Try to rename the uri from file:///android_assets/ to file:///android_asset/

The correct path for files stored in assets folder is file:///android_asset/xxx with no "s"

For example:

Intent intent = new Intent(Intent.ACTION_VIEW);  
intent.addFlags (Intent.FLAG_ACTIVITY_NEW_TASK);  
Uri uri = Uri.fromFile(new File("file:///android_asset/abc.pdf"));  
intent.setDataAndType (uri, "application/pdf");  
this.startActivity(intent);

try this

 public class SampleActivity extends Activity
        {

            @Override
            protected void onCreate(Bundle savedInstanceState)
            {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.main);
                CopyReadAssets();

            }

            private void CopyReadAssets()
            {
                AssetManager assetManager = getAssets();

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

                    copyFile(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() + "/abc.pdf"),
                        "application/pdf");

                startActivity(intent);
            }

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

        }
