I am trying to load a custom model into Glide but getting this error:
GlideExecutor: Request threw uncaught throwable com.bumptech.glide.Registry$NoModelLoaderAvailableException: Failed to find any ModelLoaders for model: com.company.project.glide.Movie@aac331a
Glide Version: 4.0.0
My codes:
Model
public class Movie { private String name; private String artist; public Movie(String name, String artist) { this.name = name; this.artist = artist; } public String getName() { return name; } public String getArtist() { return artist; } } Module
@com.bumptech.glide.annotation.GlideModule public class GlideModule extends AppGlideModule { @Override public boolean isManifestParsingEnabled() { return false; } @Override public void applyOptions(Context context, GlideBuilder builder) { super.applyOptions(context, builder); } @Override public void registerComponents(Context context, Registry registry) { registry.append(Movie.class, InputStream.class, new MovieArtModel.Factory()); } } ModelLoader
public class MovieArtModel implements ModelLoader<Movie, InputStream> { @Nullable @Override public LoadData<InputStream> buildLoadData(Movie movie, int width, int height, Options options) { Timber.d("buildLoadData: "); return new LoadData<>(new ObjectKey(movie), new MovieArtLoader(movie, width, height)); } @Override public boolean handles(Movie movie) { return false; } public static class Factory implements ModelLoaderFactory<Movie, InputStream> { @Override public ModelLoader<Movie, InputStream> build(MultiModelLoaderFactory multiFactory) { return new MovieArtModel(); } @Override public void teardown() { } } static class MovieArtLoader implements DataFetcher<InputStream> { private Movie movie; private boolean isCancelled = false; private int widthSize; private int heightSize; MovieArtLoader(Movie movie, int widthSize, int heightSize) { Timber.d("MovieArtLoader: Initializing...width size = " + widthSize + " :: heightSize = " + heightSize); this.movie = movie; this.widthSize = widthSize; this.heightSize = heightSize; } @Override public void loadData(Priority priority, DataCallback<? super InputStream> callback) { Timber.d("loadData"); //First check if request is not cancelled before starting request if(!isCancelled()) { InputStream inputStream = getMovieArtInputStream(movie); if (inputStream != null) { callback.onDataReady(inputStream); } else { callback.onLoadFailed(new IOException("Forced Glide network failure. Can't load Movie image")); } } } return null; } @Override public void cleanup() { Timber.d("cleanup: "); } @Override public void cancel() { Timber.d("cancel: "); isCancelled = true; } @Override public Class<InputStream> getDataClass() { return null; } @Override public DataSource getDataSource() { return null; } private boolean isCancelled() { return isCancelled; } } Then I am loading it thus:
GlideApp.with(itemView.getContext()) .asBitmap() .load(new Movie(book.getMovieName(), book.getArtist())) .placeholder(R.drawable.movie_default_small) .diskCacheStrategy(DiskCacheStrategy.RESOURCE) .listener(this) .into(imageView); Please where am I getting it wrong?
EDIT
I applied the answer below but I began to get NPE. This is the stacktrace:

NoModelLoaderAvailableException happened when no {@linkcom.bumptech.glide.load.model.ModelLoader} is registered for a given model class, and that fixed with @talkLittle answer, and plus on that Movie should implement equals() and hashCode() to get caching to work correctly.
The new NPE happened because you accepted @Nullable would try @NonNull annotation.

@Override public boolean handles(Movie movie) { return true; } You need to do this or else Glide will ignore your ModelLoader, thinking it does not handle the provided Movie model.
