This is the code I use to read a pdf from the filesystem, I hope it helps!

        File file = new File("/path/to/file");          
        Uri path = Uri.fromFile(file);      
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setDataAndType(path, "application/pdf");
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        try {
             context.startActivity(intent);
            } 
         catch (ActivityNotFoundException e) {
             Toast.makeText(context, "No application available to view PDF", Toast.LENGTH_LONG).show();
            }

You can't just use file:///android_asset/button11.pdf to access file. It isn't file system path. And webview will not show your pdf even if your get file real path.

you can use pdf.js from Mozilla to display a PDF in a webview inside an Android application. Here is the solution.
