Android Build Gradle Is Too Slow (Dependency Resolution)

Android build gradle is too slow (Dependency Resolution)

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 gradlecan 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 :

1. Make sure you have latest stable version ( current 2.0.0 )
2. Make sure your gradle version is 2.0.0 in build.gradle (classpath 'com.android.tools.build:gradle:2.0.0')
3. 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
}

Android Studio gradle takes too long to build

Found the reason!! If Android Studio has a proxy server setting and can't reach the server then it takes a long time to build, probably its trying to reach the proxy server and waiting for a timeout. When I removed the proxy server setting its working fine.

Removing proxy: File > Settings > Appearance & Behavior > System settings > HTTP Proxy

Android Studio stuck on gradle resolving dependencies

Killing the process or restarting the system helped me. Now it works perfectly fine...

P.S: A quote from the sitcom The IT Crowd:

Did you try turning it off and on again?

Slow build gradle in android

Try to update AndroidStudio to 3.0, upgrade gradle gradle:2.2.3 => gradle:3.0.0 and buildtools buildToolsVersion '25.0.2' => buildToolsVersion '26.0.2'
