Xamrin Forms: How to read the details of a file stored in device's external storage?

Question

I have implemented creating a folder and file in the device's external storage and writing data into that file using this thread.

Now I am trying to get the details of the file. For that, I have added a new function in the interface like below.

//Interface
public interface IAccessFile
{
    void CreateFile(string text);
    Java.IO.File GetFileDetails();
}

//Android implementation
public Java.IO.File GetFileDetails()
{
    string rootPath = Android.OS.Environment.ExternalStorageDirectory.AbsolutePath;
    var filePathDir = Path.Combine(rootPath, "StockPDT");
    if (File.Exists(filePathDir))
    {
        string filePath = Path.Combine(filePathDir, "STOCK.TXT");
        Java.IO.File file = new Java.IO.File(filePath);
        return file;
    }
    else
    {
        return null;
    }
}

But the problem is with the interface function part, getting below error":

The type or namespace name 'Java' could not be found (are you missing a using directive or an assembly reference?)

Screenshot:

If I return the file from the android part like above, it is easy to get the file details in the portable project. Instead of File, I try to return the file path, but it is empty. Is there any other way to get the file details other than this?

Answer 1

As per the notes in question, I tried to fetch the file details using its path.

string fileDetails = File.ReadAllText(path);
