I have a pdf file containing an audio sound button. I need the audio to run when I click this button without opening other apps.

pdfView = (PDFView) findViewById(R.id.pdfView);
pdfView.fromFile(new File("/storage/sdcard0/Download/pdf.pdf")).defaultPage(1).enableSwipe(true).onPageChange(this).load();
