Glide v3 Migration to v4 Cheatsheet

Description	V3	V4
Entry point - optional unless you have a custom GlideModule	Glide	GlideApp
Bitmap transformations	bitmapTransform()	transform()
Release bitmap	Glide.clear()	GlideApp.with(context).clear()
Custom animations	animate(android.R.anim.fade_in)	transition(GenericTransitionOptions.with(android.R.anim.fade_in))
Request builder	DrawableRequestBuilder<CustomModel>	RequestBuilder<Drawable>
Request builder	DrawableRequestBuilder<String>	RequestBuilder<Drawable>
Custom model usage	RequestManager.from(Model.class)	not needed anymore. Must be configured in GlideModule.
Custom model loaders	implements StreamModelLoader<T>	ModelLoader<Model, InputStream> (or BaseGlideUrlLoader<Model> for http/s schemes only)
Non-view targets	SimpleTarget	CustomTarget
Caching strategy	DiskCacheStrategy.SOURCE	DiskCacheStrategy.DATA
Caching strategy	DiskCacheStrategy.RESULT	DiskCacheStrategy.RESOURCE
Target specification	into<SimpleTarget<Bitmap>>(target)	into(target) no need for generic
Request listener	RequestListener<Model, GlideDrawable>	RequestListener<Drawable>
Request listener	RequestListener<String, GlideDrawable>	RequestListener<Drawable>
Drawables	GlideDrawable	Drawable
Video decoder config	videoDecoder()	frame() and do video decoder config in GlideModule registry.prepend(ParcelFileDescriptor::class.java, Bitmap::class.java, VideoDecoder.parcel(glide.bitmapPool))
Cache key	signature(new StringSignature("foo")	signature(new ObjectKey("foo"))
Loading into bitmap with fixed size	into(640, 640)	submit(640, 640)
Bitmap loading only	bitmap = Glide.with(context).load(profileImageUrl).asBitmap().into(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL).get()	bitmap = GlideApp.with(context).asBitmap().load(profileImageUrl) .submit().get()
Registering custom model loaders	glide.register(CenterCropImageInformation.class, InputStream.class, new CenterCropImageInformationLoader.Factory())	registry.append( CenterCropImageInformation::class.java, InputStream::class.java, CenterCropImageInformationLoader.Factory(context, ModelCache(500)))

Thank you.
