No excuses, dude. You just have to read (take a look at the Exploring the hello-jni Sample section).

Answer 4

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
