从MediaStore API获得真正的道路
我正在为我的应用构建一个内置文件管理器，并且正在使用MediaStore查询文件。
我得到了一切，除了我回来的URI并不是要滑行的喜欢。
类Java.io.filenotfoundexception：/external/images/媒体/37：打开失败：enoent（无此类文件或目录）
我理解当前的问题是没有添加协议，因此Glide不知道如何读取它，但是我不知道如何添加协议，我的印象是，使用contenturis.withappendedId会为我处理这一点，但似乎并非如此。
val mediaList = mutableListOf<Uri>()
val query = buildQuery(folderId, onlyImages)
query?.use { cursor ->
val columnIndexId = cursor.getColumnIndexOrThrow(MediaStore.Files.FileColumns._ID)
val columnIndexMimeType = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.MIME_TYPE)
val columnIndexDuration = cursor.getColumnIndexOrThrow(MediaStore.Video.VideoColumns.DURATION)
while (cursor.moveToNext())
{
val id = cursor.getLong(columnIndexId)
val contentUri = ContentUris.withAppendedId(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, id)
mediaList.add(contentUri)
}
}
return mediaList
我正试图使用数据丢失，因为我已经知道这已经折旧，我只需要与Android 8+一起使用此解决方案。
I'm building a built-in file manager for my app and I'm using MediaStore to query for the files.
I got everything working, except that the URI I get back is not to Glide's liking.
class java.io.FileNotFoundException: /external/images/media/37: open failed: ENOENT (No such file or directory)
I understand the issue at hand is that there's no protocol added so glide doesn't know how to read it, but I don't know how to add the protocol, I was under the impression that using ContentUris.withAppendedId would handle that for me but it appears to not be.
val mediaList = mutableListOf<Uri>()
val query = buildQuery(folderId, onlyImages)
query?.use { cursor ->
val columnIndexId = cursor.getColumnIndexOrThrow(MediaStore.Files.FileColumns._ID)
val columnIndexMimeType = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.MIME_TYPE)
val columnIndexDuration = cursor.getColumnIndexOrThrow(MediaStore.Video.VideoColumns.DURATION)
while (cursor.moveToNext())
{
val id = cursor.getLong(columnIndexId)
val contentUri = ContentUris.withAppendedId(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, id)
mediaList.add(contentUri)
}
}
return mediaList
I'm trying to void using DATA as I already know that's depreciated and I just need this solution work with Android 8+.

您是将
contenturi转换为路径吗？你不应该这样做。您的contenturi应该看起来像在下面一样，然后Glide将接受它：Are you converting the
contentUrito a path? You shouldn't be doing that. YourcontentUrishould look like it does below, and then Glide will accept it:
