Saya baru saja membuat proyek baru di Android Studio 3.2 Canary 16 dengan Kotlin diaktifkan. Lalu saya juga mengaktifkan data binding, tetapi saya mendapatkan error yang mengatakan bahwa class DataBindingComponent tidak dapat ditemukan.
Inilah proyek saya gradle:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
ext.kotlin_version = '1.2.41'
ext.android_plugin_version = '3.2.0-alpha10'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0-alpha16'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
File gradle modul saya:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 27
defaultConfig {
applicationId "net.julianonunes.myapp"
minSdkVersion 22
targetSdkVersion 27
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
dataBinding {
enabled = true
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation"org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.squareup.okhttp3:okhttp:3.10.0'
implementation 'com.android.support:design:27.1.1'
kapt "com.android.databinding:compiler:3.1.2"
}
Xml aktivitas saya:
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">
<data>
<variable
name="data"
type="net.julianonunes.myapp.RegisterData" />
</data>
....
</layout>
Dan inilah keluaran buildnya:

Configuration on demand is an incubating feature.
