Development environment of apk file

Android is a development environment based on Java. It is a development language very similar to the widely accepted Java and much simpler than C++. This is a standardized mobile development environment. Google has also done an excellent job in writing API documents and providing samples.

Get SDK

Download and install the SDK [Software Development Kit] of android, which mainly includes core library files, a simulator, development tools and some demo sample files. Recommend Eclipse.

And androideclipse extensions. If you just use android, Eclipse

IDE is enough, but if it is the first time to develop a Java application, it is recommended to download the complete JavaSE Development Tool (JDK), because it contains the tools needed for application signing and publishing.

2. Application architecture

Android application architecture is very important. If you don't learn, the designed game will be a product that is difficult to fix bugs. You need to understand applications, activities, intentions and how they interact. Google provides a good information architecture here. What is really important is to understand why designing a game requires more than one activity process and how to design a game with good user experience. These should be integrated into the application life cycle.

3. Life cycle of the application

The life cycle of the application is managed by the AndroidOS operating system, and all active processes will be created as system commands. It is extremely important for applications to handle these events correctly, because end users don't know what is right. You'd better know this before you start designing the game, because it will save debugging time and avoid expensive redesign. For most applications, the default settings can start to work, but for games, you may need to adjust the signal of the singleton instance to on. Android will create a new active instance process by default, because it thinks it is more appropriate, while the game may only want to have an active instance process, which has little impact and needs to know some system state management.
