android-jni 真实编译过程演示教学-adthree.doc

精这章是高级篇恭喜您进入高级阶段！时间：2010-11-30版本：v1.12问题：如何来进行JNI的编程呢？过程是如何样呢？所谓神马都是有解决方法的小哈做如下解：首先你肯定要有一个编译环境啦亮出我们本次的主角：ubuntu 10开始，是通过GIT 得到ANDROID源码，有了源码我们能做什么？打广告？写程序打广告赚钱？NO我们本次是要做JNI学会了JNI，才能更好地写程序打广告赚钱:D童鞋们有什么好的建议及问题就请联系大家一起交流本文章使用的环境是：UBUNTU 10 + G1 QQ群为：10334534 联系EMAIL: ericlzyu# (请把#换成)三人广告（ ）致力于为应用开发者提供一个宣传与盈利的平台，帮助开发者让更多的用户使用到您的服务让产品良性发展，让生活更娱乐，更美好三人广告真诚邀请您与我们合作，我们愿意帮助开发者在移动互联网领域携手并进共创美好未来好了，不罗嗦了，接下来就是漫长的等待华丽地等待等待着YY的到来终于编译完成了看到在BUILD目录下有个 envsetup.sh ，执行它看好了，使用：/build$ . envsetup.sh把环境搭建好之后实验在development/samples/SimpleJNI/ 目录下。执行： mm好了接下来的就是编译SimpleJNI项目的过程了要看好别走神了！coconutubuntu:/android$ mm development/samples/SimpleJNI/AndroidManifest.xml Android.mk jni/ src/ coconutubuntu:/android$ mm development/samples/SimpleJNI/=PLATFORM_VERSION_CODENAME=AOSPPLATFORM_VERSION=AOSPTARGET_PRODUCT=genericTARGET_BUILD_VARIANT=engTARGET_SIMULATOR=TARGET_BUILD_TYPE=releaseTARGET_ARCH=armHOST_ARCH=x86HOST_OS=linuxHOST_BUILD_TYPE=releaseBUILD_ID=MASTER=* Build configuration changed: generic-eng-sdk-mdpi -
