Android Samsung: how to intent samsung file explorer

I would like to get a nicer file explorer as the one which is chosen automatically by Intent. On my phone there is also the file explorer from Samsung. However it never shows up.
Here my code snippet in Kotlin
val intent = Intent(Intent.ACTION_GET_CONTENT).apply {
addCategory(Intent.CATEGORY_OPENABLE)
data = selectedUri
addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
}

val intent = Intent(Intent.ACTION_OPEN_DOCUMENT)
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("*/*");
startActivityForResult(intent, REQUEST_CODE);
For Samsung Users
val intent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
intent.putExtra("CONTENT_TYPE", "*/*");
intent.addCategory(Intent.CATEGORY_DEFAULT);

Android: make internal file picker available as a choice

When opening a file picker with the following method:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
Intent chooserIntent = Intent.createChooser(intent, "Open file");
startActivityForResult(chooserIntent, REQUEST_CODE_FILE_PICKER);
unless a default has been set, this will present the user with a choice of file pickers to use. How do you make your own, internal, file chooser available as one of the choices of file pickers presented to the user (such as the Material File Picker)?

Thanks to #CommonsWare's comment, here is the extra bit of code needed to add the internal file picker to the list of choices presented to the user:
// this bit is as before...
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
Intent chooserIntent = Intent.createChooser(intent, "Open file");
// new bit... create Intent for the internal file picker...
Intent materialFilePickerIntent = new Intent(this, FilePickerActivity.class);
materialFilePickerIntent.putExtra(FilePickerActivity.ARG_FILE_FILTER, Pattern.compile(".*\\.txt$"));
// and add the picker to the list...
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { materialFilePickerIntent });
// finally, startActivityForResult() as before...
startActivityForResult(chooserIntent, REQUEST_CODE_FILE_PICKER);

Open image for sharing

I have Android Xamarin application with imageview
OnClik I lunch intent to preview image
File file = new File(photoPath);
Intent intent = new Intent(Intent.ActionView);
intent.SetDataAndType(Uri.FromFile(file), "image/*");
intent.SetFlags(ActivityFlags.NoHistory);
StartActivity(intent);
from apps I choose 'Gallery'
when the image is opend there are no sharing options
when I open image from device 'Gallery' has sharing options
Image is saved to SD card before preview.
what am I doing wrong ?

solution that worked for me
Intent intent = new Intent();
intent.PutExtra(Intent.ActionView, photoPath);
intent.SetType("image/*");
StartActivity(Intent.CreateChooser(intent, "Select Picture"));
now I get my image opend in gallery and I can use sharing options too

Do it using Intent.ACTION_SEND and you'll get that sharing option.
Also try with Intent.ACTION_GET_CONTENT.
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), 1);

Open file manager error android

Hi there all developers:
I am using this code snippet
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(Intent.createChooser(intent, "Select File"), SELECT_FILE);`
There exists a file manager, but its giving a messege<< No apps can perform this action. Why?? Can anyone tell me?
I have also tried without Intent.ACTION_PICK

Please put my code.
it is working.
* CODE *
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivity(intent);

When I am browsing a file using intents it's not going to File Manager?

When i click on the Browse button i have added below code:
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setType("*/*");
startActivityForResult(intent, CHOOSE_FILE_REQUESTCODE);
It shows FileManager in some devices like Redmi,Asus,Micromax.But it is not showing in Samsung phones,it's not going to file manager
How to get FileManager in Samsung phones to select a file?

try this is working for me
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
startActivityForResult(intent , CHOOSE_FILE_REQUESTCODE);
for Samsung Devices
String manufactures = android.os.Build.MANUFACTURER;
if(manufactures.equalsIgnoreCase("samsung")){
Intent intent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
intent.putExtra("CONTENT_TYPE", "*/*");
startActivityForResult(intent, CHOOSE_FILE_REQUESTCODE);
}

Replace
Intent intent = new Intent(Intent.ACTION_VIEW);
as
Intent intent = new Intent(Intent.GET_CONTENT);
EDIT
#Hanuman i think that single solution that fits all models doesn't exist, all intents with "actions" have to be processed by choosers. If you use >= 4.4 devices, I recommend
Storage Access Framework
