Modify the launcher icon of each of your app-variants using simple Gradle rules. Add ribbons of any color, overlay your own images, customize it according to your needs!

This library heavily relies on the original Akaita's easylauncher plugin, but introduces supports for modern build tools and Vector icons

Usage

Basic usage

// in app/build.gradle
plugins {
    id "com.starter.easylauncher" version "${{version}}"
}

see Gradle Plugin Portal for the details

// in root project's build.gradle 
buildscript {
    repositories.google()
}
plugins {
    id "com.starter.easylauncher" version "${{version}}" apply false
}

// in app/build.gradle 
plugins {
    id "com.starter.easylauncher"
}

Advanced usage

By default, the plugin applies green ribbon for all debuggable build variants. You can customize the filters applied to each type, flavor and variant of your app.

Imagine these are the type and flavors of your app:

// in app/build.gradle
android {
    buildTypes {
        debug {
            //Debuggable, will get a default ribbon in the launcher icon
        }
        beta {
            //Debuggable, will get a default ribbon in the launcher icon
            debuggable true
        }
        canary {
            //Non-debuggable, will not get any default ribbon
            debuggable false
        }
        release {
            //Non-debuggable, will not get any default ribbon
        }
    }
    productFlavors {
        local {}
        qa {}
        staging {}
        production {}
    }
}

You could customize the plugin's behaviour like this:

easylauncher {
    defaultFlavorNaming = true // Use flavor name for default ribbon, instead of the type name
    
    productFlavors {
        local {}
        qa {
            // Add one more filter to all `qa` variants
            filters redRibbonFilter()
        }
        staging {}
        production {}
    }
    
    buildTypes {
        beta {
            // Add two more filters to all `beta` variants
            filters = [
                    customRibbon(ribbonColor: "#0000FF"),
                    overlayFilter(new File("example-custom/launcherOverlay/beta.png"))
            ]
        }
        canary {
            // Remove ALL filters to `canary` variants
            enable false
        }
        release {}
    }
    
    variants {
        productionDebug {
            // OVERRIDE all previous filters defined for `productionDebug` variant
            filters = orangeRibbonFilter("custom")
        }
    }
}

Providing Icon Names

By default, the plugin automatically discovers launcher icon and applies provided filters.
Custom icon names, useful i.e. when defining multiple activity aliases, can be provided using iconNames property as follows:

easylauncher {
    iconNames = ["@mipmap/custom_launcher_icon"] // optional, disables automatic launcher icon discovery and will use provided icons only

    buildTypes {
        beta {
            // icon names can also be provided per each configuration (buildType, productFlavor or variant)
            iconNames = ["@mipmap/beta_launcher"]  
        }
    }
}

Available options

• defaultFlavorNaming: use flavor name in default ribbons, instead of using buildType
• enable: enable/disable all filters for a flavor/type/variant
• productFlavors: define filters for flavors (will be added to filters defined for types)
• buildTypes: define filters for types (will be added to filter defined for flavors)
• variants: define filters for variants (will override any other filters)
• iconNames: provides a list of icons which will have the filters applied

Requirements

Minimal requirements for the plugin are:

• Gradle: 6.1.1
• Android Gradle Plugin: 4.0.0
• minSdkVersion: 21 (theoretically there should be no lower boundary - it just hasn't been tested)
