Wrong extension detection in FileUtil.getImageExtension(). OneDrive can't be used.

[Andrew0000]

Summary

In case of gallery picking from cloud providers like GoogleDrive and OneDrive, FileUtil.getImageExtension() function detects wrong extensions. And it leads to an error in file creation in FileUtil.getImageFile(fileDir = mFileDir, extension = extension) in case of OneDrive (+ probably wrong file creation in case of GoogleDrive).
It detects always jpg for GoogleDrive and something like com/Item/RID/C8BD%21119/Property/?RefreshOption=AutoRefresh&RefreshTimeOut=15000&CostAttributionKey=11-21-1 for OneDrive.

Example of uri from OneDrive (modified a bit for security reason):
content://com.microsoft.skydrive.content.StorageAccessProvider/document/content%3A%2F%2Fcom.microsoft.skydrive.content.metadata%2FDrive%2FRID%acc_name%2FItem%2FRID%2FC8%3FRefreshOption%3DAutoRefresh%26RefreshTimeOut%3D15000%26CostAttributionKey%3D11-21-1

Example of uri from GoogleDrive (modified a bit for security reason):
content://com.google.android.apps.docs.storage/document/acc%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D

From the user perspective it leads to a toast: Failed to crop image and impossibility to pick an image from OneDrive.

Code to reproduce

Common code, nothing special.

Android version

I suppose it can be fixed in the following ways:
a)
If uri has a content:// scheme - then FileUtil.getImageExtension() should use another extension detection algorithm

val mime = contentResolver.getType(uri)
val ext = MimeTypeMap.getSingleton().getExtensionFromMimeType(mime)

b)
Or maybe MediaStore.Images.Media.DISPLAY_NAME can be used.

Note: I haven't tested these approaches.

FYI: I made my own library, it works there: https://github.com/Andrew0000/ImagePickerPlus
