上一篇博客，将1.8.1这个版本移植到了Android平台，无奈着不是官方版本，不太完美。这次尝试为Android平台构建1.9版本（注意这是个不稳定版本，1.9官方没有正式Release）。

依赖库官方已经移植好了，直接下载下来就可以了。

地址 http://sourceforge.net/projects/ogre/files/ogre-dependencies-android/1.9/AndroidDependencies.zip/download

具体的移植步骤，请看这里的官方文档，很详细了。我就说几个移植中需要注意的地方。

Android NDK我选的是官方的android-ndk-r8d，顺利的移植了，其他版本无一幸免都有无法检测编译机器类型的错误，应该是Ogre使用的android-cmake版本的问题，具体我没有细究。

环境变量ANDROID_NDK别忘了，这个是android-cmake脚本要用到的。

编译出来的，SampleOgreBrowserNDK这个安装包的resources.cfg有点小问题，我做了点修改，修改如下：

# Resources required by the sample browser and most samples.
[Essential]
APKZip=/packs/SdkTrays.zip
APKFileSystem=/thumbnails

# Common sample resources needed by many of the samples.
# Rarely used resources should be separately loaded by the
# samples which require them.

APKFileSystem=/fonts
APKFileSystem=/materials/programs

APKZip=/packs/ogretestmap.zip
APKZip=/packs/ogredance.zip

编译出来的库都是静态链接的，一堆依赖，稍不留神就出问题，可能本人水平不够吧。

写了个测试程序，SampleBrowser这个项目一堆#ifdef，看着真心头疼，自己写了个简单的Android测试程序。

使用了NativeActivity，所以不用写一行Java代码。(NativeActivity Android NKD中有个例子，代码不明白的话可以参考一下）。接着是Android.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

include $(BUILD_SHARED_LIBRARY)

$(call import-module, android/native_app_glue)
$(call import-module, android/cpufeatures)

Application.mk文件：

APP_ABI := armeabi
APP_STL := gnustl_static

为了使用NativeActivity，AndroidManifest.xml得改一下，要不然系统不能识别到NativityActivity

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="cloud.example.andogre"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

      <-- 无java代码 -->

      <application android:allowBackup="true" android:label="@string/app_name" android:hasCode="false">

        <-- 这里，告诉系统Activity是NativeActivity -->
        <activity android:name="android.app.NativeActivity"
                android:label="@string/app_name"
                android:configChanges="orientation|keyboardHidden"
                android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >
            <!-- Tell NativeActivity the name of or .so -->
            <meta-data android:name="android.app.lib_name"
                    android:value="andogre" />
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

以上就是全部内容。欢迎指正
