A simple android gradle plugin to use the patterns of package to smart split the specified classes to multi dex.
Also supports android gradle plugin 2.2.0 multidex.
- Notes: Because instant-run of 2.0.0 above is incompatible with multidex, DexKnife is auto disabled when instant-run mode. It will auto enable when disabled instant-run or in packaging release.
###Update Log 1.5.6: Experimentally support java 1.7, fix nothing is selected when only -keep. (实验性的支持java 1.7,修复但只有keep选项时没有类被选中) 1.5.5: support individual filter for suggest maindexlist. (单独的maindexlist过滤设置) 1.5.5.alpha: Experimentally support android gradle plugin on 2.2.0. (实验性的支持 2.2.0 plugin) 1.5.4: auto disabled when instant run mode.(instant run 模式时自动禁用DexKnife) 1.5.3: add some track logs and skip DexKnife when jarMerging is null.(增加跟踪日志，并在jarMerging为null跳过处理) 1.5.2: fix the include and exclude path, and supports filtering single class.(修复include和exclude, 并支持过滤单个类) 1.5.1.exp: Experimentally support android gradle plugin on 2.1.0 （实验性的支持 2.1.0 plugin） 1.5.1: fix the proguard mode
###Usage 1.In your project's build.gradle, buildscript.
buildscript {
....
dependencies {
....
classpath 'com.android.tools.build:gradle:2.2.0-beta2' // or other
classpath 'com.ceabie.dextools:gradle-dexknife-plugin:1.5.6'
}
}
please make sure gradle version is compatible with the android gradle plugin, otherwise it can causes some sync error, such as:
Gradle sync failed: Unable to load class 'com.android.builder.core.EvaluationErrorReporter'.
2.Create a 'dexknife.txt' in your App's module, and config the patterns of classes path that wants to put into sencond dex.
Patterns may include:
'*' to match any number of characters
'?' to match any single character
'**' to match any number of directories or files
Either '.' or '/' may be used in a pattern to separate directories.
Patterns ending with '.' or '/' will have '**' automatically appended.
Also see: https://docs.gradle.org/current/javadoc/org/gradle/api/tasks/util/PatternFilterable.html
Note: if you want to filter the inner classes, use
Other config key:
'#' is the comment, config is disabled when '#' adds on line start.
# Global filter, don't apply with suggest maindexlist if -filter-suggest is DISABLE.
# this path will to be split to second dex.
android.support.v?.**
# if you want to keep some classes in main dex, use '-keep'.
-keep android.support.v4.view.**
# you can keep single class in main dex, end with '.class', use '-keep'.
-keep android.support.v7.app.AppCompatDialogFragment.class
# do not use suggest of the maindexlist that android gradle plugin generate.
-donot-use-suggest
# the global filter apply with maindexlist, if -donot-use-suggest is DISABLE.
-filter-suggest
# Notes: Split dex until the dex's id > 65536. --minimal-main-dex is default.
-auto-maindex # default is not used.
# dex additional parameters, such as --set-max-idx-number=50000
# if number is too small, it will cause DexException: Too many classes in --main-dex-list, main dex capacity exceeded
-dex-param --set-max-idx-number=50000
# log the main dex classes.
-log-mainlist
# log the filter classes of suggest maindexlist, if -filter-suggest is enabled..
-log-filter-suggest
# if you only filter the suggest maindexlist, use -suggest-split and -suggest-keep.
# Global filter will merge into them if -filter-suggest is ENABLE at same time.
-suggest-split **.MainActivity2.class
-suggest-keep android.support.multidex.**
3.add to your app's build.gradle, add this line:
apply plugin: 'com.ceabie.dexnkife'
and then, set your app
multiDexEnabled true
- Notes: You want to set 'multiDexEnabled true' in 'defaultConfig' or 'buildTypes', otherwise ineffective.
4.run your app
一个简单的将指定使用通配符包名分包到第二个dex中gradle插件。
同时支持 android gradle plugin 2.2.0 multidex.
- 注意：由于高于 2.0.0 的 instant-run 特性与 multidex不兼容，DexKnife会暂时禁用。当instant-run被禁用或者release打包时会自动启用。
###更新日志 1.5.6: 实验性的支持java 1.7,修复但只有keep选项时没有类被选中 1.5.5: 增加单独的maindexlist过滤设置 1.5.5.alpha: 实验性的支持 2.2.0 plugin 1.5.4: instant run 模式时自动禁用DexKnife 1.5.3: 增加跟踪日志，并在jarMerging为null时跳过处理 1.5.2: 修复include和exclude, 并支持过滤单个类 1.5.1.exp: 实验性的支持 2.1.0 plugin 1.5.1: fix the proguard mode
###使用方法 1.在你的工程的 build.gradle 中 buildscript:
buildscript {
....
dependencies {
....
classpath 'com.android.tools.build:gradle:2.2.0-beta2' // or other
classpath 'com.ceabie.dextools:gradle-dexknife-plugin:1.5.6'
}
}
注意，请确保使用的gradle版本和android gradle plugin兼容，否则会出现同步错误，例如：
Gradle sync failed: Unable to load class 'com.android.builder.core.EvaluationErrorReporter'.
2.在App模块下创建 dexknife.txt，并填写要放到第二个dex中的包名路径的通配符.
Patterns may include:
'*' to match any number of characters
'?' to match any single character
'**' to match any number of directories or files
Either '.' or '/' may be used in a pattern to separate directories.
Patterns ending with '.' or '/' will have '**' automatically appended.
更多参见: https://docs.gradle.org/current/javadoc/org/gradle/api/tasks/util/PatternFilterable.html
注意: 如果你要过滤内部类, 使用$*，例如: SomeClass$*.class
其他配置：
使用 # 进行注释, 当行起始加上 #, 这行配置被禁用.
# 全局过滤, 如果没设置 -filter-suggest 并不会应用到 建议的maindexlist.
# 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.
-keep android.support.v4.view.**
# 这条配置可以指定这个包下类在第二dex中.
android.support.v?.**
# 使用.class后缀，代表单个类.
-keep android.support.v7.app.AppCompatDialogFragment.class
# 不包含Android gradle 插件自动生成的miandex列表.
-donot-use-suggest
# 将 全局过滤配置应用到 建议的maindexlist中, 但 -donot-use-suggest 要关闭.
-filter-suggest
# 不进行dex分包， 直到 dex 的id数量超过 65536.
-auto-maindex
# dex 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，则需要调大数值
-dex-param --set-max-idx-number=50000
# 显示miandex的日志.
-log-mainlist
# 如果你只想过滤 建议的maindexlist, 使用 -suggest-split 和 -suggest-keep.
# 如果同时启用 -filter-suggest, 全局过滤会合并到它们中.
-suggest-split **.MainActivity2.class
-suggest-keep android.support.multidex.**
3.在你的App模块的build.gradle 增加：
apply plugin: 'com.ceabie.dexnkife'
最后，在app工程中设置：
multiDexEnabled true
- 注意：要在 defaultConfig 或者 buildTypes中打开 multiDexEnabled true，否则不起作用。
4.编译你的应用
