Open GPS trackerGpstracker is a project that can use Android maps to record your driving or travel routes. Before you leave, open the software selection and start recording, and the routes you pass will be displayed on the map in real time, the current driving speed is also displayed. The program will automatically save the route for future viewing Based on the title set by the user. You can also share the route with your friends. The gpstracker Project is a complete map application, which consists of two main components. The first part is a system service for collecting and storing GPS tracking data, the second part is that map activity controls the tracking data and displays the provided interface on the map. The gpstracker project uses some features of the osmdroid project. OpenStreetMap is a world map that can be freely edited. It allows you to view, edit, or use geographic data from all over the world to help you.

LgameLgame is a Java game engine developed by Chinese people. It has two development versions: Android and PC (j2se. The lgrpaphics at the bottom layer encapsulate all graphics APIs provided by j2se and j2s (PC uses graphics2d encapsulation, and Android uses canvas simulation ), therefore, we can apply j2se or j2's development experience directly, and the main code of the two versions can be transplanted to each other. Android has a built-in AdMob interface. You do not need to configure XML to directly hardcode AdMob ad information. In addition to basic sound effects, graphics, physics, Genie, and other common components, the engine also has built-in encapsulation of commonly used Java components such as IOC, XML, and HTTP, at the cost of a large jar volume, the PC version has exceeded 1.2 MB, and the Android version is simplified to around kb. In addition, the engine also has built-in 1-to-1 Implementation of the j2_genie class and related components, you can translate the vast majority of j2_game to Android or PC.

OpenintentsWith "Intents", Android provides an excellent foundation for connection software and dynamic replacement components. Google defines a batch of intents (for example, call, select a contact on the contact list, open the browser, and provide a prompt when the battery is changed. For details, refer: available intents and intent class) but any program can freely define additional intents and content-providers. We can easily think of independently developed programs (such as in this competition), and very few may work together with newly defined intents and interfaces. The goal of this project is to collect ideas that may be useful in multiple projects (and may have been implemented by other independent programmers ), define a batch of intents and interfaces with reasonable and good scalability, provide basic but stable and effective implementation, and can be applied by other android programs, especially other programmers participating in the competition. Openintents will also participate in this competition. We provide a small sample program to demonstrate the usage and features of openintents. Because we focus on the commonly used intents, Google may also provide their own standard intents (such as about calendar...) in the near future ...) At that time, we will provide transparent interfaces to directly call Google's implementation method, and your existing programs can directly use Google's new features without changing anything. In addition, because your program supports intents at the initial stage of design, when Google intents comes out, you can easily directly use their intents. It is also possible that Google may borrow some intents developed by openintents. In any case, if your program uses openintents to provide mutual support with other openintents programs, you will get additional value to enhance the user experience.
