56. #postiotour
Android Development Tools
Android Studio 3.0. Breaking Gradle API change. Kotlin. Code -> Convert Java file to Kotlin file.
xml new resource type tools:text="@tools:sample/lorem"
XML Fonts. In layout in the fontFamily option - browse available online fonts.
Profiler. CPU, Memory and Network state.
Instant Apps. Context menu -> Extract -> Modularize (in Canary 1)
Adaptive Icons. In the image asset wizard - option for adaptive icons.
Build Cache. Get output from the cache rather than re-run the task.
Java 8. Use {sourceCompativility JavaVersion.VERSION_1_8..}
Match attribute on build type on lib and app: "debug" lib with debug app.

Fragment Tricks
Fragments vs Views
Views display info and publish user interaction events (draw, clicks, scroll). Don't add external
dependencies to a View - service bind, network call.
Fragments integrate with lifecycle and may be aware of other app components. Bind to a service,
communicate with data model.
FragmentManager.beginTransaction()
.replace(R.id.container, fragment1)
.addToBackStack("state1")
.setReorderingAllowed(true)
.commit();
Optimisation

58. #postiotour
Fragment Tricks
Transitions
FragmentManager.beginTransation()
.setTransition(TRANSIT_FRAGMENT_FADE)
.replace..
Shared Elements
fragment
.setSharedElementEn
terTransition(.); // for
shared views
fragment
.setEnterTransition(.)
; // for not shared
views
.addSharedElement(vi
ew, "target") // name of
the element ..

Contextual App Experiences
Nearby Messages exposes simple publish and subscribe methods.
Nearby Notifications Triggers an app intent from
beacon to launch an app
Awareness API:
Fence API (Callbacks), Snapshot API (Polling)
Require Google Play services 7.8.0 or higher.
Eddystone supported beacon hardware required. Rely on the phone
detecting a Bt Low Energy beacon nearby.
Fused Location Provider, Activity recognition, Geofencing,
Place detection, State of the device (Time, Headphones)

Android Fireside Chat
Q: How do you ensure that OEM actions does not break OS
A: Project Treble created a foundation layer for Android, vendor interface. Reduce the cost of updating
Android OS. New devices will have it.
Q: What's the difference between Systrace and Profiler
A: Systrace gets all of its data from the Linux kernel. Profiler sample the run-time of your app and its
functions.
Q: Are you still working on a data binding
A: Yes it one of our responsibilities
Q: How Kotlin related to Swift
A: We are independent. Kotlin was announced in 2011.
Q: Will Google Play Services will be open-source as Firebase SDK
A: Play Services extends some google apps, which are not open-sourced.
Q: Are you going to implement platform framework components using Kotlin
A: Java code for the near future because of millions of code lines. Main goal -make the Java and Kotlin API
interoperatable
