android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@3decac7 -- permission denied for this window type

I have an windows manager inside the broadcast receiver and am using API > 23 so i provided overlay permission in the main activity like below. 

 if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        Intent myIntent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
        startActivity(myIntent);
    }

After providing the permission also am getting the below error .

 android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@3decac7 -- permission denied for this window type.

window manager used in the broadcast receiver 

 WindowManager.LayoutParams params = new 
 WindowManager.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT,
                            WindowManager.LayoutParams.MATCH_PARENT,
                            WindowManager.LayoutParams.TYPE_SYSTEM_DIALOG,
                            WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED |

                    params.gravity= Gravity.CENTER;
                    params.x=0;

You have a bad layout type ( WindowManager.LayoutParams.TYPE_SYSTEM_DIALOG). You can use TYPE_APPLICATION_OVERLAY for api >= 26 and TYPE_TOAST for lower api. Also you can read the WindowManager.LayoutParams api doc to know wich type you can use
