The native-activity sample provided with the Android NDK demonstrates how to use the android_native_app_glue static library. This static library makes creating a native activity easier by providing you with an implementation that handles your callbacks in another thread, so you do not have to worry about them blocking your main UI thread. The main parts of the sample are described below:
The familiar basic structure of an Android application (an AndroidManifest.xml file, a src/ and res directories). The AndroidManifest.xml declares that the application is native and specifies the .so file of the native activity. See NativeActivity for the source or see the <ndk_root>/platforms/samples/native-activity/AndroidManifest.xml file.
A jni/ directory contains the native activity, main.c, which uses the android_native_app_glue.h interface to implement the activity. The Android.mk that describes the native module to the build system also exists here.
To build this sample application:
Create a new project in Eclipse from the existing sample source or use the android tool to update the project so it generates a build.xml file that you can use to build the sample.
In Eclipse:
Click File > New Android Project...
Select the Create project from existing source radio button.
Select any API level above Android 2.3.
In the Location field, click Browse... and select the <ndk-root>/samples/native-activity directory.
Click Finish.
On the command line:
Change to the <ndk-root>/samples/native-activity directory.
Run the following command to generate a build.xml file:
android update project -p . -s
Compile the native code using the ndk-build command.
cd <ndk-root>/platforms/samples/android-9/samples/native-activity
<ndk_root>/ndk-build
Build and install the application as you would a normal Android application. If you are using Eclipse, run the application to build and install it on a device. If you are using Ant, run the following commands in the project directory, then run the application on the device:
ant debug
adb install bin/NativeActivity-debug.apk
