# How to compile C++ hello world with Android NDK
1. Create following directory structure:
```
hello_world/
jni/
libs/
```
2. In the `jni` directory create two files
1. Android.mk:
```
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# give module name
LOCAL_MODULE := hello_world
# list your C files to compile
LOCAL_SRC_FILES := test.c
# This seems to be needed for Android M on ARMv8
LOCAL_CFLAGS = -fPIE
LOCAL_LDFLAGS = -fPIE -pie
include $(BUILD_EXECUTABLE)
```
2. test.c
```
#include <stdio.h>
#include <stdlib.h>
int main()
{
printf("Hello World\n");
return 0;
}
```
4. Export PATH to NDK
```
export PATH=/usr/local/softs/android-ndk-r10e:$PATH
```
3. Go to `jni` directory
5. Call ``ndk-build``
6. Result should be in `hello_world/libs/armeabi/hello_world`
