This is part of my program in C#(Win): OpenFileDialog openFileDialog1 = new OpenFileDialog(); openFileDialog1.Title ="Open File"; try { if (openFileDialog1.ShowDialog() == DialogResult.OK) { string file = openFileDialog1.FileName; string fileData = File.ReadAllBytes(file); } } But in Android, the closest I can come is this: Intent intent = new Intent(Intent.ActionGetContent); intent.SetType("text/plain"); intent.AddCategory(Intent.CategoryOpenable); intent.SetAction(Intent.ActionGetContent); intent.PutExtra("android.content.extra.SHOW_ADVANCED", true); intent.PutExtra("android.content.extra.FANCY", true); intent.PutExtra("android.content.extra.SHOW_FILESIZE", true); StartActivityForResult(Intent.CreateChooser(intent, "Select file"), 0); And while I can look at the files in various folders, I cannot open any of them. Thanks. RON

Hello everyone, I am interested in learning more about edge computing and how it impacts real-time data processing. I have come across some articles that suggest edge computing enables real-time data processing and decision-making in a variety of applications. However, I am still curious about the specific ways in which edge computing achieves this.
