Unsuccessful Gradle build with custom XML tag and Databinding

Question

I'm getting the build error described below when I'm trying to run a project using data binding and a custom XML tag in the bound layout:

Layout:

<data>
   <variable
        name="data"
        type="com.melontech.sff.viewmodel.DataViewModel" />
</data> 

...

<ImageView 
   android:id="@+id/image"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:src="@mipmap/placeholder_img"
   app:imageUrl="@{data.imageUrl}" />

...

View Model has the following Binding adapter:

@BindingAdapter("bind:imageUrl")
public static void getImageUrl(ImageView imageView, String url) {
    Timber.d("LOAD IMAGE WITH URL %s", url);
}

The code that creates the ViewHolder and makes the binding is the following one:

@Override
public ModelViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    ModelListItemBinding binding = DataBindingUtil.inflate(LayoutInflater.from(parent.getContext()), R.layout.model_list_item, parent, false);
    return new ModelViewHolder(binding);
}

The build error:

Error:Execution failed for task ':app:transformJackWithJackForDebug'.

Data binding is enabled in the Gradle file.

If I move the this feature in a separate clean project and bind data like this:

ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main);

Custom XML attributes work like expected and build is successful.

Do you have any ideas what could be the reason for the build error?

Answer 1

Jd Prajapati here is my ViewModel class:

public class DataViewModel {

   private Data data;

   public DataViewModel() {
   }

   public DataViewModel(Data data) {
       this.data = data;
   }

   public Data getData() {
       return data;
   }

   public void setData(Data data) {
       this.data = data;
   }

   public String getTitle() {
       if (data != null) {
           if (!TextUtils.isEmpty(data.getTitle())) {
               return data.getTitle();
           }
       }
       //Case when title doesn't exist
       return "";
   }

   public String getImageUrl() {
       if (data != null) {
           if (!TextUtils.isEmpty(data.getMainPic())) {
               return data.getMainPic();
           }
       }
       //Case when poster url doesn't exist
       return "";
   }

   @BindingAdapter("imageUrl")
   public static void getImageUrl(ImageView imageView, String url) {
        Timber.d("LOAD IMAGE WITH URL %s", url);
   }
}

BTW I've found a way to make the Gradle build the project by changing the ImageView property to the following:

<ImageView
   android:id="@+id/movie_poster"
   android:layout_width="@dimen/dim_160dp"
   android:layout_height="@dimen/dim_240dp"
   android:src="@mipmap/movie_placeholder_img"
   app:imageUrl="@{singleMovie.getImageUrl()}" />
