Using the Sample Applications

The NDK includes two sample applications that illustrate how to use native code in your Android applications:

hello-jni — A simple application that loads a string from a native method implemented in a shared library and then displays it in the application UI.
two-libs — A simple application that loads a shared library dynamically and calls a native method provided by the library. In this case, the method is implemented in a static library imported by the shared library.
For each sample, the NDK includes an Android application project, as well as the corresponding C source code and the necessary Android.mk and Application.mk files. The application projects are provided in /apps//project/ and the C source for each application is provided in /sources/samples//.

Once you have installed the NDK, you can build the shared libraries from the NDK by using these commands from the root of the NDK directory:

$ make APP=hello-jni — compiles /sources/samples/hello-jni/hello-jni.c and outputs a shared library to /apps/hello-jni/project/libs/armeabi/libhello-jni.so.
$ make APP=two-libs — compiles /sources/samples/two-libs/second.c and first.c and outputs a shared library to /apps/two-libs/project/libs/armeabi/libtwolib-second.so.
Next, build the sample Android applications that use the shared libraries:

If you are developing in Eclipse with ADT, use the New Project Wizard to create a new Android project for each sample, using the "Import from Existing Source" option and importing the source from /apps//project/. Then, set up an AVD, if necessary, and build/run the application in the emulator. For more information about creating a new Android project in Eclipse, see Developing in Eclipse.
If you are developing with Ant, use the android tool to create the build file for each of the sample projects at /apps//project/. Then set up an AVD, if necessary, build your project in the usual way, and run it in the emulator. For more information, see Developing in Other IDEs.
