Android build gradle is too slow (Dependency Resolution)

Question

I've been working with Android Studio (my current version 1.5) for 2 years. Everything was OK, but when I downloaded Canary (2.1 p5), everything went wrong. Every time I want to create a new project or open a project or sync or import a new lib or dependency, gradle is taking too long to build — nearly 20 min. I did not do anything, I just downloaded the Canary version and ran it. Symptoms : - It happened when I connected to Internet - The first delay is on Gradle: Resolve dependencies ':app:_debugCompile' - ... - After 25 min building almost done Note: When I disconnect my Internet, gradle will finish as fast as possible I tried to fix this by these ways: - I changed the gradle to offline work (it worked but I don't want this way, because I want to import libs or dependencies) I've created a new file (file name is `gradle.properties`) in `C:\Users\username\.gradle` then wrote these lines into it ``` org.gradle.parallel=true org.gradle.daemon=true ``` I removed that version then insta…

The problem is solved !

After 2 days searching , I got the solution , so I would like to share with all people who may have the same problem. The problem is `gradle`can not connect to center repository in some country. When you create a new project or import , your center repository is `jcenter()` by default and whenever you want to build or sync or add new external dependency, `gradle` is going to connect to https://bintray.com/ but it can not and the building process is going to wait till connect to `jcenter()`, so this process might take long time ( +30 min ) , even you can not add new dependency .

Solution :

- Make sure you have latest stable version ( current 2.0.0 )

- Make sure your gradle version is 2.0.0 in build.gradle (`classpath 'com.android.tools.build:gradle:2.0.0'`)

- Final step and most important one is change your jcenter() to mavenCentral()

So you can easily add new dependency and sync project under 3sec !

```
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0'

// NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
```
