在 Android 的 ant 中启用 `--multi-dex` 选项
Enable `--multi-dex` option in ant for Android
为 gradle 构建系统启用 multi-dex 选项很容易,但我还没有找到如何为 ant 构建启用此选项的示例。如何存档?
我们有 2 个选择:
- 更改 DexExecTask [为多 dex 引入新参数],编译 ant.jar,使用此 jar 进行构建。我不喜欢这个选项,因为我们必须为所有团队成员提供更新 ant.jar。
- 修改项目build.xml 文件。我找到了很棒的 ant 构建文件,其中包含支持 multi-dex 的所有修改:https://github.com/ruboto/ruboto-irb/blob/master/build.xml
希望对您有所帮助。
我在基于Ruboto's build.xml (kudos to them!). So that's the path I would recommend to take. In that case you don't have to create custom ant jars, just edit your build.xml and apply all non-gradle steps from https://developer.android.com/tools/building/multidex.html
的使用ant的应用中引入了multi-dex支持
至于build.xml你得看看所有路径是否相互配合良好,你可能已经改变了其中的一些并且需要调整蚂蚁步骤。
在我的例子中,我还必须生成 类 的列表,这些列表必须放在第一个生成的 dex(默认)中,这样应用程序甚至可以在应用程序的 onCreate 中加载额外的 dexes 时启动。为此,您需要 运行 编写 mainDexClasses 脚本,您可以在构建工具中找到它:
mainDexClasses [--output <output file>] <application path>
Alex Lipov 写得很好 post 关于它。
当你生成 类 的列表时,你必须通过添加
在 dx 的参数中指向这个列表
<arg value="--main-dex-list="class_list_path" />
执行dx的地方。
值得记住的是,Ruboto 的脚本假定只会创建一个额外的 dex,但情况并非总是如此。我生成了两个额外的 dexe,所以我实现了添加(如果存在):
<if>
<condition>
<available file="${third_dex_path}"/>
</condition>
<then>
<exec executable="${aapt}" dir="${out.absolute.dir}" failonerror="true">
<arg line='add -v "${out.absolute.dir}/${resource.package.file.name}" ${third_dex}'/>
</exec>
</then>
</if>
Ant 中的 multidex 支持已启用!它不像 gradle 那样容易,但它是可能的。

我还在 ANT 构建中添加了 multidex,但方式略有不同,在 classes*.dex 支持中更加灵活。
无论如何,我分两个阶段完成此操作:1) 让 DX 输出 multidex,然后 2) 使用 aapt 包含 multidex classes。在这篇文章的末尾有一个生成主要 classes 列表的可选步骤,但对于基本实现来说不是必需的。
这是 build.xml 中的实现,后面有注释:

修改 (1) 替换了 -package 目标以允许将额外的 jar 传递给 ApkBuilder。事实证明,ApkBuilder 只是将 JAR 文件的内容复制到 APK 中,因此如果我们将 classes[1-N].dex 放入 JAR 中,我们可以让 ApkBuilder 将这些额外的 jar 打包到 APK 中。
(2) 使用除 classes.dex 之外的所有 classes*.dex 构建额外的 JAR 文件,因此支持任意数量的额外 classes.dex 文件
(3) 是解决 "dex" AntTask 不支持将 --multi-dex 传递给知道如何使用它的 "dx.bat" 的任何方式这一事实的变通方法。我查看了 dx.bat 调用的内容并直接在此处添加(修改:michaelbrz 在他的脚本中有更好的实现,所以我借用了它。谢谢)
顺便说一句,我们总是 运行 Proguard(混淆或未混淆)以获得 class 和方法收缩。这对于生成 "main class" 列表很方便。在我们的例子中,我们添加了 Google Play Services,这打破了我们的 DEX 文件方法限制,因此决定将这些 classes 和方法放在二级 dex 中。从 Proguard 输出生成 class 列表是一个简单的过滤问题 dump.txt:
<property name="multidex-main-dex-list.file"
value="bin/multidex-main-dex-list.txt" />
<target name="-create-multidex-main-list" if="${build.is.multidex}">
