So… What’s coming in Android Wear 2.0?

Problem No.1: Tethering

Freedom from tetheringmeans “freedom without phone”

Officially supported by:● LGE Watch Urbane

2nd Edition● Huawei Watch

Android Wear 2.0 Preview is available for

Upcoming: access Market directly from watch

What makes custom Watch Faces different but at the same time similar?

Complications- “any feature in a timepiece beyond the simple display of hours and

minutes” (Wikipedia)

● Short text● Long text● Range of values● Icon (small picture)● Image (big picture)

Complication types:

Complications coding

Each complication should have unique id

private static final int LEFT_DIAL_COMPLICATION = 0;

private static final int RIGHT_DIAL_COMPLICATION = 1;

public static final int[] COMPLICATION_IDS = {LEFT_DIAL_COMPLICATION, RIGHT_DIAL_COMPLICATION};

// Left and right dial supported types.

public static final int[][] COMPLICATION_SUPPORTED_TYPES = {

{ComplicationData.TYPE_SHORT_TEXT},

{ComplicationData.TYPE_SHORT_TEXT}

};

ComplicationData type stores complication info (text, icon, type)

onComplicationDataUpdate() is initiated by Data Provider

private SparseArray<ComplicationData> mActiveComplicationDataSparseArray;

…

@Override

public void onComplicationDataUpdate(

int complicationId, ComplicationData complicationData) {

Log.d(TAG, "onComplicationDataUpdate() id: " + complicationId);

// Adds/updates active complication data in the array.

mActiveComplicationDataSparseArray.put(complicationId, complicationData);

invalidate();

}

Rendering complications

private void drawComplications(Canvas canvas, long currentTimeMillis) { // onDraw()

for (int i = 0; i < COMPLICATION_IDS.length; i++) {

ComplicationData complicationData = mActiveComplicationDataSparseArray.get(COMPLICATION_IDS[i]);

if ((complicationData != null) && (complicationData.isActive(currentTimeMillis))

&& (complicationData.getType() == ComplicationData.TYPE_SHORT_TEXT)) {

ComplicationText mainText = complicationData.getShortText();

canvas.drawText( mainText, 0, mainText.length(),

complicationsX, mComplicationsY, mComplicationPaint);

Data Providerswill stand behind the scenes as sources of data for

complications

One complication may use different providers as the data source

DataProviders coding

Extend ComplicationProviderServiceand declare it in AndroidManifest.xml

android.support.wearable.complications.ACTION_COMPLICATION_UPDATE_REQUEST

android:icon

android.support.wearable.complications.UPDATE_PERIOD_SECONDS

android.support.wearable.complications.PROVIDER_CONFIG_ACTION

<meta-data

android:name="android.support.wearable.complications.SUPPORTED_TYPES"

android:value="SHORT_TEXT"/>

ComplicationProviderServiceinternals

onComplicationActivated()

onComplicationUpdate()

onComplicationDeactivated()

Exposing data from providerin onComplicationUpdate()

@Override

public void onComplicationUpdate(int complicationId, int dataType, ComplicationManager complicationManager) {

int randomNumber = (int) Math.floor(Math.random() * 10);

String randomNumberText = String.format(Locale.getDefault(), "%d!", randomNumber);

switch (dataType) {

case ComplicationData.TYPE_SHORT_TEXT:

ComplicationData complicationData = new ComplicationData.Builder(ComplicationData.TYPE_SHORT_TEXT)

.setShortText(ComplicationText.plainText(randomNumberText))

.build();

break;

...

Exposing data from providerTrigger update with ComplicationManager.updateComplicationData()

@Override

public void onComplicationUpdate(int complicationId, int dataType, ComplicationManager complicationManager) {

...

if (complicationData != null) {

complicationManager.updateComplicationData(complicationId, complicationData);

}

What whas really distracting in AndroidWear 1.X notifications?

White light when you receive notification

Visual updates to notifications in 2.0Dark theme, Material Design for Android Wear

Large dark notificationEasier to read, but less-distracting in everyday life

Notifications and messages

Notification MessagingStyle

Allow smart replies, based on Google Assistant

NotificationCompat.Action action =

new NotificationCompat.Action.Builder(R.drawable.ic_reply_icon,

getString(R.string.label), replyPendingIntent)

.addRemoteInput(remoteInput)

// 1) allow generated replies

.setAllowGeneratedReplies(true)

.build();

Use MessagingStyle for notification

Notification noti = new NotificationCompat.Builder()

.setContentTitle(messages.length + " new messages with " + sender.toString())

.setContentText(subject)

.setSmallIcon(R.drawable.new_message)

.setLargeIcon(aBitmap)

// 2) set the style to MessagingStyle

.setStyle(new NotificationCompat.MessagingStyle(resources.getString(R.string.reply_name))

.addMessage(messages[0].getText(), messages[0].getTime(), messages[0].getSender())

.addMessage(messages[1].getText(), messages[1].getTime(), messages[1].getSender()))

Response to notifications in AndroidWear 1.X“Voice input”

More input methodsHandwriting, suggestions, keyboard

1.38-inch full circle P-OLED480 x 480348ppi

How full-size keyboard works on the small screen?

“Magic button” - center of navigation concepts

The most complicated UI pattern of AndroidWear 1.X?- “2D Picker”

The answer to this problem in AndroidWear 2- Recommended pattern is “1D Layouts”
