在Android [JAVA]中看不到LocalWiFiOnlyHotspot的问题？

问题描述

我只想在android应用程序中获得一些帮助。在我的应用中，存在一个无法解决的问题，即我已编写了具有启用和禁用热点所需的所有权限的代码，当我在另一台设备上看到该热点时，该热点正在显示，但是该热点的图标不可见。我只想显示它。我正在与您分享代码的屏幕截图。

预先感谢！

 @RequiresApi(api = Build.VERSION_CODES.O)
public void turnOnHotspot() {

    try {
        if (ActivityCompat.checkSelfPermission(SendFileActivity.this,Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions,and then overriding
            //   public void onRequestPermissionsResult(int requestCode,String[] permissions,//                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
