22001100 MMoobbiillee MMeeddiiaa CCoonnssuummppttiioonn Mobile Media Usage More Common in U.S. than Europe Throughout the past year, mobile media adoption has continued to grow, as consumers are increasingly turning to their mobiles for many other uses beyond just talking or even texting. Since December 2009 the number of mobile media users has grown significantly in the U.S. as well as across the EU5. 109 million U.S. mobile subscribers (46.7 percent of the total audience) accessed mobile media (browsed, accessed applications or downloaded content or accessed the mobile Internet via SMS) in December 2010, up 7.6 percentage points versus year ago. Europeans displayed a similar adoption rate with 41.1 percent of mobile users accessing mobile media in December 2010 compared to just 35.3 percent in December 2009.

•  Eclipse Android Development •  Development, Tests, Debug •  Export and signature of APKs •  Limited modularity •  Eclipse-‐based build process •  No release process (export wizard)

•  Apache Ant •  Compila=on, Test, Packaging •  Release •  Dependencies management •  Hard to maintain – Scalability – Recursion •  Can quickly differ from standard builds

StAnD


•  Let’s ra#onalize Android development •  Support Android applica=on produc=on from development to delivery

•  Simplifica#on of the development model •  Bootstrap a project in less than 1 minute •  Improve the logging system (Androlog) •  Injec=on framework (Roboject)

•  Reliable build and sophis#cated branding •  Maven-‐based build system (maven-‐android-‐plugin) •  Advanced modularity and composi=on (rindirect)

•  Improve quality and feedback •  Integra=on and UI tests (Marvin) •  Con=nuous integra=on (Android plugin for Jenkins) •  Complete crash report (Androlog)

Androlog

Androlog is a configurable log facade for Android

•  Per-‐logger level configura#on •  Log disabled on end-‐user devices •  Can be enabled by developers to reproduce issues

•  Repor#ng •  Crashes can be reported by mail or a portal •  Device info •  Log •  Complete stack traces

•  Makes logging a lot easier •  Faster bug fixes

Maven-‐Android-‐Plugin

Reliable build system

•  Same build on all machines •  Conven=on over configura=on •  Con=nuous integra=on support •  Dependency management •  Modularity / Branding

•  Release process •  Create marketplace-‐ready APK

•  Archetypes •  Quickstart, with-‐test, release, stand

•  More reliable •  More maintainable •  Release process


Android plugin for Jenkins / Hudson

Tests Android applica#ons con#nuously on several plaVorms

•  1.6 to 3.1 •  A lot of devices are available •  Huge Fragmenta=on (1.6)

•  Tests executed on 25 devices •  Covering the most common devices •  Emulator configura=ons

•  More reliable applica#ons •  Less surprises especially when using internals


Marvin – Simplify Integra#on Tests

Instrumenta#on tests are … really annoying to write !

•  Android instrumenta=on tests •  A lot of asynchronocity •  Tests don’t easily navigate across ac=vi=es •  UI Tests are big burdens

•  Marvin simplifies test wri=ng •  A layer on the top of instrumenta=on tests •  A set of hamcrest matchers •  Integrated into the build process

•  Reduce the amount of code required to write tests •  Support complex workflows •  More reliable applica#ons


public void testLogin() throws Exception {! Instrumentation instr = getInstrumentation();!! ActivityMonitor monitor =

!instr.addMonitor(MainActivity.class.getName(), null, !false);!

Intent intent = new Intent(Intent.ACTION_MAIN);! intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);! intent.setClassName(instr.getTargetContext(), !

!LoginActivity.class.getName());! instr.startActivitySync(intent);! instr.waitForIdleSync();! instr.sendStringSync(“clement");! instr.sendKeyDownUpSync(KeyEvent.KEYCODE_DPAD_DOWN);! instr.sendStringSync(“magic");! instr.sendKeyDownUpSync(KeyEvent.KEYCODE_DPAD_DOWN);! instr.sendKeyDownUpSync(KeyEvent.KEYCODE_DPAD_CENTER);!! Activity mainActivity =

!instr.waitForMonitorWithTimeout(monitor, 30000);! assertNotNull(mainActivity);!}!

public void testLogin() throws Exception {! LoginActivity loginActivity =

!startActivity(LoginActivity.class);! assertThat(loginActivity)

!.sendString(”clement") !.keyDownUp(KeyEvent.KEYCODE_DPAD_DOWN) !.sendString(”magic") !.keyDownUp(KeyEvent.KEYCODE_DPAD_DOWN) !.keyDownUp(KeyEvent.KEYCODE_DPAD_CENTER) !.startsActivity(MainActivity.class);!

}!

Version 4

•  More brandings •  Quality++ •  Socialization

o  Rindirect o  Roboject

Rindirect

Sophis#cated modularity for Android

•  Android does not support reusing components from another applica=on •  Package conflict •  Resources not found in R

•  Libraries do share the same package

•  Rindirect removes those limita=ons by genera=ng the missing/required R files •  Automated during your build process

•  Allow advanced modularity •  Improve component sharing


Roboject

A CDI for Android

•  Android code can be really =resome •  A lot of asynchronocity •  Service bindings, intents… •  Predominance of the main thread

•  UI code can be smaller •  Retrieving a View, Senng a Layout

•  Roboject dras=cally simplifies Android code •  @InjectX where X is Service, Intent, Extra, View, Layout… •  Addi=onal lifecycle method : onReady

•  Reduce the amount of code required to develop Android applica#ons

•  Minimum run#me overhead •  Extensible


@InjectLayout(R.layout.searchinputactivity)!public class TweetSearchActivity extends RobojectActivity {! @InjectView! private EditText editTextSearch;!! @InjectView! private Button buttonSearch;!! @Override! public void onCreate(Bundle savedInstanceState) {! super.onCreate(savedInstanceState);!! buttonSearch.setOnClickListener(new OnClickListener() {! public void onClick(View arg0) {! Intent intent = new Intent(TweetSearchActivity.this, !

! !TweetListActivity.class);! intent.putExtra("searchTerm”, ! !!

! ! !editTextSearch.getText().toString());! startActivity(intent);! }! });!

}!}!
