    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)))
