4. Best Practices
“Android Programming for Java Developers”
“Mobile Development for Server and Desktop Developers”
Chet Haase - Lead Android UI team
- Talk a lot about extra allocations
- Talk about memory impacts
- Tragedy of the commons “every device is a village”
8 Parts so far

5. Android M

6. Android Mars ?
*Disclaimer - I have no idea really
And yes I know there are no peanuts in a mars bar

7. Android M
Out now!*

8. User Controls
Google I/O 2015 - Android M Permissions https://www.youtube.com/watch?v=f17qe9vZ8RM

9. User Controls
Apps targeting M can:
can ask for any permission at any time
Legacy apps will:
get all permissions at install time as before
Users can:
deny any permission on request
deny any permission at any later time - even legacy apps

10. Voice Interactions
VoiceInteractor - confirm & prompt for response
Before - “Play music on TuneIn” , your app could be launched
Now - It will reply “What Genre?”

11. Fingerprint API’s
- FingerprintManager.authenticate()
- Verify that authorized user is present (ex: purchases)
- Your app controls all UI
- KeyguardManager.createConfirmDeviceCredentialsIntent()
- Present lock screen to user
- startActivityForResult with RESULT_OK
- github.com/googlesamples/android-ConfirmCredentials

12. Android Backup
- All data backed up by default when targetSDK M
- Optional scheme file for includes & excludes

13. GCM Network Manager
- Like JobScheduler but not api level specific
- L+
- Included in Google Play Services 7.5+
- Limit networks tasks to whilst charging, wifi ..

14. Power Improvements
- Doze
- Untouched devices become ‘inactive’
- Wait longer to wake up for background tasks
- Resume normal operation when moved, used, or plugged in
- Standby can improve by 2x
- App Standby
- Unused apps lose network access
- Resume when launched, used or plugged in

15. Assistant Support
Google Now “on tap”
API’s to provide the assistant with more data
Assistant doesn’t run until long press on home button
- See SDK docs:
- http://developer.android.com/reference/android/app/Application.OnProvideAssistDataListener.html
- http://developer.android.com/reference/android/app/Activity.html#onProvideAssistData(android.os.Bundle)

16. Data Binding
Connect data & UI elements
Automates listener creation, msg sending, setters
Pre-processed at build time (generated code)
Better performance & “guaranteed best practice”
MVVM - ViewModel

17. Data Binding
dependencies {
classpath "com.android.tools.build:gradle:1.3.0-beta1"
classpath "com.android.databinding:dataBinder:1.0-rc0"
}
<variable name="user" type="com.example.Fruit"/>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@{fruit.price}"/>
