open up intents so that other apps can use it. Connect the apps.

Android TipsJess Anders

Fragment Tips

• Fragment.getActivity() (or null)

• FragmentTransactions after onPause()

• Keep track of state of onCreateView and onDestroyView

Caution posting to Handlers

mHandler.post(new Runnable() { public void run() { if (mIsExited) { return; } updateUI(mNote); }});

Expect the user not to save

• Auto-save in Evernote client

• Food auto-save

• Meal Activity

Analyze the problem and worst case scenarios.

◦Calculations Spreadsheet for Food 1.0

• Determine if you can do the work in Java code

• For Food, we came up with a piece-by-piece

approach with BitmapRegionDecoder (2.3+)

• For the multi-shot camera, we reused this, but then had a fallback of a native library to process

the large photos on older devices.

• Thrift for server-client communication

Android SDK: Authentication

private static final String CONSUMER_KEY = "Your consumer key";private static final String CONSUMER_SECRET = "Your consumer secret";private static final String EVERNOTE_HOST = EvernoteSession.HOST_SANDBOX;private EvernoteSession mEvernoteSession;

@Overridepublic void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main);

mEvernoteSession = EvernoteSession.init(this, CONSUMER_KEY, CONSUMER_SECRET, EVERNOTE_HOST, null);

if (!mEvernoteSession.isLoggedIn()) mEvernoteSession.authenticate(this);}

@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if(requestCode == EvernoteSession.REQUEST_CODE_OAUTH && resultCode == Activity.RESULT_OK) //Success, Update UI when OAuth activity returns result}

Android SDK: Creating a note

/** * This is a network request, call outside of main thread */public void createNote(String title, String content) { Note note = new Note(); note.setTitle(title);

String enmlContent = EvernoteUtil.NOTE_PREFIX + content + EvernoteUtil.NOTE_SUFFIX;

note.setContent(enmlContent); note = mEvernoteSession.createNoteStore().createNote(mEvernoteSession.getAuthToken(), note);}

Intent: Creating a note

public static final String ACTION_NEW_NOTE = "com.evernote.action.CREATE_NEW_NOTE";

public void newNoteWithContent(View view) { String text = "This is a sample text file.\nThis is line two."; String title = "New Note with Content"; Intent intent = new Intent(); intent.setAction(ACTION_NEW_NOTE); // Set the note's title and plaintext content intent.putExtra(Intent.EXTRA_TITLE, title); intent.putExtra(Intent.EXTRA_TEXT, text);

startActivity(intent); }

Intent: Viewing a note

public static final String ACTION_VIEW_NOTE = "com.evernote.action.VIEW_NOTE";

public void viewNote(View view) { String noteGuid = "63781605-3c3d-4e56-90a8-8be5e3ae7eee"; boolean hideTitleBar = true; Intent intent = new Intent(); intent.setAction(ACTION_VIEW_NOTE); intent.putExtra(EXTRA_NOTE_GUID, noteGuid); intent.putExtra(EXTRA_FULL_SCREEN, hideTitleBar); startActivity(intent);}
