No need to RemoveObserver(this) ?

[yoshiki, 2015/11/25 09:40:34]

Done.

+void ArcNotificationManager::OnNotificationPostedFromAndroid(
+    const arc::ArcNotificationData& data) {
+  ArcNotificationItem* item =
+      new ArcNotificationItem(this, g_browser_process->message_center(), data);
+  items_.insert(make_pair(data.key, item));

What will be in case if manager deleted with pending items? It seems potential
memory leak. Is any scoped ptr solution better? 

[yoshiki, 2015/11/25 09:40:34]

Done.

Log error in case not found?

[yoshiki, 2015/11/25 09:40:35]

This method may be called during OnNotificationRemovedFromAndroid(), and in such
case the item is always not found. Of cause we can detect such false removal.
But I don't think we need to add a logic only for debug messages here.

+    ArcNotificationItem* item = it->second;
+    items_.erase(it);
+
+    arc::ArcBridgeService::Get()->NotifyNotificationEvent(
+        key, arc::NOTIFICATION_EVENT_CLOSED);
+    delete item;
+  }
+}
+
+void ArcNotificationManager::NotifyNotificationClickedFromChrome(
+    const std::string& key) {
+  Items::iterator it = items_.find(key);
+  if (it != items_.end()) {
+    LOG(ERROR) << "CLIOCKE: " << key;

Debug print?

[yoshiki, 2015/11/25 09:40:34]

Done.

+    arc::ArcBridgeService::Get()->NotifyNotificationEvent(
+        key, arc::NOTIFICATION_EVENT_BODY_CLICKED);
