Zookeeper Install cocos2d-v2 The current cocos2d-v3 is not very stable, and many functions are still being modified. For the sake of stability, we still use v2 wget -c http://cocos2d-iphone.googlecode.com/files/cocos2d-iphone-2.1.tar.gz /

Core Principles: Object serialization Procedure 1. serialize the object to be saved 2. Save the serialized object as a String (this article saves it as a byte array in the String type converted to hexadecimal format) 3. deserialize the stored String

This month, I received a project to write an APP for software management like a 360 assistant. I encountered a problem: multi-thread breakpoint download. This is because you have not previously written this application function. Therefore, you have

In fact, not only android mobile phone development, but all software development should pay attention to code efficiency issues! In general, the memory should be used as little as possible to implement the same function, and the minimum command is

The previous articles mainly focused on the description of the input cache area when analyzing the data stream of OMX_Codec. Here we separately aim to deepen our understanding of SurfaceFlinger, the application for the output cache area used for

Why use dp/dip? What is the appropriate dp value for the width/height of the navigation bar? In general, how many heights should each control display? This article aims to solve these problems. 1. During Android development, we cannot ignore the
