21. #gdgceesummit Complications “any feature in a timepiece beyond the simple display of hours and minutes” (Wikipedia)
22. #gdgceesummit Complication types -Short text -Long text -Range of values -Icon (small picture) -Image (big picture)
23. Complications coding
24. #gdgceesummit New in Preview 3 com.google.android.wearable.permission.RECEIVE_COMPLICATION_DATA Request permission to access Complication Data
25. #gdgceesummit Runtime permissions. Wearable version:) Now required for accessing Complication Providers from WatchFace apps
26. #gdgceesummit Each position need to be identified 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}; Complication ID
27. #gdgceesummit Each position must be mapped with array of supported types // Left and right dial supported types. public static final int[][] COMPLICATION_SUPPORTED_TYPES = { {ComplicationData.TYPE_SHORT_TEXT}, {ComplicationData.TYPE_SHORT_TEXT} }; Complication supported types
28. #gdgceesummit Data Providers and system trigger .onComplicationDataUpdate() sometimes /* Called when there is updated data for a complication id. */ @Override public void onComplicationDataUpdate( int complicationId, ComplicationData complicationData) { Log.d(TAG, "onComplicationDataUpdate() id: " + complicationId); mActiveComplicationDataSparseArray.put(complicationId, complicationData); invalidate(); } ComplicationData receiving
29. #gdgceesummit .onDraw() is the moment of drawing. ComplicationData where stored earlier @Override public void onDraw(Canvas canvas, Rect bounds) { ComplicationData complicationData; for (int i = 0; i < COMPLICATION_IDS.length; i++) { complicationData = mActiveComplicationDataSparseArray .get(COMPLICATION_IDS[i]); // ... Complications rendering
30. #gdgceesummit Complication may be deactivated or contain wrong data type if ((complicationData != null) && (complicationData.isActive(currentTimeMillis)) && (complicationData.getType() == ComplicationData.TYPE_SHORT_TEXT)) { ComplicationText mainText = complicationData.getShortText(); CharSequence complicationMessage = mainText.getText(getApplicationContext(), currentTimeMillis); Complications rendering
31. #gdgceesummit Actual drawing is trivial canvas.drawText( complicationMessage, 0, complicationMessage.length(), complicationsX, mComplicationsY, mComplicationPaint); Complications rendering
