WindowManager $ BadTokenException: cannot add window android.view.ViewRootImpl$W@61b864 - permission is allowed for window type 2010

I am trying to create a System Overlay window that will also be displayed on the lockscreen. I managed to do this on version 6.0, but it does not work on versions 7.0 and 8.0. First, I was switched to Overlay setting for my application (as expected from Android M and beyond), and I enabled it. But now it continues to crash when I tried to start the service from the application. I tried everything related to this problem, but nothing helps me solve it yet. I get this error every time I try to start the service: -

Here is my code :-( MyService.java)

@Override
public void onCreate() {
    super.onCreate();
            HeadView = LayoutInflater.from(this).inflate(R.layout.overlay_head,null);
    final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
            WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
            PixelFormat.TRANSLUCENT);
    params.gravity = Gravity.TOP | Gravity.LEFT;
    params.x = 0;
    params.y = 100;
    mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
    mWindowManager.addView(HeadView, params);  //I’m getting error here...(MyService.java:64)from error log

    ImageView closeButton = (ImageView) HeadView.findViewById(R.id.close_btn);
    closeButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            stopSelf();
        }
    });

    final ImageView chatHeadImage = (ImageView) HeadView.findViewById(R.id.head);
    chatHeadImage.setOnTouchListener(new View.OnTouchListener() {
//Code for OnTouch.
        }
    });
}

My MainActivity, where I call the above service: - (MyActivity.java)

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    back=(Button) findViewById(R.id.jump);
final Intent intentService=new Intent(MainActivity.this, MyService.class);
    if (Build.VERSION.SDK_INT >= 23 && !Settings.canDrawOverlays(MainActivity.this)) {

        //If the draw over permission is not available open the settings screen
        //to grant the permission.
        Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
                Uri.parse("package:" + getPackageName()));
        startActivityForResult(intent,1234);
    }else {
        back.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                startService(intentService);
                finish();
            }
        });
    }

}

 @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     if (requestCode == 1234) {

         //Check if the permission is granted or not.
         if (Build.VERSION.SDK_INT >= 23 && Settings.canDrawOverlays(MainActivity.this)) {
             back.setOnClickListener(new View.OnClickListener() {
                 @Override
                 public void onClick(View view) {
                     startService(new Intent(MainActivity.this, MyService.class));
                     finish();
                 }
             });
         } else { //Permission is not available
             Toast.makeText(this,
                     "Draw over other app permission not available. Closing the application",
                     Toast.LENGTH_SHORT).show();

             finish();
         }
     } else {
         super.onActivityResult(requestCode, resultCode, data);
     }
 }
