Mobile Develop

From the beginning of my junior year to start work, almost all are lonely development because around the development of iOS not much, in addition to learning the code of open source excellent style skills the rest is their own, so developed a lot of

Our mobile app testing, mainly for Android and iOS two major operating systems, the overall Android phone model, version, and many bugs, iOS relatively few bugs. Here are some of the most easily overlooked test points for Android.1. App Overlay

Nstimer is often used in iOS development, especially in small games, but for beginners, the memory release problem is often not noticed, and its basic usage is summarized as follows: First, initialization method: There are five kinds of

Principle: The principle is not much said, look under the Android source code will know. First get Assetmanager, then use Assetmanager Openxmlresourceparser method to get Xmlresourceparser, Start parsing the Androidmanifest.xml file in apk with

Objection is a lightweight, dependency injection framework"Dependency Injection" is a design pattern for object-oriented programming to reduce the coupling between code. is usually implemented based on an interface, which means that no new object

For mobile clients, the importance of the network is self-evident. Common network requests have synchronous get, synchronous post, asynchronous get, asynchronous post. Today, let's look at four ways to implement network requests.One, synchronous get/
