Google が ”Glass at Work” で Google Glass のエンタープライズ向け利用を推進

Google が ”Glass at Work” で Google Glass のエンタープライズ向け利用を推進してゆくことを宣言しました。
詳しくは Google Glass Info さまにて紹介されているため割愛しますが、ここで重要なのは

・既に Glass を用いたビジネス展開が進みつつある
・Google は Glass を用いたビジネスを支援してゆくことを表明している

という点です。

Google は Glass に消極的だ　等の噂もささやかれる昨今ですが、一般企業との協業を進めてゆくことが宣言されたことは非常に重要な意味を持ちます。
既にアナウンスされていたメガネ関連メーカー以外とも Google がビジネスを進めてゆくという事実は、Glass にとって非常に明るいニュースだと言えるでしょう。


ただし、現時点の Glass は Explorer Program としてアメリカで展開されているだけであり、この "Glass at Work" でも日本企業(かつ アメリカに拠点がない企業) は対象外です。

Glass のビジネス動向については、今後も継続して注視してゆきたいと思います。

上記のような例外が発生することがあります。
これは、XE12 で当該メソッドがなくなったことを表していますので、SDK をアップデートし、実装を修正しましょう。

原因不明だが、カメラをクローズせずにアプリを起動したからかもしれない。
再起動して、正しいコードのアプリを動かせば問題ないと思われる。

いちど LiveCard#publish() をコールした LiveCard インスタンスに対し、もう一度 publish() をコールしてはいけない模様。

リファレンスには確かに

Note that once a card using RemoteViews is published, changes made to the views by calling set* methods will not be visible in the timeline unless you explicitly call setViews on the live card again to force an update. 

と書いてある。
 LiveCard を更新する場合は、LiveCard にセットした RemoteViews の set系のメソッドを使えと。

流れとしては、

                    RemoteViews rv = new RemoteViews(packageName,
                            R.layout.testlayout);
                    rv.setTextViewText(R.id.textViewResultCombo, "p= " + mPitch);
                    mLiveCard.setViews(rv);

という感じに、
RemoteViews を new して
　↓
RemoteViews#set* でビューを更新して
　↓
LiveCard#setViews() で RemoteViews をセット
という感じみたい。

一度 LiveCard#setNonSilent() をコールしたあと、もう一度コールしてはいけないということかな？
二度目以降の setNonSilent() をやめたら、この例外は発生しなくなりました。

※とりあえずのメモ書きであり、対策に関して全面的に信用はしないで下さいね。
