I don't know when I was involved in Mobile development area，but now, I can say that I am a full time employee about developing Mobile services, although those of services serve PC at the same time, but almost all of ours customers just only use Mobile services that is provided by us. I used to develop traditional software but I am soon translate to a Mobile software engineer, and I had never thought that I will be a this role. But this thing have happened and I am not any unwilling to engage on such thing. On the contrary I like what I am doing. What's up? Let's look around nearby us,in bus, metro and even in store and street,what are those people doing? Everybody's head droop, peer the Mobile phone, they sometimes smile and headache-likes occasional. Everyone are appealed by their Mobiles, but the App or Service of Intelligent Mobile is relative so rare . You may disagree with me, there are more than thousand and million App already in App Store of Apple company, and also so many another App is exist in another kinds of platform. But... But... But do you know how long that the intelligent Mobile is thrived on? When does the 4G network build? When does the first time to meet your favorite App? It's easy to answer those questions except Alzheimer's people. Yes , just only a few years ago those things are appearance, we are surprised what happened now, but we are already for acclimatization. We are not uncomfortable for that can't view the balance of bank immediately, We are not satisfied that need to pay with paper money, the online pay is amaze thing, you don't need face embarrassment that you haven't any pocket money while seller also haven't so you can't buy that things. Those online service is a part of ours life. The load those services of equipments are intelligent Mobiles. What a short time the intelligent Mobile is developed! So many things is a half way for us or is just a begin in Mobile industry. So the social need to assemble too many forces to fix the era's development course. Me too, I even don't know what happened but actually I was included now. Customer think that the App need more stable, and also customer have so many pain points that need to solving. So I will have some proofs that large parts come come my work experience share to you. 1, As the economic developing a large group of people will own a Mobile. I needn't to give your statistics, because many articles and groups have been gave. India is large population country, but a computer or even a Mobile is a expensive thing for an Indian, so many families just only have a Mobile phone, they cherish hope that they can have a Mobile phone even is a cheapest one, and India's economy is large march on. If they make their dream come true, there are more Mobiles will join into Internet. They have so many personalize beliefs and habits, so they need so many Apps to work for them and those Apps need to be developed in future. So this market is very large indeed. 2, Security problem. Operation about finance business is a large part of things in our Mobile surfing the Internet. Financial data is sensitive and very important. The security problem is more and more emergency. We either careless this thing or have throw enough money or energy into it in the past. There will be a large group of companies be found to do this things specially, so there is big opportunity for a developer or a people that want to be a developer. 3, App special lib is a main technology for development environment likes Android and IOS and will be the main kinds of skills for Mobile development. but there are another three more import development methods can not be ignored. Html5 client that can be compatible with Android and IOS and also PC platform. I am a traditional Java developer, but I can give the Mobile services not so many learn curve, that the key skill is Html5, I can support REST standard services for Html5, that Html5 is suitable for Android and IOS also PC, That is the very thing can write once and can run multiple platforms. Just only Html5 is not enough for some complex functions. So hybrid method is a good solution, Android and IOS APP also have some Html5 pages, this method saving much time that we can do it in the other things. Finally we have an very simple and effective way to develop an Application. That just need you to config some files, and you can drag some virtual components to consist your Applications. So some non-techlology person can development their own Applications. Mini-program of WeChat is example of this kind. 4, Personalize development is great improve user's experience. There are many things need to do in future. In a Retail System, one can retrieve a personalize information from the same system, If user does't login the system they will get the same information. 5G network is developing. Our's spend in Mobile network is still too expensive and too slow for us to experience some kind of function.e.g. Broadcast, Video, and so on. So many companies begin to deployment Mobile business.There must be so many opportunities for developer if you know those trends.
