DataT
- The type of data this loader will load (InputStream
, ParcelFileDescriptor
).public final class QMediaStoreUriLoader<DataT> extends java.lang.Object implements ModelLoader<android.net.Uri,DataT>
In particular, HEIC images on Q cannot be decoded if they've gone through Android's exif redaction, due to a bug in the implementation that corrupts the file. To avoid the issue, we need to get at the un-redacted File. There are two ways we can do so:
ContentResolver
MediaStore.setRequireOriginal will only work for applications that target Q and request and
currently have Manifest.permission.ACCESS_MEDIA_LOCATION
. It's the simplest
change to make, but it covers the fewest applications.
Querying for the file path and opening the file directly works for applications that do not target Q and for applications that do target Q but that opt in to legacy storage mode. Other options are theoretically available for applications that do not target Q, but due to other bugs, the only consistent way to get unredacted files is via the file system.
This class does not fix applications that target Q, do not opt in to legacy storage and that
don't have Manifest.permission.ACCESS_MEDIA_LOCATION
.
Avoid using this class directly, it may be removed in any future version of Glide.

ModelLoader.LoadData<DataT> |
buildLoadData(android.net.Uri uri,
int width,

Options options)
Returns a
ModelLoader.LoadData containing a DataFetcher required to decode the resource represented by this
model, as well as a set of Keys that identify the data
loaded by the DataFetcher as well as an optional list of
alternate keys from which equivalent data can be loaded. |

handles(android.net.Uri uri)
Returns true if the given model is a of a recognized type that this loader can probably load.

ModelLoader
ModelLoader.LoadData
containing a DataFetcher
required to decode the resource represented by this
model, as well as a set of Keys
that identify the data
loaded by the DataFetcher
as well as an optional list of
alternate keys from which equivalent data can be loaded. The DataFetcher
will not be
used if the resource is already cached.
Note - If no valid data fetcher can be returned (for example if a model has a null URL), then it is acceptable to return a null data fetcher from this method.

- The model representing the resource.width
- The width in pixels of the view or target the resource will be loaded into, or

ModelLoader
For example, you may want multiple Uri -> InputStream loaders. One might handle media store Uris, another might handle asset Uris, and a third might handle file Uris etc.
This method is generally expected to do no I/O and complete quickly, so best effort results
are acceptable. ModelLoaders
that return true from this method may return
null
