It seems that only the GetImageForNetwork function should be called and not the
constructor?
Could the constructor be private?

Moved NetworkIcon into the .cc file, put GetImageForNetwork into a namespace.

+ public:
+  enum ResourceColorTheme {
+    COLOR_DARK,
+    COLOR_LIGHT,
+  };
+
+  class AnimationObserver {
+   public:
+    virtual ~AnimationObserver() {}
+    // Called when the image has changed due to animation. The callback should
+    // trigger a call to GetImageForNetwork() to retrieve the image.
+    virtual void NetworkIconChanged() = 0;
+  };
+
+  NetworkIcon(const std::string& service_path, ResourceColorTheme color);
+
+  // Get the image for the network associated with |service_path|.
+  // |color| determines the color theme. If the icon is animating (i.e the
+  // network is connecting) and |observer| is provided, it will be notified
+  // when the icon changes.
+  static gfx::ImageSkia GetImageForNetwork(
+      const chromeos::NetworkState* network,
+      ResourceColorTheme color,
+      AnimationObserver* observer);
+
+ private:
+  // Determines whether or not the associated network might be dirty and if so
+  // updates and generates the icon. Does nothing if network no longer exists.
+  void Update(const chromeos::NetworkState* network);
+  // Updates strength_index_ for wireless networks. Returns true if changed.

put strength_index_ between || for consistency

newlines between commented methods/members?

[stevenjb, 2012/11/27 00:58:18]

Done.

+  bool UpdateWirelessStrengthIndex(const chromeos::NetworkState* network);
+  // Updates the local state for cellular networks. Returns true if changed.
+  bool UpdateCellularState(const chromeos::NetworkState* network);
