How to use com.android.databinding in module(Android studio)?

Question

I want create a library using com.android.databinding: dataBinder .

build.gradle for project:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath 'com.android.databinding:dataBinder:1.0-rc4'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
        //gradlew -Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=8580
    }
}


task clean(type: Delete) {
    delete rootProject.buildDir
}

build.gradle for module :

apply plugin: 'com.android.library'  // apply plugin: 'com.android.application'
apply plugin: 'com.android.databinding'


android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"
    aaptOptions {
        additionalParameters "--no-version-vectors"
    }

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 23
        versionCode 1
        versionName "1.1"
        multiDexEnabled true
        generatedDensities = []
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.0'
    compile 'com.jakewharton:butterknife:7.0.1'
    compile 'com.android.support:support-v4:23.2.0'
 }

I change apply plugin: 'com.android.application' to apply plugin: 'com.android.library' .But when I changed the code to the following error occured.

Error this :

Answer 1

Follow the guide here:

http://developer.android.com/tools/data-binding/guide.html

You must add dataBinding.enabled = true to the android section. You should also use android gradle plugin 1.5.0 or later.

You don't need the apply plugin: 'com.android.databinding' anymore either. Data binding is now included into the android gradle plugin.

Answer 2

Only add

android {
    ...
    dataBinding {
        enabled = true
    }
}

if you are using gradle 2.0 or later. for example:

classpath 'com.android.tools.build:gradle:2.3.0'
