title: Android studio Action call to run USSD codes
body: <p>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?</p>
  
  <p>Here is my code ...</p>
  
  <pre><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);
  
  
  
          }
      });
  </code></pre>
