Windows下 ndk 編譯程序

環境變量添加 Android 相關設置：

ANDROID_HOME   C:\Users\zhanghb\AppData\Local\Android\Sdk

ANDROID_NDK       C:\Users\zhanghb\AppData\Local\Android\Sdk\ndk\21.1.6352462

創建一個源碼目錄hello

1. 創建子目錄 jni

2. 在 jni 目錄創建2個文件，hello.c 和 Android.mk

hello.c

#include <stdio.h>
int main()
{
    printf("Hello World!\n");
    return 0;
 
}

Android.mk

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES:=hello.c
LOCAL_MODULE := helloworld
LOCAL_MODULE_TAGS := optional
include $(BUILD_EXECUTABLE)

3. 開始編譯

進入 hello 目錄，執行：

>set NDK_PROJECT_PATH=.
>ndk-build
Android NDK: APP_PLATFORM not set. Defaulting to minimum supported version android-16.
