Relation Mapping) framework that simply uses methods such as Save () and delete () to do additions and deletions. Activeandroid–android Lightweight ORM Framework RetrofitRetrofit is similar to the ORM concept in the Java World, where ORM transforms structured data into Java objects, and retrofit transforms the data returned by the rest API into Java objects for ease of operation. It also encapsulates the invocation of network code. Retrofit–java (Android) Rest Interface E

it is in the path drawing.Strokes vs. fragmentsEach clicked Point has a block, some of which are hollow (such as 1, 2, 3) and have a solid (such as 4). These points are called anchor points. The segment between each of the two anchor points is called a fragment.The process of drawing a path is actually the process of specifying the location of the anchor point, and the position of the anchor determines the

My path to operating system development and learning. Below I will list the time used in each stage 1) Assembly, I used the longest time at this stage. I have never played low-level before learning Assembly. I am not used to having to do not like for-loop, and I am not used to allocating memory myself, I spent almost 3-4 years

It mainly introduces how to use custom call handler to implement user operation logging.

Next we will introduce the most widely used IOC container-unity in the Enterprise Libra

Without the mouse is very difficult to get, we do not feel the same, but after I contacted the study of Vim, my view was completely changed. I will start with my learning
