在所有库中导入应用程序compat依赖项 [英] Import app compat dependency in all libraries

问题描述

我在我的应用程序中有两个模块，我想修改它们两个以使用AppCompat Widgets，我必须使用它们对它们进行扩展。问题是我不想为它们中的每一个添加appcompat依赖项，所以我怎么可能将Dependency添加到模块和我的应用程序。如果我添加

  compile'c​​om.android.support:appcompat-v7:23.1.1'
 
 code> 

到每个模块，会影响应用程序的大小吗？


解决方案

使用

  compile'c​​om.android.support:appcompat-v7:23.1.1' 
  

在每个模块中并不意味着将其添加两次或更多次。

Gradle处理它只为您添加一次库。

使用多模块项目，您可以将支持库依赖集中在gradle中。

一个很好的方法是分离gradle构建文件，定义如下所示：

  root 
 --gradleScript 
 ---- dependencies.gradle 
 --module1 
 ---- build。 gradle 
 --module2 
 ---- build.gradle 
 --build.gradle 
  

在 gradleScript / dependecies.gradle 中：

  ext {
 //版本
 supportLibrary = '23 .2.0'
 
 / /支持库依赖关系
 supportDependencies = [
 design：com.android.support:design:${supportLibrary}，
 recyclerView：com.android.support:recyclerview-v7:$ {supportLibrary}，
 cardView：com.android.support:cardview-v7:${supportLibrary}，
 appCompat：com.android.support:appcompat-v7:${supportLibrary} ，
 supportAnnotation：com.android.support:support-annotations:${supportLibrary}，
] 
} 
  

在顶层文件 build.gradle 中：

  //顶层构建文件，您可以在其中添加对所有子项目/模块通用的配置选项。 
 buildscript {
 repositories {
 jcenter（）
} 
依赖关系{
 classpath'com.android.tools.build:gradle:1.5.0' 
 
 
 
加载依赖关系
应用于：'gradleScript / dependencies.gradle'
  

$ b $ module1 / build.gradle ：

  //模块构建文件
 
依赖关系{
 // ...... 
编译supportDependencies.appCompat 
编译supportDependencies.design 
} 
  

I have 2 modules in my application, I want to modify both of them to use AppCompat Widgets for which I have to extend them with same. The problem is that I do not want to add appcompat dependency to each of them, So how could I possibly add Dependency to both modules and my app. If I do add

compile 'com.android.support:appcompat-v7:23.1.1'

to every module, would it affect the application size?

解决方案

Using

compile 'com.android.support:appcompat-v7:23.1.1'

in every module doesn't mean to add it twice or more times.

Gradle handles it for you adding the library only one time.

Working with multi-modules project, you can centralize the support libraries dependencies in gradle.

A very good way is to separate gradle build files, defining something like:

root
  --gradleScript
  ----dependencies.gradle
  --module1
  ----build.gradle
  --module2
  ----build.gradle
  --build.gradle

In gradleScript/dependecies.gradle:

ext {
    //Version
    supportLibrary = '23.2.0'

    //Support Libraries dependencies
    supportDependencies = [
            design           :         "com.android.support:design:${supportLibrary}",
            recyclerView     :         "com.android.support:recyclerview-v7:${supportLibrary}",
            cardView         :         "com.android.support:cardview-v7:${supportLibrary}",
            appCompat        :         "com.android.support:appcompat-v7:${supportLibrary}",
            supportAnnotation:         "com.android.support:support-annotations:${supportLibrary}",
    ]
}

In the top level file build.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
    }
}

// Load dependencies
apply from: 'gradleScript/dependencies.gradle'

In the module1/build.gradle:

// Module build file

dependencies {
    //......
    compile supportDependencies.appCompat
    compile supportDependencies.design
}
