Flutter：如何检测该应用在LD播放器上运行

Question

我正在一个具有某些安全要求的幻影应用程序中工作，其中之一是防止该应用程序在模拟器中工作，只是真实的设备，以防止模拟器中的屏幕截图和屏幕录制。

我已经使用 safe_device 和 device_info_plus 软件包要检测到该应用程序是在模拟器还是物理设备上运行的，并且每件事都可以正常工作，但是当我尝试ld player仿真器时，packages not packages no the packages no the packages not它是模拟器，因为它非常擅长嘲笑真实的设备。

因此，是否有任何想法可以检测到该设备在ld player上运行？

这是device_info_plus的输出，可能有帮助：

Answer 1

解决方案是检查这些文件夹的存在，如果存在的任何一个文件夹，则是ld player。

'/storage/emulated/0/storage/secure',
'/storage/emulated/0/Android/data/com.android.ld.appstore'

我已经实现了一种方法来列出文件夹路径列表并在存在的任何一个情况下返回true，这是以下方法：

bool anyFolderExists(List<String> foldersPaths) {
   for (String folderPath in foldersPaths) {
     if (Directory(folderPath).existsSync()) {
       return true;
     }
   }
   return false;
}

我是这样使用的：

List<String> harmfulFoldersPaths = [
  '/storage/emulated/0/storage/secure',
  '/storage/emulated/0/Android/data/com.android.ld.appstore',
];

if(anyFolderExists(harmfulFoldersPaths))
{
    print('LD Player Detected!');
}

我还使用了 device_info_plus pongage pongage决定该应用程序在模拟器上工作，因为它们似乎很通用：

"host": "ubuntu",
"device": "aosp",

我像以下以下内容一样使用它们：

final androidInfo = await deviceInfoPlugin.androidInfo;

if (androidInfo.host == 'ubuntu' && androidInfo.device == 'aosp') {
    print('LD Player Detected!');
}

但是说实话，我害怕这种方法，因为我不想误导任何用户，所以我使用 firebase远程配置在任何时候启用/禁用它，但直到现在，我才启用它们，没有记录任何问题。

检查此软件包
https://pub.dev/packages/safe_device

bool isRealDevice = await SafeDevice.isRealDevice;

如果运行设备是模拟器，此方法会返回该方法
