A lot of things happened from 2014 to 2016, and now it's a foregone conclusion to forget about the troubles, to find something to do before, to fill the brain and not to think about it.before, always want to do a hanging machine game, a variety of platforms and development language have been selected, from HTML5 to c,c++,c#,unity3d a variety of small demo write a lot, and finally chose the Android platform to do ....Online read a lot of instances, abo

It is relatively simple to generate a verification code and it is not difficult to draw a picture. However, everyone does not like to read the manual or do it by themselves. It is generally because I copied a piece of code online, in fact, drawing is quite interesting. However, the verification code generated by a common Font does not have any "combat power". It is easy to identify the content of the verification code by the program, and then it is ea

In the interface design of the Android UI Development topic (i), we introduce the Android platform Resource usage and bitmap related classes, and then give you an example of how various classes are useful and attentive. Today we continue to understand the more important drawing classes in the Android.graphics package. First, Android.graphics.Matrix Some common

Typical drawing process for 1.1.1 applications We know that Bufferqueue has up to 32 bufferslot, so what is the purpose of this design? One possible reason is to improve graphics rendering speed. Because if there are only two buffers, imagine that when the output efficiency of the application producer is greater than the processing speed of the consumer, it will soon dequeue the buffer and be in the waiting state, causing unnecessary trouble. Of cour

Do not care about the size of the remaining memory, in fact, many people are the habit of using other systems brought here. Android most applications do not exit the design actually makes sense, which is related to the scheduling mechanism of the process. If you knew Java, you would have a clearer idea of the mechanism. In fact, like the Java garbage collection mechanism, the system has a rule to reclaim memory. There is a threshold for memory schedul
