Android sharing Files, by sending them via email or other apps

this is the code for sharing file in android

Intent intentShareFile = new Intent(Intent.ACTION_SEND);
File fileWithinMyDir = new File(myFilePath);

if(fileWithinMyDir.exists()) {
    intentShareFile.setType("application/pdf");
    intentShareFile.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+myFilePath));

    intentShareFile.putExtra(Intent.EXTRA_SUBJECT,
                        "Sharing File...");
    intentShareFile.putExtra(Intent.EXTRA_TEXT, "Sharing File...");

    startActivity(Intent.createChooser(intentShareFile, "Share File"));
}

Below is another method to share PDF file if you have put file provider in manifest

Uri pdfUri;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        pdfUri = FileProvider.getUriForFile(PDFViewerActivity.this, fileprovider, pdfFile);
} else {
        pdfUri = Uri.fromFile(pdfFile);
}
Intent share = new Intent();
share.setAction(Intent.ACTION_SEND);
share.setType("application/pdf");
share.putExtra(Intent.EXTRA_STREAM, pdfUri);
startActivity(Intent.createChooser(share, "Share file"));
