Android studio Action call to run USSD codes

Question

By using an app I want to run a USSD code, but the problem is it doesn't recognize the "#" symbol. If I want to run "*100#" it recognize the input only as "*100". How to add the "#". and what is the reason to not recognize that?

Here is my code ...

  checkBalance.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent i = new Intent(Intent.ACTION_CALL);


            i.setData(Uri.parse("tel:"+"*100#"));

            if (ActivityCompat.checkSelfPermission(mobitelPage.this,
                    Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                return;
            }
            startActivity(i);



        }
    });

Try this code.Use Uri.encode("#"):

    String encodedHash = Uri.encode("#");
    i.setData(Uri.parse("tel:"+"*100"+encodedHash));

    if (ActivityCompat.checkSelfPermission(this,
            Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
        return;
    }
    startActivity(i);
