最新首發Eclipse+CDT+android-ndk寫純c++安卓應用（附openGL Es）

首先下載eclipse和cdt，我的版本號碼依次是:Version: Indigo Service Release 2和Version: 1.0.0.201202111925，再下載windows的ndk，我使用的是android-ndk-r9d

什麼cygwin這等東西，太噁心了，下載慢，大的要命！複雜，今天給一個最爽的編譯教程。

前面的cdt外掛程式怎麼這裡pass，網上教程很多的。直接配置。。。

啟動eclipse，然後點Windows-Prefrences-C/C++-Build-Envionment，添加以下路徑

然後建立一個android工程，把代碼全部刪除，資源全部刪除，AndroidManifest.xml內容如下

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    package="com.example.native_activity"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="9"        tools:ignore="UsesMinSdkAttributes" />    <application        android:hasCode="false"        android:label="純CPP應用"        tools:ignore="AllowBackup,MissingApplicationIcon" >        <activity            android:name="android.app.NativeActivity"            android:configChanges="orientation|keyboardHidden" >            <!-- Tell NativeActivity the name of or .so -->            <meta-data                android:name="android.app.lib_name"                android:value="native-activity" />            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>    </application></manifest> 

然後建立jni目錄，裡面放三個檔案，依次是Android.mk

LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE    := native-activityLOCAL_SRC_FILES := main.cppLOCAL_LDLIBS    := -llog -landroid -lEGL -lGLESv1_CMLOCAL_STATIC_LIBRARIES := android_native_app_glueinclude $(BUILD_SHARED_LIBRARY)$(call import-module,android/native_app_glue)

Application.mk

APP_PLATFORM := android-14

main.cpp

建立完成收工，然後建立另外一個工程。路徑必須是剛才建立工程的jni目錄，名字隨便，重點看圖

好了點完成，然後開啟main.cpp發現N多錯誤，直接下設定一下環境變數，右鍵工程，屬性（是剛建立的C++工程）

接下來看圖，把所有的庫加進去。

最後加一個Symbol，其實就是定義一個宏，告訴編譯器我現在的平台是Android，add

最後點OK，所有的函數都能正常識別，提示功能也可以用了。開發效率高多了。編譯直接點鎚子就行了。

然後在原來的工程運行安裝就行了！
