Building and running app via Gradle and Android Studio 2.0 is slower

Question

I have a multi-project (2 modules) of which building takes about 1/2 min each time. When I press Run in Android Studio, I have to wait every time to rebuild the app, which is extremely slow. It's took 6/8 min each time.

Is it possible to automate building process in Android Studio? Or do you have any advice on how to make this process faster?

here is my build.gradle file (app module):

allprojects {
    repositories {
        mavenCentral()
        maven {  url "https://jitpack.io" }
        maven { url 'http://clinker.47deg.com/nexus/content/groups/public' }
    }
}

apply plugin: 'com.android.application'

dependencies {
    compile 'com.dlazaro66.qrcodereaderview:qrcodereaderview:1.0.0'
    compile fileTree(dir: 'libs', include: '*.jar')

    productFlavors {

    afterEvaluate {
        tasks.matching {
            it.name.startsWith('dex')
        }.each { dx ->
            if (dx.additionalParameters == null) {
                dx.additionalParameters = []
            }
            dx.additionalParameters += '--multi-dex'

        }
    }
   } 

My notebook spects are I3 8GB RAM and Windows 10 64bits

Actually I have Android Studio 2.0 preview 9 with this studio64.exe.vmoptions

-Xms256m
-Xmx1280m

-Didea.paths.selector=AndroidStudioPreview2.0

And The Gradle work is OFFLINE

Answer 1

You should use Android Studio 1.5.1 which is much faster than prior version of Android Studio.
