Configuring Gradle Builds

This section builds on the Build System Overview and Build and Running from Android Studio to show you how to use build variants based on product flavors and build types.

Build Configuration Basics

---

Android Studio projects contain a top-level build file and a build file for each module. The build files are called build.gradle, and they are plain text files that use Groovy syntax to configure the build with the elements provided by the Android plugin for Gradle. In most cases, you only need to edit the build files at the module level. For example, the build file for the app module in the BuildSystemExample project looks like this:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile project(":lib")
    compile 'com.android.support:appcompat-v7:19.0.1'
    compile fileTree(dir: 'libs', include: ['*.jar'])
