我的方法数没有超过65535，但是我想要分包，请问怎么操作？

dexknife.txt
#为注释符

#-----------主Dex中必要依赖的脚本配置-----------
#默认保留四大组件中其他三大组件(并计算其依赖树)，Activity组件选择性保留(使用-just activity 选项),若为空不保留任何Activity
-just activity com.juziwl.ixiao.main.MainActivity

#-----------附加类-----------

如果你想要某个包路径在maindex中，则使用 -keep 选项，即使他已经在分包的路径中.若为空，不保留任意类

#-keep com.ceabie.demo.**

保留单个类.

#-keep android.support.v7.app.AppCompatDialogFragment.class

这条配置可以指定这个包下类在第二及其他dex中.

#-split android.support.v?.**
#将全部类移出主Dex
-split .

不包含Android gradle 插件自动生成的miandex列表.(不使用建议的依赖树，注释掉表示使用,否则-just activity无效)

#-donot-use-suggest

(分割每个dex的方法数上限) 扩展参数:例如 --set-max-idx-number=50000

如果出现 DexException: Too many classes in --main-dex-list, main dex capacity exceeded：

表明限制的方法数小于main dex的必要方法数，调大到合适数值即可

-dex-param --set-max-idx-number=3000

不进行dex分包， 直到 dex 的id数量超过 65536.(设置自动执行分包策略)

#-auto-maindex

显示miandex的日志.

#-log-mainlist

打包的时候还报了一些错，但是打包成功了

我生成class.dex文件有27928个方法，我现在就想分包，请问怎么写？还有上面的问题是什么原因造成的？

[TangXiaoLv]

@Armyoftheworld
1.这个错是编译环境造成的，并非打包。
2.合理设置-dex-param --set-max-idx-number=4000（每个dex最大方法数，这个值必须>main dex必须的方法数）
3.如果studio是2.0+ 确保把instant run关掉，否则打debug包会默认禁用分包功能，由于instant run的机制自动做了增量分包

[Armyoftheworld]

请问从哪里知道main dex必须的方法数？因为我不知道那些类会在main dex中？
我已经把instant run关掉了，还是没有分包。

[Armyoftheworld]

还有我想问一下，分包的话是不是默认会混淆，因为我这边一打包就会报混淆时出的错误，我已经在release里面把minifyEnabled设为false了

[TangXiaoLv]

@Armyoftheworld 默认不会混淆，混淆不影响分包

[Armyoftheworld]

@TangXiaoLv 关于还是不能分包的问题，请问通常是怎么判断main dex需要的方法数？

[TangXiaoLv]

首次默认运行查看main dex 方法数，然后根据方法数向上取整得出每个dex的方法树，通常默认就好了，只限制main dex的，其他的分包超过65535再自动分。

[Armyoftheworld]

我想知道为什么你的demo都没有分包？是我这边的问题吗？我的android studio是2.2的，gradle版本是2.2的，instant run已经关了。

[TangXiaoLv]

@Armyoftheworld 我本地测试OK的 Gradle version 2.14.4 .Plugin Version 2.2.2

[ibrothergang]

@Armyoftheworld demo后来能分包吗？我这边始终有问题。

[Armyoftheworld]

@wanggang1984117 不能，我也没有继续弄
