build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.myapplication"
        minSdkVersion 15
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
        manifestPlaceholders = [label: "defaultName"]
        manifestPlaceholders = [mapKey: "your_debug_key"]

    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            manifestPlaceholders = [mapKey: "your_release_key"]
        }
    }
    productFlavors {

        flavor1 {
            manifestPlaceholders = [label: "flavor1"]
        }
        flavor2 {
            manifestPlaceholders = [label: "flavor2"]
        }
        flavor3 {
            manifestPlaceholders = [label: "flavor3"]
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

Can you provide more information about what the result would be for the different build types and flavors? For example, do the label placeholders in the different flavors override the one specified in defaultConfig? What if I specified a placeholder for label in the release buildType? Would that get overridden by the flavors, or will the buildType placeholder always take precedence?

I ask all this because I'm trying to do something similar to what you have laid out in code, but I'm having a lot of trouble understanding how to get manifestPlaceholders to work the way I want.

Thanks.

use gradle2.6 this segment dones't work

@zhEdward, in newer version, manifestPlaceholders is a map. So you should use it as folllowing

manifestPlaceholders = [label: "defaultName", mapKey: "your_debug_key"]

@baole yes it's thanks :)

Do manifestPlaceholders work when declared in a library module? So could i define the manifestPlaceholders in my library module and then would the consuming application would use those place holders?

Thanks, it was helpful!
