デバッグでよく使うコマンド dumpsys編 その4 SurfaceFlinger

前回はdumpsysのActivity系情報を紹介しましたが今回はSurface情報を紹介します。

Surfaceの情報を取得するには、SurfaceをまとめるSurfaceFlingerというサービスのdumpを取得する必要があります。
いつも通りのdumpsysコマンドですが、SurfaceFlingerの情報のみを取得する場合は下記のようなコマンドになります。

$ adb shell dumpsys SurfaceFlinger

取得できる情報は下記”SurfaceFlingerのdump”となります。

よく使う情報としては”Visible layers”以下にならぶLayerの情報です。
このLayer一つがSurface一枚を表しています。
よく見る値としては下記になります。

・z:Surfaceのz orderを表す。
   Surfaceの重なり方を確認する際に使用する。
・visibleRegion:Surfaceが表示される領域を表す。
         [左、上、右、下]の座標を確認する際に使用する。
・alpha:Surfaceの透明度を表す。
     0に近い値であるほど透明になる。

このほかにもDisplayの情報やWindowのdumpとの連携等紹介したいことは他にもあるのですが、今回はここまでとします。
次回も引き続きSurfaceFlingerの情報を紹介します。

ちなみに以下のSurfaceFlingerのdumpはエミュレータ起動後キーガード表示時に取得したdumpとなっています。
