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.

Here is the solution. https://stackoverflow.com/a/10981194/1635488

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