# 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`
