小米开发平台应用删除前台服务通知导致的闪退问题说明

• 近期发现较多应用出现闪退现象，具体trace如下：

• 原因是受Google的一笔安全校验Patch影响：https://cs.android.com/android/platform/superproject/+/master:frameworks/base/services/core/java/com/android/server/notification/NotificationManagerService.java;l=3413

private void enforceDeletingChannelHasNoFgService(String pkg, int userId,
                String channelId) {
            if (mAmi.hasForegroundServiceNotification(pkg, userId, channelId)) {
                Slog.w(TAG, "Package u" + userId + "/" + pkg
                        + " may not delete notification channel '"
                        + channelId + "' with fg service");
                throw new SecurityException("Not allowed to delete channel " + channelId
                        + " with a foreground service");
            }
        }

也就是Google限制了存在前台服务时，不允许应用删除与前台服务绑定的channel。

以上，请开发者检查处理，感谢支持！
