I am trying to download and open a PDF file from a URL in Xamarin Android. I can open the URL no problem, which of course saves the PDF in the Downloads folder. Is there a way I can then access that same file and have it open automatically after being downloaded within my app? Here is how I am currently opening the URL to download:
Intent i = new Intent(Intent.ActionView); Intent browserIntent = new Intent(Intent.ActionView, Uri.Parse("http://sampleURL.com")); StartActivity(browserIntent); You would first have to know the name of the file that was download.
Then you could do this
var filename = "file.pdf"; var file = System.IO.Path.Combine(Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDownloads).ToString(), filename); var uri = Android.Net.Uri.Parse(file); Intent intent = new Intent(Intent.ActionView); intent.SetFlags(ActivityFlags.ClearTop); intent.SetDataAndType(uri, "application/pdf"); try { StartActivity(intent); } catch (ActivityNotFoundException e) { Toast.MakeText(Application.Context, "Install a pdf viewer.", ToastLength.Long).Show(); }
