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

Voice InteractionsVoiceInteractor - confirm & prompt for response

Before - “Play music on TuneIn” , your app could be launched

Now - It will reply “What Genre?”

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

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

Assistant SupportGoogle 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

Data BindingConnect data & UI elements

Automates listener creation, msg sending, setters

Pre-processed at build time (generated code)

Better performance & “guaranteed best practice”

MVVM - ViewModel

Google I/O 2015 - What's new in Android https://youtu.be/ndBdf1_oOGA?t=785

Data Bindingdependencies {

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}"/>
