    }
    // 引用配置文件
    apply from: 'config.gradle'
    dependencies {
        classpath externalAndroidBuildGradlePlugin
        // 引用 com.tencent.bugly
        classpath 'com.tencent.bugly:symtabfileuploader:latest.release'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        google()
        jcenter()
        maven { url "http://maven.aliyun.com/nexus/content/repositories/releases" }
        flatDir { dirs 'src/main/libs' }
    }
    apply plugin: 'idea'
    // 指定编译临时文件存放地址, buildDir和rootDir，是gradle中的内置变量
    buildDir = new File(rootDir, "gradle-build/${path.replaceAll(':', '/')}")
}
task wrapper(type: Wrapper) {
    gradleVersion = '4.2.1'
}
task clean(type: Delete) {
    delete rootProject.buildDir
}

上面是在Project/build.gradle中进行配置，在Module/build.gradle中还需要进行引用。

apply plugin: 'bugly'
bugly {
    appId = '...' // 注册时分配的App ID
    appKey = '...' // 注册时分配的App Key
    debug = true
}

使用aar文件

新建Module的时候，选择Import .jar/.aar Package，选择aar文件后会自动生成比如下面这样的一个gradle文件。

configurations.maybeCreate("default")
artifacts.add("default", file('AlivcPlayer-3.4.8.aar'))
