You cannot open the pdf file directly from the assets folder.You first have to write the file to sd card from assets folder and then read it from sd card.

Try out the below code to copy and read the file from assets folder:

 //method to write the PDFs file to sd card 
 private void PDFFileCopyandReadAssets()
    {
        AssetManager assetManager = getAssets();

        InputStream in = null;
        OutputStream out = null;
        File file = new File(getFilesDir(), "test.pdf");
        try
        {
            in = assetManager.open("test.pdf");
            out = openFileOutput(file.getName(), Context.MODE_WORLD_READABLE);

            readFile(in, out);
            in.close();
            in = null;
            out.flush();
            out.close();
            out = null;
        } catch (Exception e)
        {
            Log.e("tag", e.getMessage());
        }

        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setDataAndType(
                Uri.parse("file://" + getFilesDir() + "/test.pdf"),
                "application/pdf");

        startActivity(intent);
    }

    private void readFile(InputStream in, OutputStream out) throws IOException
    {
        byte[] buffer = new byte[1024];
        int read;
        while ((read = in.read(buffer)) != -1)
        {
            out.write(buffer, 0, read);
        }
    }

Open the file from sdcard as below:

File file = new File("/sdcard/test.pdf");        
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file),"application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

Also provide a permission to write into your external storage in your manifest.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
