First, what is the difference between Glide and GlideApp? The latter seems to be automatically generated, but the steps seemed to be complicated so I used Glide instead. They both seem to have the same methods.
So, I used Glide.with(activity).load(fileName).error().into(imageView). The problem is that I cannot understand what to pass to error(). It did not take a drawable resource ID. Android Studio says the parameter is RequestBuilder< Drawable!>?, but I could not find any example.
"Error: Type mismatch: inferred type is Int but RequestBuilder< Drawable!>? was expected"
If you are using Glide v4 then you have to use RequestOptions for including the more options you want, for example centerCrop(), placeholder(), error(), priority() , diskCacheStrategy().
So after using RequestOptions your Glide would look like this-
RequestOptions options = new RequestOptions()
.centerCrop()
.placeholder(R.drawable.default_avatar)
.error(R.drawable.default_avatar)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.priority(Priority.HIGH);
Glide.with(mContext).load(imgUrl)
.apply(options)
.into(picThumbnail);
Now you can show error image and placeholder set the disk cache etc.
GlideApp is also a part of Glide v4. It is used to provide more than one Transformation in Glide v4, using the transforms() method:
GlideApp.with(mContext)
.load(imgUrl)
.transforms(new CenterCrop(), new RoundedCorners(20))
.into(target);
error() and placeholder() using GlideApp-
GlideApp.with(mContext)
.load(imageUrl)
.placeholder(R.drawable.placeholder_image)
.error(R.drawable.error_image)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.priority(Priority.HIGH)
.into(offerImage);
