Preface to the Android30 question column

Objective
Last week when I saw a daily big brother, in the meal and chat, asked me if you are in the company is not the less than the staff, I am a little embarrassed to say yes, because the project team to do Android for the moment only I one. While this weekend, I think of myself, my current ability is a good use of tools, interfaces, grammar, etc. to complete the task of the company requirements, but the core of the technology, the principle of what, let me describe in detail, or smattering. The results are reflected in job interviews and on the salary you can get for your career. The interview process can not be extrapolate, can not describe the implementation process, pay pressure, raise the position is slow and so on.
In the process of self-criticism, think of giving yourself a constant self-excavation, learning the core of technology, the principle of opportunity, in the process of asking and answering to upgrade themselves. 30 ask is currently a tentative scope for Android technology, because I do not know can be encountered in the learning process problems, good framework, must master the knowledge to extract meaningful content. Now there are 3 pieces of content: life cycle, network access, picture loading. Although I do not know when to summarize the 30 questions, but there is such a goal, feeling in the use of relevant technology, occasionally ask yourself you understand.
The Ancients have clouds: 20 Afar, 30 stands, 40 is confused. So you know what I'm asking is the title 30 asked?
