I am new in android and working on one android project in which I have to display a chosen pdf from the device either from internal storage(Priority) or from external Storage. I am enclosing the used code below.
private void openLocalPDF(File pdffile) {
File file = new File(Environment.getExternalStorageDirectory(), pdffile.getName());
Uri path = PdfFileProvider.getUriForFile(activity.getApplicationContext(), BuildConfig.APPLICATION_ID + ".provider", file);
Intent target = new Intent(Intent.ACTION_VIEW);
target.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
target.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
target.setDataAndType(path, "application/pdf");
Intent intent = Intent.createChooser(target, "Open File");
try {
activity.startActivity(intent);
} catch (ActivityNotFoundException e) {
Toast.makeText(getActivity(), "Please install some pdf viewer app", Toast.LENGTH_LONG).show();
}
