Failed to Generate Data Binding (FGDB)

I am using data binding in my project, and when using  <layout> and  <data> in the data binding xml class, unfortunately it doesn't work properly.. no files are generated at all. For example I have activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <data>    </data>
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </RelativeLayout>
</layout>

Now if I write  ActivityMainBinding in  my activity/fragment  it shows error that class is not available. But after including  <variable> in my xml file it is able to generate ActivityMainBinding class.

Is there something wrong with my project configuration?

Android Studio : 2.1.3
Classpath : com.android.tools.build:gradle:2.1.3
minSdkVersion 16
targetSdkVersion 24
buildToolsVersion 24.0.0

Solution

I didn't get a satisfactory answer. These are the tips which are a summary of my knowledge about data binding.

Tips to solve data binding related issues, it is better if you update Android Studio and Gradle plugin version to the latest. Because I did not face much issue after AS 3.2 version.

1. Make sure the data-binding configuration is enabled

You must enable data binding in your build.gradle file. If not, add this and Sync.

android {
    ...
    buildFeatures {
        dataBinding true
    }
}

2. Clean up your project

Clean your project with the clean up project & clear cache menu, then rebuild it again and enjoy working with auto suggestions for calling XML assets via data binding.
