プロトタイプ作成でよく使うのでまとめておく。
xml:@android:drawable/ic_menu_***
Javaコード:android.R.drawable.ic_menu_***
で使える41種類。
(SDK内にはこの他にもメニューアイコンリソースがあります)
アイコン画像はSDKのdrawable-hdpi配下のもの。
2.xは72x72px、4.xは48x48pxとなっている。

2.3 から GC の方式が変わったので、SoftReference や WeakReference で Bitmap をキャッシュするのはあんまり意味ないからオススメしないそうだ

これどこ情報なんだろう?ListViewに表示するTwitterアイコンのキャッシュにSoftReference使ってるけど、確かに2.2、2.3、4.xで動き違って困ってた。2.3と4.xはすぐキャッシュが解放されてて再取得が走る... > RT

@yanzm 知りませんでした(・o・) そのうち自作アプリもLruCache使うようにしてみます。developer.android.com/training/displ…
