LgameLgame is a Chinese-developed Java game engine, with Android and PC (J2SE) two development versions. Its bottom-level plotter Lgrpaphics package has J2SE and all the graphics APIs provided by J2ME (PC version in Graphics2D package, Android version with canvas simulation), so you can apply J2SE or J2ME development experience directly , the main code between the two versions can be ported to each other. The Android version has a built-in AdMob interface that eliminates the need to configure XML direct hard-coded admob ad information. In addition to basic sound, graphics, physics, sprites and other commonly used components, but also built-in IOC, XML, HTTP and other common Java components of the package, the cost is a large jar volume, the PC version has broken through the 1.2mb,android version has been simplified also around 500KB. In addition, the engine has a built-in J2ME elf class and related components implemented in accordance with 1:1, which translates most j2me games into Android or PC versions.
Project Address:http://code.google.com/p/loon-simple/ openintentsWith "Intents", Android provides an excellent foundation for connecting software and dynamic replacement components. Google defines a number of intents (such as: Call, select a contact on the contact list, open the browser, battery replacement to provide tips, etc., detailed list see: Available intents and intent Class) However, any program can freely define additional intents and content-providers. We can easily associate the process of independent development (such as in this game) with very few possibilities to work well with the newly defined intents and interfaces. Our goal in this project is to collect ideas that are likely to be useful across multiple projects (and most likely already implemented by other independent programmers), define a batch of intents and interfaces that are reasonable and scalable, provide a basic but stable and efficient implementation that can be applied by other Android programs, Especially the other participants in the competition. Openintents himself will take part in the competition. We provide small sample programs to demonstrate the use and characteristics of openintents. Because we focus on those intents,google that are often used, it is also possible to provide their own standard intents in the near future (for example, on calendars ...). When that happens, we provide a transparent interface to call Google's implementation directly, and your existing programs can use Google's new features without changing anything. And, because your program in the early design is already support intents, when Google's intents out, you can easily direct their intents. It is also possible that Google may borrow some intents developed by Openintents. In any case, if your program uses openintents, you will gain additional added value as well as other use of openintents programs to support each other, thereby enhancing the overall user experience.
