how to create a pdf

[David]

Good afternoon, I am following the steps to create a pdf of these links:

https://www.syncfusion.com/kb/9174/how-to-create-a-pdf-file-in-xamarin

https://help.syncfusion.com/file-formats/pdf/create-pdf-file-in-xamarin

Even in the example project they give, I get the same problem, when pressing the button nothing happens and I see that the method is exited when it passes through the following line:

using System;

using System.IO;

using Android.Content;

using Java.IO;

using Xamarin.Forms;

using System.Threading.Tasks;

[assembly: Dependency(typeof(SaveAndroid))]

class SaveAndroid: ISave

    {

        //Method to save document as a file in Android and view the saved document

        public async Task SaveAndView(string fileName, String contentType, MemoryStream stream)

        {

            string root = null;

            //Get the root path in android device.

            if (Android.OS.Environment.IsExternalStorageEmulated)

            {

                root = Android.OS.Environment.ExternalStorageDirectory.ToString();

            }

            else

                root = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

            //Create directory and file 

            Java.IO.File myDir = new Java.IO.File(root + "/Syncfusion");

            myDir.Mkdir();

            Java.IO.File file = new Java.IO.File(myDir, fileName);

            //Remove if the file exists

            if (file.Exists()) file.Delete();

            //Write the stream into the file

            FileOutputStream outs = new FileOutputStream(file); //AQUI

            outs.Write(stream.ToArray());

            outs.Flush();

            outs.Close();

            //Invoke the created file for viewing

            if (file.Exists())

            {

                Android.Net.Uri path = Android.Net.Uri.FromFile(file);

                string extension = Android.Webkit.MimeTypeMap.GetFileExtensionFromUrl(Android.Net.Uri.FromFile(file).ToString());

                string mimeType = Android.Webkit.MimeTypeMap.Singleton.GetMimeTypeFromExtension(extension);

                Intent intent = new Intent(Intent.ActionView);

                intent.SetDataAndType(path, mimeType);

                Forms.Context.StartActivity(Intent.CreateChooser(intent, "Choose App"));

            }

        }

    }

I have already granted you the read and write permissions:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I have also encountered this problem.

I have handled it successfully.

Because I am missing the folder xml/provider_paths

And I modified this code.

Luckily it ran successfully

<application android:label="Demo.Android" android:icon="@drawable/icon">

    <provider android:name="android.support.v4.content.FileProvider"

        android:authorities="${applicationId}.provider"

        android:exported="false"

        android:grantUriPermissions="true">

      <meta-data android:name="android.support.FILE_PROVIDER_PATHS"

                 android:resource="@xml/provider_paths" />

    </provider>

  </application>
