android-jni 真實編譯過程演示教學(xué)-adthree.doc

精這章是高級篇恭喜您進入高級階段！時間：2010-11-30版本：v1.12問題：如何來進行JNI的編程呢？過程是如何樣呢？所謂神馬都是有解決方法的小哈做如下解：首先你肯定要有一個編譯環(huán)境啦亮出我們本次的主角：ubuntu 10開始，是通過GIT 得到ANDROID源碼，有了源碼我們能做什么？打廣告？寫程序打廣告賺錢？NO我們本次是要做JNI學(xué)會了JNI，才能更好地寫程序打廣告賺錢:D童鞋們有什么好的建議及問題就請聯(lián)系大家一起交流本文章使用的環(huán)境是：UBUNTU 10 + G1 QQ群為：10334534 聯(lián)系EMAIL: ericlzyu# (請把#換成)三人廣告（ ）致力于為應(yīng)用開發(fā)者提供一個宣傳與盈利的平臺，幫助開發(fā)者讓更多的用戶使用到您的服務(wù)讓產(chǎn)品良性發(fā)展，讓生活更娛樂，更美好三人廣告真誠邀請您與我們合作，我們愿意幫助開發(fā)者在移動互聯(lián)網(wǎng)領(lǐng)域攜手并進共創(chuàng)美好未來好了，不羅嗦了，接下來就是漫長的等待華麗地等待等待著YY的到來終于編譯完成了看到在BUILD目錄下有個 envsetup.sh ，執(zhí)行它看好了，使用：/build$ . envsetup.sh把環(huán)境搭建好之后實驗在development/samples/SimpleJNI/ 目錄下。執(zhí)行： mm好了接下來的就是編譯SimpleJNI項目的過程了要看好別走神了！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 -
