• در مرحله آماده سازی ما به گریدل می‌گوییم چه پروژه یا پروژه‌هایی نیاز به بیلد شدن دارند. در اندروید استادیو،  این مرحله در فایل settings.gradle انجام می‌شود؛ شما در این فایل مشخص می‌کنید چه پروژه‌های نیاز به بیلد شدن توسط گریدل دارند. ساختار این فایل به این شکل است:

include ':ActiveAndroid-master', ':app', ':dbutilities'

1. در اولین مرحله انتظار دارد که فایل settings در دایرکتوری جاری باشد و اگر آن را پیدا کرد آن را مورد استفاده قرار می‌دهد؛ در غیر اینصورت مرحله بعدی را آغاز می‌کند.
   
2. در مرحله دوم،  در این دایرکتوری به دنبال دایرکتوری به نام master میگردد و اگر در آن هم یافت نکرد مرحله سوم را آغاز می‌کند.
3. در مرحله سوم، جست و جو در دایرکتوری والد انجام می‌شود
4. چنانچه این فایل را در هیچ یک از احتمالات بالا نیابد، همین پروژه جاری را تشخیص خواهد داد.

include ':ActiveAndroid-master', ':app', ':dbutilities'
project('dbutilities').projectDir=new File(settingsDir,'../dir1/dir2');

• در مرحله پیکربندی، وظایف یا task‌ها را معرفی می‌کنیم. این عمل پیکربندی توسط فایل build.gradle که برای پروژه اصلی و هر زیر پروژه‌ای که مشخص شده‌اند، صورت می‌گیرد. در این فایل شما می‌توانید خواص و متدهایی را تعریف و و ظایفی را مشخص کنید.
  در پروژه اصلی، فایل BuildGradle شامل خطوط زیر است:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
    }
}

allprojects {
    repositories {
        jcenter()

    }
}

    println ".net tips task in config phase"

    doLast{

    }
}

task mytask1 << {
    println ".net tips is the best"
}

task mytask2() {
    dependsOn mytask1

    doLast{
        Date time=Calendar.getInstance().getTime();
        SimpleDateFormat formatter=new SimpleDateFormat("HH:mm:ss , YYYY/MM/dd");
        println "mytask1 is done at " + formatter.format(time);

    }
}
