一、ndk编译android上运转的c程序
新建个hello目录，底下要有jni目录，下面便是Android.mk文件
1.Android.mk文件内容如下:
LOCAL_PATH:= $(call my-dir)include $(CLEAR_VARS)LOCAL_SRC_FILES:= hello.cLOCAL_MODULE:= helloLOCAL_FORCE_STATIC_EXECUTABLE := true#LOCAL_STATIC_LIBRARIES := libc#LOCAL_CFLAGS += -Iinclude/dir -DSOMEFLAGSinclude $(BUILD_EXECUTABLE)
2.jni下新建个hello.c，内容取自kanxue论坛上的一份代码:
#include#include int main(int argc,char *argv[]){char name[]="helloworld";int keys[]={0xb,0x1f,0x19,0x19,0x49,0xb,0xb,0xb,0x31,0x53};char Thekeys[11];int i;for(i=0;i<10;i++){keys[i]^=7;keys[i]=keys[i]/6;keys[i]+=22;keys[i]-=24;keys[i]^=name[i];}for(i=0;i<10;i++){Thekeys[i]=keys[i];}Thekeys[i]=0;if(!strcmp(Thekeys,argv[1]))printf("Good Work,you have Successed!");elseprintf("NO,you are failed!");return 0;}
3.编译

二、ARM crackme学习
ARM开端完结，开端以crackme操练作为学习的意图
