I'm not able to setup Android Data Binding

Question

I have this in my root build.gradle file:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
    }
}

and in the app build.gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.company.app"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    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-v7:22.2.0'
    //more third-party libraries
}

And this is my layout:

<layout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools">

    <data>

        <variable
            name="user"
            type="com.company.app.models.LoginCredentials"/>
    </data>

    <EditText
        android:layout_width="match_parent"
        android:layout_height="55dp"
        android:text="@{user.username}"/>

    <!-- More layouts and widgets -->
</layout>

But I get this error:

Error:(82, 35) No resource type specified (at 'text' with value '@{user.username}').

I have tried to put:

dataBinding { 
    enabled = true 
}

but I get this another error:

Error:Could not find com.android.databinding:library:1.0-rc3.

How can I do? I have just updated Android Studio to v1.5.1.

At first set compileSdkVersion 23 buildToolsVersion "23.0.1" & targetSdkVersion 23 & compile 'com.android.support:appcompat-v7:23.1.0' — IntelliJ Amiya

And don't forget dataBinding{ enabled = true }in the android { } section. — yennsarah

At least it works!! Thanks! I have put dataBinding.enabled = true and updated version to 23 — Héctor Valls

Actually compileSdkVersion 21 creating problem . You need to use UPGRADED Version .

You should use

compileSdkVersion 23 
buildToolsVersion "23.0.1"

&

targetSdkVersion 23

You need to include dataBinding.enabled = true

Add classpath "com.android.databinding:dataBinder:1.0-rc1" to your build.gradle like this

buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:1.5.0' classpath "com.android.databinding:dataBinder:1.0-rc1" } }

Change your build.gradle on putting what as mentioned in the previous comments of @IntelliJAmiya and adding apply plugin: 'com.android.databinding' Your gradle will be like

apply plugin: 'com.android.application'
apply plugin: 'com.android.databinding'  
 android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"


  defaultConfig {
        applicationId "com.company.app"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),   'proguard-rules.pro'
        }
    }
}
 dataBinding { 
        enabled = true 
    }
    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        testCompile 'junit:junit:4.12'
        compile 'com.android.support:appcompat-v7:23.1.0'
        //more third-party libraries
    }

Thanks for your answer. Actually, com.android.databinding:dataBinder:1.0-rc1 is not needed to be declared explicitly. It is included in classpath 'com.android.tools.build:gradle:1.5.0'.
