function initialize()内でWatchFaceDelegete.initialize()としてまず初期化し、function onPowerBudgetExceed(powerinfo)として関数を書いて、その中にコメントを記述します。powerinfo.executionTimeAverageは実際に１回のパーシャルアップデートの処理にかかった１分間の平均。powerinfo.executionTimeLimitがパーシャルアップデートの１回当たりの処理に許されている時間です。
ただ、これだけは動いてくれなくて、今まで何のためにあるのだろうと思っていたもう一つのファイルXXXXapp.mcを修正する必要があります。修正するのはこの中のgetInitialViewの部分です。デフォルトでは次のようになっているはずです。
function getInitialView() as Array<Views or InputDelegates>? {
return [ new XXXXView() ] as Array<Views or InputDelegates>;
}
これをサンプルプログラムに倣って次のように書き換えます。
function getInitialView() {
if( Toybox.WatchUi.WatchFace has :onPartialUpdate ) {
//Sys.println("del");
return [ new XXXXView(), new XXXXDelegate() ];
} else {
return [ new XXXXView() ];
}
