Using an Intent to open a local PDF file

Question

I've searched for a while on the internet but I didnt find a solution!

In my project I put a PDF file inside the drawable folder (I dont know where else to put it, honestly). That PDF is a menù that shows the user all the food he can find in that restaurant. There is a button that enables the user to open that PDF file. By clicking over it I receive a error message. More or less it says that the App cant file my file: "Impossibile to open menuristorante.pdf".

I created a method to open that file and this is the code I wrote:

public void openMenuRistorante(View view)
{
File pdfFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/menuristorante.pdf");
Uri path = Uri.fromFile(pdfFile);
Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
pdfIntent.setDataAndType(path, "application/pdf");
pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try{
    startActivity(pdfIntent);
}catch(ActivityNotFoundException e){
    Toast.makeText(this, "Nessuna Applicazione per leggere i pdf", Toast.LENGTH_SHORT).show();
}
}

Probably I am wrong putting my file in the wrong directory.. But where have I to put it? Keep in mind that my PDF file must be already into the app, so it must be inside the phone when the user installs this App.

Thanks

Put the PDF file in the assets folder and try using the following code:

Uri file= Uri.parse("file:///android_asset/mypdf.pdf");
  String mimeType =  MimeTypeMap.getSingleton().getMimeTypeFromExtension(MimeTypeMap.getFileExtensionFromUrl(file.toString()));

try {
     Intent i;
     i = new Intent(Intent.ACTION_VIEW);
     i.setDataAndType(file,mimeType);
     startActivity(i);

} catch (ActivityNotFoundException e) {
                    Toast.makeText(this, 
                        "No Application Available to view this file type", 
                        Toast.LENGTH_SHORT).show();
                }

I'm doing a similar thing in my app, I have my files though in the download folder of my mobile in a sub-folder called "Documents", I guess you could do the same, it's better than keeping it in drawable. here's the code I use :

try {
            File file = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS + "/Documents/" + fileName);
            Intent intent = new Intent("com.adobe.reader");
            intent.setType("application/pdf");
            intent.setAction(Intent.ACTION_VIEW);
            Uri uri = Uri.fromFile(file);
            intent.setDataAndType(uri, "application/pdf");
            startActivity(intent);
        } catch (Exception e) {
            e.printStackTrace();
            Toast.makeText(Documents.this, "Erreur d'ouverture du fichier", Toast.LENGTH_LONG).show();
        }
