  1. Configure Environment VariablesAdd the Make tool PATH environment variable:

E:\Android\android-ndk-r10b\prebuilt\windows-x86_64\bin


   2. Write Hello worldNew HELLO.C
#include <stdio.h>int main (intChar* argv[]) {  printf ("  Hello android!\r\n");   return 0 ;}

3. Write the makefile file as follows
#ndk根目录NDK_ROOT=e:\android\android-ndk-r10b# Compiler root directory toolchains_root=$ (ndk_root)/toolchains/arm-linux-androideabi-4.6/prebuilt/windows-x86_64# Compiler directory Toolchains_prefix=$ (toolchains_root)/bin/arm-linux-androideabi# Header File search path Toolchains_include=$ (toolchains_root)/lib/GCC/arm-linux-androideabi/4.6/include-fixed#sdk root directory platfrom_root=$ (ndk_root)/platforms/android- -/arch-arm#sdk Header File search path Platfrom_include=$ (platfrom_root)/usr/INCLUDE#SDK Library File search path Platfrom_lib=$ (platfrom_root)/usr/lib# file name Modale_name=hello# Delete rm=del# Compile Options flags=-i$ (toolchains_include)-i$ (platfrom_include)-l$ (platfrom_lib)-nostdlib-LGCC-bdynamic-lc# all obj files Objs=$ (modale_name).

   4. Use the make command to compile the program
 generate a target file that can execute a file Hello hello.oSo there are commands to compile the NDK:
//compiling the target filee:\android\android-ndk-r10b/toolchains/arm-linux-androideabi-4.6/prebuilt/windows-x86_64/bin/arm-linux-androideabi-gcc-ie:\android\android-ndk-r10b/toolchains/ arm-linux-androideabi-4.6/prebuilt/windows-x86_64/lib/gcc/arm-linux-androideabi/4.6/include-fixed-ie:\android\android-ndk-r10b/platforms/android- -/arch-arm/usr/include-le:\android\android-ndk-r10b/platforms/android- -/arch-arm/usr/lib-nostdlib-lgcc-bdynamic-lc-c hello.c-o hello.o//compile to execute filee:\android\android-ndk-r10b/toolchains/arm-linux-androideabi-4.6/prebuilt/windows-x86_64/bin/arm-linux-androideabi-gcc-ie:\android\android-ndk-r10b/toolchains/ arm-linux-androideabi-4.6/prebuilt/windows-x86_64/lib/gcc/arm-linux-androideabi/4.6/include-fixed-ie:\android\android-ndk-r10b/platforms/android- -/arch-arm/usr/include-le:\android\android-ndk-r10b/platforms/android- -/ARCH-ARM/USR/LIB-NOSTDLIB-LGCC-BDYNAMIC-LC hello.o e:\android\android-ndk-r10b/platforms/android- -/ARCH-ARM/USR/LIB/CRTBEGIN_DYNAMIC.O e:\android\android-ndk-r10b/platforms/android- -/arch-arm/usr/lib/crtend_android.o-o Hello
5. Running the programYou can also use makefile
 Install and run our program with make installuse make run to run our program install and run can be understood as custom functions in Makefile
