Creating Your Own NDK Project

Now let’s look at an example of how to set up and use the NDK for your own Android applications using Eclipse. To create a new Android application that calls into native code, take the following steps:

1. Begin by creating a new Android project in Eclipse.

2. Navigate to your project directory and create a subdirectory called /jni. Inside this directory, place two C files: native_basics.c and native_opengl2.c.

3. In the /jni subdirectory, create a file called Android.mk. A sample Android.mk file might look like this, the one used in our sample application:

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_LDLIBS := -llog -lGLESv2
APP_ABI := all
LOCAL_MODULE    := simplendk
LOCAL_SRC_FILES := native_basics.c native_opengl2.c
include $(BUILD_SHARED_LIBRARY)
