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

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()

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}"/>
