Unable To Create Pdf In Android 11(r)

Greetings to community I am generating PDF reports using ITEXT library. 'com.itextpdf:itextpdf:5.0.6' I am doing this like that Document document = new Document(); fileNam

Solution 1:

Solution to create and display PDF in Android 11

Create @xml/provide_paths.xml in resource directory

<?xml version="1.0" encoding="utf-8"?><pathsxmlns:android="http://schemas.android.com/apk/res/android"><external-pathname="external_files"path="." /><root-pathname="external_files"path="/storage/" /></paths>

Add this is Manifest.xml application tag

     <application
<--other properties-->
            android:requestLegacyExternalStorage="true"android:usesCleartextTraffic="true">

     <providerandroid:name="androidx.core.content.FileProvider"android:authorities="${applicationId}.provider"android:exported="false"android:grantUriPermissions="true"><meta-dataandroid:name="android.support.FILE_PROVIDER_PATHS"android:resource="@xml/provider_paths" /></provider>

Now create and display PDF

StringfileName1="";
Documentdocument=newDocument();
    // Location to save
    fileName1 = "TEST" + ".pdf";
    Stringdest= context.getExternalFilesDir(null) + "/";

    Filedir=newFile(dest);
    if (!dir.exists())
        dir.mkdirs();


    try {
        Filefile=newFile(dest, fileName);
        file.createNewFile();
        FileOutputStreamfOut=newFileOutputStream(file, false);
        PdfWriter.getInstance(document, fOut);
    } catch (DocumentException e) {
        e.printStackTrace();
        Log.v("PdfError", e.toString());
    } catch (FileNotFoundException e) {
        e.printStackTrace();
        Log.v("PdfError", e.toString());


    } catch (IOException e) {
        e.printStackTrace();
    }

    // Open to write
        document.open();
        document.add(newParagraph(""));
        document.add(newChunk(""));
    } catch (DocumentException e) {
        e.printStackTrace();
    }


      document.close();

    FilepdfFile=newFile(dest+"/"+fileName1);
    if (!pdfFile.exists()) {
        pdfFile.mkdir();
    }



    if (pdfFile != null && pdfFile.exists() ) //Checking for the file is exist or not
    {
        
        Intentintent=newIntent(Intent.ACTION_VIEW);


        UrimURI= FileProvider.getUriForFile(
                context,
                context.getApplicationContext()
                        .getPackageName() + ".provider", pdfFile);
        intent.setDataAndType(mURI, "application/pdf");
        intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_GRANT_READ_URI_PERMISSION);

        try {
            context.startActivity(intent);
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    } else {

        Toast.makeText(context, "The file not exists! ", Toast.LENGTH_SHORT).show();

    }

This is how you can make PDF through iText library and can display it.
