Marketing begins the day you put your mobile app idea into production. But not everyone has a budget for marketing. Contrary to popular belief, most effective marketing strategies don't require any spending at all. How to put that strategy in place? From the period before you launch your app to after it goes on the
We all know how bothersome multi-platform mobile app formatting can get. Each platform is unique and exhibits different features, capabilities and behaviour. But then, multi-platform apps are truly “in” today, so you as the developer, need to find solutions to develop the best cross-formatted apps, without emptying up all your resources on developing for just
每次开机，第一时间会用边只 Apps ？ Facebook ？ Whatsapp ？定 check email 呢？一般而言，我们都会上App Store 或Google Play 去下载心仪Apps做自己想做的事‥‥‥。时间长了，会发现即使电话叉足电，闲置电池都会很快被耗尽。除此之外，也有不少电话被监听，中毒等新闻，网络上不少教学要机主格式化电话，备份资料。有见及此，想从programming 和用家角度去分享心得。 1. 熄机不一定是完全停止运作，永远不知道Apps 背后运行什么程式 在电脑世界中，背后运行的程式，叫做Thread。 Thread就是跟主程式分开，独立进行背景程式。只要背后写成一个回应方式(callback method) ，就可以定期更新主页。在Android / iOS 的世界中，有三种类型的Thread ：行单一个Task 、重覆行一个Task、什至连续一个Backend Class 去使用。 而以上所有Threads，如果不是用家设定教它停止运作，或用呼叫App Stack 扫走，电话很快就会耗尽电力。即使依正常步骤离开Apps，Threads 也未必停止运作。 如果有开发Android App 的经验，就会明白所有开机关机的程序都是先由截取按钮的事件触发的。即使离开某App ，如果开发者设计一个Thread，是一定需要用家到设定才叫它停止运作。 Hacker 可以从熄机的流程中截取按下和放开按钮的触发事件，可执行Thread去做任何事。如果你已经root 了电话或jail break iPhone， App 更可以窃取所有用户资料和联络人名单的电邮和电话号码。 2.要使用太多无谓的权限的Apps，安全性教人怀疑。 不少Apps 开发者，特别专注Android Developement 方面，都会多开几个权限，方便开发者改良。尤以拍摄App、开闪光灯的App其严重： 如果稍为细心留意，就知道开闪光灯跟开Wi-Fi、提取用户资料是风马牛不相及的事，然而，用家心急起来多数不为意App会提取你电话中什么权限而已。另外，Google与Apple就审批一个Apps 上架与否，处理方式大有不同。 Google 只会扫描APK一次，看看有没有明显的木马，和内容是否符合要求，最快可以两小时后就成功上架；Apple 却要数个星期。截图和文字描述被呈上后，全程由人手审批。如果要跟其他电子仪器沟通或配合，Apple App
Mobile. The very word makes some of us cringe these days. Everywhere you look in the marketing world, you see signs of it – mobile this, mobile that… Is it just me, or is it a bit overkill? Sometimes, I feel like we're pushing the idea of mobile to the limit. But then I look
There are just a few people on the internet by now that has never heard or played Five Nights at Freddy’s. Sure, it is originally a point and click game for PC’s and even consoles, but Five Nights at Freddy’s has gained a lot of attention from being playable in cellphones and tabs too. It
