android studio 版本控制

前言

用AS开发项目，依赖了多个Module,我们需要保持 module和app的版本是一致的，所以我们借鉴Google 开源项目的做法
在Project build 里面加入

ext {
    // Sdk and tools
    minSdkVersion = 10
    targetSdkVersion = 24
    compileSdkVersion = 24
    buildToolsVersion = '24.0.2'

    // App dependencies
    supportLibraryVersion = '24.2.0'
    guavaVersion = '18.0'
    junitVersion = '4.12'
    mockitoVersion = '1.10.19'
    powerMockito = '1.6.2'
    hamcrestVersion = '1.3'
    runnerVersion = '0.5'
    rulesVersion = '0.5'
    espressoVersion = '2.2.2'
    daggerVersion = '2.7'
    dexmakerVersion = '1.2'
}

然后在App build 文件里加入,按照下面的模板就可以了。

   compileSdkVersion rootProject.ext.compileSdkVersion
   buildToolsVersion rootProject.ext.buildToolsVersion

   compile "com.android.support:appcompat-v7:$rootProject.supportLibraryVersion"
   compile "com.android.support.test.espresso:espresso-idling-resource:$rootProject.espressoVersion"
   compile "com.google.guava:guava:$rootProject.guavaVersion"

    // Dagger dependencies
   apt "com.google.dagger:dagger-compiler:$rootProject.daggerVersion"
   provided 'org.glassfish:javax.annotation:10.0-b28'
   compile "com.google.dagger:dagger:$rootProject.daggerVersion"
