We’ll start with a basic layout (architecture) of the components of the app including the Java main activity, a native interface (also written in Java), and the C implementation. Next we’ll see how to compile the native code, and finally we’ll test on the emulator. Let’s get started. CHAPTER 2: Gaming Tricks for Phones or Tablets Application Architecture Let’s consider what we wish to accomplish with this application: We want to create the basic Android application. ”. Within the project, we will create a native folder with files to accomplish the following: Create a native library with a main subroutine that will be called from the Android main activity using JNI.
You will get frustrated very quickly with the touch screen. Some games simply require a controller. This is the reason for the next section: Bluetooth controllers. I am sure your customers will be happy that you provide Bluetooth controller support in your game.

With the rising in popularity of other smartphones, its creators released an SDK for other platforms such as Android and iPhone. The Zeemote consists of a joystick and four buttons (A, B, C, and D - see Figure 2–10).
CHAPTER 2: Gaming Tricks for Phones or Tablets Figure 2–5. so ... so ... These are JNI messages that tell us the library loaded successfully and the native methods can now be invoked within Java. OnMessage() method. Success! We have got our feet wet with this section but there is so much more we can do with native apps. We have learned the basics of Java/C interaction which serve as the foundation to the next section, where we build upon previous knowledge to learn more advanced techniques such as how to cascade audio, video, and other types of events into the native side.
