fix: block coloros 15 fixSmallIcon method

[Nep-Timeline]

ColorOS 15.0.1 通过系统框架fixSmallIcon方法替换通知图标为应用彩色图标, 通过Hook系统框架拦截此方法阻止 ColorOS 15.0.1 替换通知图标

[fankes]

它竟然加到系统框架里了吗

[Nep-Timeline]

是的 他直接调用Notification.setSmallIcon覆盖图标了

[fankes]

你可否看看这个方法有没有别的可能性 hook SystemUI 绕过，因为 hook 系统框架的代价有点高

这不太行吧 他这个方法直接覆盖掉原本的SmallIcon

    private void fixSmallIcon(Notification notification, String pkg, String opPkg, boolean isExp) {
        Bundle notifExtras;
        if (notification == null || TextUtils.isEmpty(pkg)) {
            Slog.d(TAG, "fixSmallIcon: notification or pkg is null");
            return;
        }
        if (isExp || (notifExtras = notification.extras) == null) {
            return;
        }
        ApplicationInfo appInfo = (ApplicationInfo) notifExtras.getParcelable("android.appInfo", ApplicationInfo.class);
        if (appInfo == null) {
            Slog.d(TAG, "fixSmallIcon: appInfo is null");
            return;
        }
        if (NotificationInfoUtil.isAndroidPackage(pkg, appInfo) || NotificationInfoUtil.isSystemOrPlatformSignedApp(appInfo) || NotificationInfoUtil.isCommercialNotification(notification, opPkg) || isOplusAppUseSmallIcon(notification, pkg)) {
            return;
        }
        int appIconRes = appInfo.icon;
        if (appIconRes == 0) {
            Slog.d(TAG, "fixSmallIcon: Failed to get the app icon, no icon in appInfo");
            return;
        }
        Icon appIcon = Icon.createWithResource(pkg, appIconRes);
        if (appIcon == null) {
            return;
        }
        notifExtras.putBoolean(OPLUS_SMALLICON_USE_APP_ICON, true);
        notification.setSmallIcon(appIcon);
    }

这个方法在哪里调用的

这个方法在哪里调用的

Android Services中通知管理服务(NotificationManagerService)的enqueueNotificationInternal方法内

[Nep-Timeline]

https://cs.android.com/android/platform/superproject/main/+/main:frameworks/base/services/core/java/com/android/server/notification/NotificationManagerService.java;l=8058

        // Fix the notification as best we can.
        try {
            fixNotification(notification, pkg, tag, id, userId, notificationUid,
                    policy, stripUijFlag);
+           if (this.mNMSWrapper.getNMSExt() != null)
+               this.mNMSWrapper.getNMSExt().fixNotificationForOplus(notification, pkg, opPkg); // 此方法修改通知图标
        } catch (Exception e) {
            if (notification.isForegroundService()) {
                throw new SecurityException("Invalid FGS notification", e);
            }
            Slog.e(TAG, "Cannot fix notification", e);
            return false;
        }

ColorOS的行为比较的破坏原生逻辑 暂时不知道有什么别的办法

[fankes]

有够过分的，hook 系统框架有行为变更重启手机的需求，代价比较高，我看看后面有没有什么解决方案，明天等我上班后再研究
