Android: When a content:// URI is returned for a picked file, the plugin now
tries to keep permissions to the picked content (#172, #158).
(Re-)added SourceLink support
Release version. No code changes since the version 2.1.17-beta.
Android: Fixed NullReferenceException caused by the bugfix from version 2.1.16-beta.
Android: Fixed error "Only one operation can be active at a time" when re-entering PickFile() call; now the first call returns null (#131).
Android: Fixed warning when compiling for TargetFrameworkVersion below 9.0 and using file picker from NuGet package (#125).
WPF: Fixed using NuGet package under WPF by actually compiling the FilePicker plugin for .NET 4.5 and higher (#122) (#124).
Marked IFilePicker.OpenFile() and IFilePicker.SaveFile() obsolete; the plugin focuses on picking files. Will be removed in 2.2.x.
The plugin now uses multi-targeting; no visible changes to the API, but the NuGet package explicitly lists on which platforms the plugin can be installed.
The plugin now uses SourceLink; when the Visual Studio option "Just my code" is deactivated, the user can directly debug into the plugin's code. See https://github.com/dotnet/sourcelink/
Android: When the app doesn't have Permission.ReadExternalStorage granted yet, the app will now ask the user to grant the permission (on API level >=23). The caller of PickFile() doesn't need to request permissions now. The permission is automatically added to the app when referencing this NuGet package.
WPF: Implemented FilePicker for WPF (#64).
Android: Fixed OpenFile() call with relative filename that uses wrong parent directory (#71).
Android: Fixed stack overflow when calling OpenFile() with FileData argument.
Marked FileData.ReadFully() obsolete; it shouldn't be used outside of the plugin. Will be removed in 2.1.x.
Android: Fixed getting path from OneDrive content provider (#79).
Android/iOS: File bytes are not read directly after picking, but only when FileData.DataArray is accessed or FileData.GetStream() is called; this fixes accessing large files that wouldn't fit in the device's memory, e.g. videos (#38).
Android/iOS: PickFile() now throws more exceptions when an error while picking occured; before that some error states were silently discarded.
Android: Added check if Android permission was granted; caller of PickFile() has to request permission, though.
Android: Fixed exception when trying to pick a downloaded file; the Android DownloadManager won't return an actual file path; downloaded files can only be resolved using ContentResolver (#86).
Android: fix android mime types implementation (#85)
iOS: Fixed getting pathname from FileUrl (fix of PR #54 that was reverted in PR #65).
Added support for file types across platforms (#26).
Revert pull request "Fixed Path" (#65).
Android: Fixed Path (#54); was returning File Url which cannot be used for file operations from PCL / Shared Project, instead returning path.
Fixed more NuGet package issues (#19, #23, #29).
UWP: Make UWP streamGetter use StorageFile's OpenStreamForRead method, instead of trying to use the file path and File.IO (#33).
Android: Support for content:// picked files (#22).
Android: Fixed picking files from OneDrive; the ContentProvider returns no _data column (#44).
Fixes crash in Xamarin.Forms sample when user doesn't select file; also added example code in README file (#50)
Android: Fixed picking files from the download folder; on newer devices the document ID may not be a number, but the real filename prefixed with "raw:" (#49)
Fixed NuGet package issue (#13).
The plugin was converted from using PCL to using .NET Standard, with platform support for Android, iOS and UWP platforms.
Removed Windows Phone 8 and Windows 8/8.1 support.
