open failed: ENOENT (No such file or directory) exception while creating pdf

[Reihaneh Khaksaran]

Hi,

I am trying to create a pdf from my XAML, and followed the exact same instructions in the following link:

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

but problem is that it doesn't create anything,! tried to debug the code and realized that in SaveAndroid class on the line  'FileOutputStream outs = new FileOutputStream(file);' it throws an exception, and here is the message: "/storage/emulated/0/Syncfusion/Output.pdf: open failed: ENOENT (No such file or directory)"

so, can you please help me with this issue?

I also had the same issue when I tried to run this sample:

Thanks in advance

Hi Reihaneh, 

Thank you for contacting Syncfusion support. 

The ENOENT (No such file or directory) error may occur in application, If the application do not have storage permission. We suggest you to ensure whether the application has storage permission to read and write file in storage location. We have modified sample to provide storage permission at run time. Please find the sample below for your reference. 

Sample link: http://www.syncfusion.com/downloads/support/forum/140979/ze/PdfTableCreation838435527 

Kindly refer below Xamarin link to provide permission for android application.

Please let us know if you need further assistance in this.

Hi Reihaneh, 

The PDF file is saved in android platform using SaveTextAsync method from SaveAndroid class and it is included in Android project. In the SaveTextAsync method we are creating folder name with Syncfusion and inside the folder the PDF file is created.  You can find the output PDF file “/storage/emulated/0/Syncfusion/Output.pdf” in this location. 

 

Please let us know if you need further assistance on this.

Karthikeyan

The sample works because it uses a old Xamarin Forms Version, using XF 5, the exception is throwed.

Another comment, the exception is throwed using Android target version to 11, if you set it to 10 or 9, it works fine.

Hi Christian, 

 

Thank you for contacting Syncfusion support.

 

We have created a sample to write the PDF document in Android 11 and attached it for your reference. Kindly try this sample on your end and let us know whether it works or not.  

  

In this sample we have modified the following  

  

1. Enabled the androidLegacyExtranalStorage in the AndroidManifest.xml file.

            <application android:label=" PDFXamarinSample.Android" android:requestLegacyExternalStorage="true">  

  

  

2. User permission for read, write external storage.

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

</uses-permission>  

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

  

3. Replaced the following code to get the external storage download folder in the SaveAndroid.cs file.

if (Android.OS.Environment.IsExternalStorageEmulated)  

  {  

root = Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDownloads).AbsolutePath;              

  }

This article needs updated to include Karthikeyan and Gowthamraj's fixes. It does not work for Xamarin.Forms 5.0.0.2196 and Android 11 without their suggestions. FileProvider, though mentioned in the article, also isn't shown in the code samples.

We will consider your request to update the documentation. We will let you know once the KB documentation got published with the requested changes.
