- PhoneStatusBar.java

private boolean inflateViews(NotificationData.Entry entry, ViewGroup parent) {
        StatusBarNotification sbn = entry.notification;
        RemoteViews remoteViews = sbn.notification.contentView;
        if (remoteViews == null) {
            return false;
        }
                     :
                     :
                     :
        applyLegacyRowBackground(sbn, content);

        entry.row = row;
        entry.content = content;
        entry.expanded = expanded;
        entry.largeIcon = largeIcon;

        return true;
    }

    void applyLegacyRowBackground(StatusBarNotification sbn, View content) {
        if (sbn.notification.contentView.getLayoutId() !=
                com.android.internal.R.layout.status_bar_latest_event_content) {
            int version = 0;
            try {
                ApplicationInfo info = mContext.getPackageManager().getApplicationInfo(sbn.pkg, 0);
                version = info.targetSdkVersion;
            } catch (NameNotFoundException ex) {
                Slog.e(TAG, "Failed looking up ApplicationInfo for " + sbn.pkg, ex);
            }
            if (version > 0 && version < Build.VERSION_CODES.GINGERBREAD) {
                content.setBackgroundResource(R.drawable.notification_row_legacy_bg);
            } else {
                content.setBackgroundResource(R.drawable.notification_row_bg);
            }
        }
    }

Check to process of setting Notificaion Background Color.

if (version > 0 && version < Build.VERSION_CODES.GINGERBREAD) {
                content.setBackgroundResource(R.drawable.notification_row_legacy_bg);
            } else {
                content.setBackgroundResource(R.drawable.notification_row_bg);
            }

If TargetSdkVersion is lower than Build.VERSION_CODES.GINGERBREAD(APILevel9), set R.drawable.notification_row_legacy_bg!!
