title: how to remove "call requires permission which may.." error in Android Studio
body: <p>My code </p>
  
  <pre><code>private void continueCall() {
          Intent callIntent = new Intent(Intent.ACTION_CALL);
          callIntent.setData(Uri.parse("tel:" + phoneNoToCall));
          startActivity(callIntent);
  }
  </code></pre>
  
  <p>Above requires whether user grant permission <code>CALL_PHONE</code> at run time which I have checked as </p>
  
  <pre><code>private void call() {
      if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
          continueCall();
      } else {
          requestCallPermission();
      }
  }
  </code></pre>
  
  <p>Still Android studio showing error <strong>"call requires permission which may..."</strong></p>
  
  <p>How to remove this error? Or at least suppress it.</p>
