使用 Android NDK 编译 Lua

启动 Android Studio ,创建一个 Android 项目，勾选 C++ Support。

未分类

一路 Next 到这里，直接 Finish，不用勾选保持默认即可。

如果之前没有安装 NDK 和 Cmake 工具，到这里会提示安装 NDK 等工具，直接安装，我这里之前已经安装了，所以略过。

等待工程就绪之后，正常构建一次，看 Hello World 能不能正常构建运行起来。查看编译后的 APK 文件，看看里面是否有下列目录和 .so 文件。

通过 7-Zip 可以查看 APK 里面的文件组成结构，如下是 lib 目录下的内容，分别对应不同的 CPU 架构。

如果能到这一步，说明至少 Android Studio 配置基本是 OK 的，NDK 能正常工作。

在 Android Studio 3.1 后，Gradle Console 就不见了，要查看构建过程和步骤，在 Build 窗口点击 Toggle View 就可以查看构建步骤了。

在 Project 面板中，CPP 目录下的文件就是 C/CPP 的源文件目录，我们从 Lua 官网下载源码后，将 .c 和 .h 文件当道这个目录下面。

未分类

目前我能下载到最新的 Lua 版本是 5.3.5 ，粘贴到 CPP 目录后，文件并不会显示，不知道这是不是 Android Studio 的 bug，接下来修改 CMakeLists.txt 里面的内容，将源代码增加到构建列表。

提示中说的也比较清楚，我们使用了已经废弃了的函数：warning: ‘tmpnam’ is deprecated: tempnam is unsafe, use mkstemp or tmpfile instead，但是项目中，使用这个 tmpnam 的比较多，而且需要改 Lua 源代码，本着不对 Lua 改动的原则，我们在 CMakeLists.txt 中增加下面的一行代码，屏蔽废弃函数的错误警告。

add_definitions(-Wno-deprecated)

在这个错误里，有两处非常明显：

error: CMakeFiles/luajit.dir/src/main/cpp/luac.c.o: multiple definition of 'main'
CMakeFiles/luajit.dir/src/main/cpp/lua.c.o: previous definition here

事实上，我们也不需要 Main 函数的定义，因为编译为 SHARE_LIBRARY ，所以屏蔽这个文件即可。

这次的错误都是这一个：undefined reference to ‘localeconv’，解决办法是提高 API Level ，我们把它改为 21 以上就可以解决这个问题。

再次构建，终于不再报错了，结果如下：

再生成 APK，使用 7-ZIP 查看 APK，就可以看到我们 Lua 已经稳妥妥的在 APK 安装包中了，达到 340 KB了，对于 so 库来说也不小了。

未分类

至此，Lua 已经编译好了，如果需要使用，还需要写 JNI 方法调用，不过那是后话了。

Android使用Jenkins自动化构建测试打包apk

Jenkins这东西搭建起来真是一点也不省心啊，看着别人的教程摸着石头过河，配置的东西有点多啊，稍有不慎，就构建不成功啦！即使步骤跟别人一样也会报各种乱七八糟的错误啊哈哈~~这东西只能佛系搭建~~在经历几十次的随缘构建之后，终于构建成功啦~~好感人！眼泪掉下来。。。。。。在此做下记录，造福广大群众！阿弥陀佛~~废话少说，且看如下操作：

下载Jenkins并安装

我们下载如图所示Window版本，下载下来是个.zip的压缩包，我们解压一下得到如下图所示文件：

双击即可开始安装，一直Next，即可安装完成。

环境变量配置

  • Java环境配置
  • Android SDK环境配置

右键此电脑-属性-高级系统设置-环境变量

在系统变量中添加 ：

变量名 JAVA_HOME

变量值 E:Javajdk8 （路径根据自己实际的java安装目录选择）

变量名 ANDROID_HOME

变量值 E:AndroidSDK （路径根据自己实际的java安装目录选择）

未分类

然后在系统的Path变量中添加 ：%Java_Home%bin

未分类

以上是Java环境的基本配置，作为一名Android开发攻城狮应该都知道基本操作。接下来就是重头戏啦！！！

Jenkins配置

安装完jenkins一般会自动在浏览器中打开，没有的话在浏览器输入 localhost:8080 或者 127.0.0.1:8080 页面出来后会提示选择安装插件，第一个是默认推荐的插件，第二个是自己选择要安装的插件

未分类

我们直接选默认的就好，点击第一个坐等jenkins自动安装插件

未分类

插件安装后需要创建你的账号

未分类

创建完就可以登录Jenkins控制台啦！

未分类

点击左侧 系统管理-系统设置

未分类

来到如下设置页面：

未分类

点开主目录右边的高级设置，修改一下工作空间根目录(路径任意，自己知道就行)，若不改，aapt编译时会报错，因为windows版本默认的根目录在C盘底下路径过长

未分类

往下拉配置全局属性，勾选环境变量，添加如下键值对

未分类

为什么说GRADLE_USER_HOME字段要固定写呢，因为要和Gradle的配置字段一致，否则编译会报错，如果这里不进行配置Gradle会使用默认的目录，会因为默认目录路径太长导致编译报错，是不是很坑！！！

未分类

配置完点击左下角保存按钮保存配置。

回到主页面点击左侧 新建任务

未分类

输入一个任务名称，选择构建一个自由风格的软件项目，点击确定

未分类

这样在 我的视图 里就能看到创建的任务啦，点击任务，进入任务详细页面

未分类

点击配置，进行构建前的详细配置，先配置普通项General，勾选Github prooject，设置远程仓库地址，以Github为例：

未分类

然后设置 源码管理 勾选Git，添加Github项目地址，你的Github账号密码

未分类

然后设置 构建触发器 （非必需设置）设置了只是多了一种构建方式，可以勾选 触发远程构建 ，然后设置一个身份验证令牌，即可通过浏览器访问链接触发构建

未分类

如红色方框所示，有两种拼接链接的方式触发构建，你可以在浏览器中输入 localhost:8080/me/my-views/view/all/job/Test/build?token=123456 或者 /buildWithParameters?token=123456 来触发构建。

也可以勾选Poll SCM，设置每隔一段时间自动构建，我设置了每小时构建一次，如下图所示

未分类

语法参考如下：

未分类

接下来设置 构建 点击增加构建步骤，选择Invoke Gradle script

未分类

勾选Invoke Gradle，选择gradle

未分类

Tasks 填写 clean build 命令

未分类

最后设置 构建后操作 点击增加构建后操作步骤，选择Archive the artifacts

未分类

填入正则表达式路径，匹配用于存档的apk

未分类

app/build/outputs/release/*.apk的意思是匹配app/build/outputs/release路径下所有拓展名为.apk的安装包，看这路径是不是很熟悉，其实就是项目路径下apk的输出路径

未分类

存档后Jenkins-release-v1.0.0.apk就会显示在Jenkins项目最后一次成功的构建结果

未分类

到此配置基本完成，是时候构建一波了，回到任务主页，点击立即构建

未分类

左下角会出现构建进度，蓝色圆点表示成功，红色圆点表示失败，点击构建序号，下拉选择控制台输出可以查看构建日志

未分类

未分类

至此，构建就大功告成啦！

在本地的JenkinsWork工作空间目录下可以看到从Github上拉取的项目源码

未分类

构建成功打包的apk在此目录下

未分类

接下来我们可以设置让构建打包好的apk自动发布到fir，详细教程请移步至http://blog.fir.im/jenkins文章写得很详细，我就不多说了。发布到fir后，平常测试人员找你要测试包，你可以对他说：“自己去fir下载。”一脸帅气.jpg

好了，今天就分享到这，祝大家Jenkins构建之路愉快！
