Build error as soon as I enable dataBinding for Android Library Project

I am getting a build error as soon as I enable dataBinding for my library project:

AAPT: No resource type specified (at 'text' with value '@{user.name}')

If I enable dataBinding for the application module, it works fine. But if I enable dataBinding for my lib project, I get the above error.

build.gradle of application module

apply plugin: 'com.android.application'

android {
   compileSdkVersion 23
   buildToolsVersion "23.0.2"

dataBinding{
    enabled true
}
defaultConfig {
    applicationId "xyz.databindingtrial"
    minSdkVersion 19
    targetSdkVersion 23
    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-v7:23.3.0'
  compile project(path: ':librarytrial')
}

build.gradle of lib project

apply plugin: 'com.android.library'

android {
  compileSdkVersion 23
  buildToolsVersion "23.0.2"

dataBinding{
    enabled true
}

defaultConfig {
    minSdkVersion 19
    targetSdkVersion 23
    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-v7:23.3.0'
}

The layout file:

<data class="UserTrackingBinding">

    <variable
        name="user"
        type="xyz.databindingtrial.model.User"/>
</data>

<RelativeLayout
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="xyz.databindingtrial.MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@{user.name}"/>
</RelativeLayout>

The activity code

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  UserTrackingBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
  User user = new User("Test");
  binding.setUser(user);

}

User Model

public class User extends BaseObservable {
 private final String name;
 public User(String name){
 this.name = name;
 }
 @Bindable
 public String getName() {
  return name;
 }
}

Does dataBinding not work with library projects? If it does, what is wrong with my setup?

Thanks

Figured out the issue. The package structure messed up things for me. The package structure in the manifest and the actual package structure was different. Reason being we are dealing with legacy codebase and it got overlooked. It is working fine.

It does work with library projects but any app that depends on a library that uses data binding has to enable data binding even if they don't use it.
