How to use NDK? Starting with 'hello world' app

Question

I would like to see a \'Hello world\' program written in C/C++ but made to run on Android.

I know this is possible by using NDK and JNI calls. But not able to make i

Answer 1

Install the SDK and NDK like this: https://askubuntu.com/a/732010/52975

Plug in your device via USB and run:

git clone https://github.com/googlesamples/android-ndk
cd android-ndk
git checkout a5fdebebdb27ea29cb8a96e08e1ed8c796fa52db
cd hello-jni
./gradlew clean
./gradlew assembleDebug
./gradlew installAllDebug

Now the app should be installed in your device.

hello-jni is the simplest C example, and there are also C++ examples like Teapot.

Those examples use Gradle, and there are Ant Android.mk examples under the branch android-mk. You can build those with:

 ndk-build
 android update project -p . -t android-23
 ant clean
 ant debug
 ant installd
