    emailIntent.putExtra(Intent.EXTRA_TEXT, "Text");
    emailIntent.setType("application/pdf");
    emailIntent.putExtra(Intent.EXTRA_STREAM, uri);

    startActivity(Intent.createChooser(emailIntent, "Send email using:"));

    }

public void CopyAssets() {

    try {
        files = assetManager.list("");
    } catch (IOException e) {
