Reducing gradle build time android

Having multiple products flavors in android project can take it toll over build time. Below is the pro tip to force gradle to build only your desired build.

in your app.gradle

android{

….

…

if (project.rootProject.file('dev.props').exists()) {
    def devProps = new Properties()
    devProps.load(project.rootProject.file('dev.props').newDataInputStream())
    def currentDevFlavor = devProps.DEV_FLAVOR

    project.logger.lifecycle('preffered falvour ===>' + currentDevFlavor)

    android.variantFilter { variant ->

        def flavorName = variant.getFlavors().get(0).name +
                variant.getFlavors().get(1).name + buildType.name

        project.logger.lifecycle('Variant Flavor Name ==>' + flavorName)

        if (currentDevFlavor && (flavorName != currentDevFlavor)) {
            project.logger.lifecycle('Ignoring ==>' + flavorName)
            variant.setIgnore(true)
        } else {
            project.logger.lifecycle("Building..===>" + currentDevFlavor)
        }
    }
}

}

and create one file namely dev.props and add below line to it

DEV_FLAVOR= myappdevdebug //name of your desired build flavour with dimension
