1. check if installed Cyano APP :

 public static boolean checkInstallCynoApp(Context context) {
        final PackageManager packageManager = context.getPackageManager();// get packagemanager
        List<PackageInfo> pinfo = packageManager.getInstalledPackages(0);// get info 
        if (pinfo != null) {
            for (int i = 0; i < pinfo.size(); i++) {
                String pn = pinfo.get(i).packageName.toLowerCase(Locale.ENGLISH);
                if (pn.equals("com.github.ont.cyanowallet")) {
                    return true;
                }
            }

    String sendData = Base64.encodeToString(Uri.encode(data).getBytes(), Base64.NO_WRAP);
    Intent intent = new Intent("android.intent.action.VIEW");
    intent.setData(Uri.parse("ontprovider://ont.io?param=" + sendData ));
    intent.addCategory("android.intent.category.DEFAULT");
    startActivity(intent);

    String sendData = Base64.encodeToString(Uri.encode(data).getBytes(), Base64.NO_WRAP);
    Intent intent = new Intent("android.intent.action.VIEW");
    intent.setData(Uri.parse("ontprovider://ont.io?param=" + sendData ));
