Call this method to ask for permission before showing chat head:

 public void addOverlay() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (!Settings.canDrawOverlays(this)) {
            askedForOverlayPermission = true;
            Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION, Uri.parse("package:" + getPackageName()));
            startActivityForResult(intent, OVERLAY_PERMISSION_CODE);
        }
    }
}

after that on Permission result if user allows for permission then only you can show chat head like below:

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == OVERLAY_PERMISSION_CODE) {
        askedForOverlayPermission = false;
        if (Settings.canDrawOverlays(this)) {
            // SYSTEM_ALERT_WINDOW permission not granted...
            //Toast.makeText(MyProtector.getContext(), "ACTION_MANAGE_OVERLAY_PERMISSION Permission Granted", Toast.LENGTH_SHORT).show();
            Intent serviceIntent = new Intent(Homepage.this, ChatHeadService.class);
            serviceIntent.putExtra("removeUserId", friendId);
            startService(serviceIntent);

        } else {
             Toast.makeText(MyProtector.getContext(), "ACTION_MANAGE_OVERLAY_PERMISSION Permission Denied", Toast.LENGTH_SHORT).show();
        }
    }
