Android 在所有库中导入应用程序兼容性依赖项

我的应用程序中有两个模块，我想修改这两个模块以使用AppCompat小部件，我必须用相同的扩展它们。问题是，我不想将appcompat依赖项添加到它们中的每一个，因此我如何可能将依赖项添加到模块和我的应用程序中。如果我加上

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

对于每个模块，它会影响应用程序大小吗？

使用

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

在每个模块中，并不意味着添加两次或更多次

Gradle只为您添加一次库

使用多模块项目，您可以在gradle中集中支持库依赖项

一个很好的方法是分离gradle构建文件，定义如下内容：

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

在

gradleScript/dependecies.gradle

中：

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}",
    ]
}

// 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'

// Module build file

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