Generate PDF file and attach to e-mail

Question

first post here.

I have read all similar posts without finding any answer, i'm a newbie at dev in general.

Here is what i'm looking for:

On button click, the code generates a PDF with some info, and i just want to send the created pdf by mail. First problem is when i choose an email app to send the mail, i got a message "Impossible to attach file". Second problem is that the created file is not readable on the phone while it's readable on PC.

By searching i found out that it may be in relation with permission. I tried setReadablemethod without result. Android studio makes a hint (result of setReadable is ignored).

Code :

public class VerifList extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_verif_list);

        //Variables

        //Strings
        final String name;
        final String myFormat;




        //Others

        final SimpleDateFormat sdf;
        final String datePdf;

        //Buttons

Try the below code in your Activity..

package com.example.pdfshare;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;

import android.app.Activity;
import android.content.Intent;
import android.content.FileProvider;
import android.graphics.pdf.PdfDocument;
import android.graphics.pdf.PdfDocument.Page;
import android.graphics.pdf.PdfDocument.PageInfo;
import android.net.Uri;
import android.os.Bundle;
import android.print.PrintAttributes;
import android.print.PrintAttributes.Margins;
import android.print.PrintAttributes.Resolution;
import android.print.pdf.PrintedPdfDocument;
import android.view.Menu;
import android.view.View;


public class MainActivity extends Activity implements Runnable {

private Intent mShareIntent;

private OutputStream os;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

/** PDF Gen should run in own thread to not slow the GUI */
public void makeAndSharePDF(View buttonSource) {
    new Thread(this).start();
}   

public void run() {

    // Create a shiny new (but blank) PDF document in memory
    // We want it to optionally be printable, so add PrintAttributes
    // and use a PrintedPdfDocument. Simpler: new PdfDocument().
    PrintAttributes printAttrs = new PrintAttributes.Builder().
            setColorMode(PrintAttributes.COLOR_MODE_COLOR).
            setMediaSize(PrintAttributes.MediaSize.NA_LETTER).
            setResolution(new Resolution("zooey", PRINT_SERVICE, 300, 300)).
            setMinMargins(Margins.NO_MARGINS).
            build();
    PdfDocument document = new PrintedPdfDocument(this, printAttrs);

    // crate a page description
    PageInfo pageInfo = new PageInfo.Builder(300, 300, 1).create();

    // create a new page from the PageInfo
    Page page = document.startPage(pageInfo);

    // repaint the user's text into the page
    View content = findViewById(R.id.textArea);
    content.draw(page.getCanvas());

    // do final processing of the page
    document.finishPage(page);

    // Here you could add more pages in a longer doc app, but you'd have
    // to handle page-breaking yourself in e.g., write your own word processor...

    // Now write the PDF document to a file; it actually needs to be a file
    // since the Share mechanism can't accept a byte[]. though it can
    // accept a String/CharSequence. Meh.
    try {
        File pdfDirPath = new File(getFilesDir(), "pdfs");
        pdfDirPath.mkdirs();
        File file = new File(pdfDirPath, "pdfsend.pdf");
        Uri contentUri = FileProvider.getUriForFile(this, "com.example.fileprovider", file);
        os = new FileOutputStream(file);
        document.writeTo(os);
        document.close();
        os.close();

        shareDocument(contentUri);
    } catch (IOException e) {
        throw new RuntimeException("Error generating file", e);
    }
}

private void shareDocument(Uri uri) {
    mShareIntent = new Intent();
    mShareIntent.setAction(Intent.ACTION_SEND);
    mShareIntent.setType("application/pdf");
    // Assuming it may go via eMail:
    mShareIntent.putExtra(Intent.EXTRA_SUBJECT, "Here is a PDF from PdfSend");
    // Attach the PDf as a Uri, since Android can't take it as bytes yet.
    mShareIntent.putExtra(Intent.EXTRA_STREAM, uri);
    startActivity(mShareIntent);
    return;
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
}

The above code is self explanatory with comments.. All the Best..

Thank you very much! worked fine! One another question : where the file is stocked at? is it accessible? Thx — ezek, Mar 22 '20 at 16:42
