Android 12：可以将应用程序上传到Google Play时，可以在下载中创建新文件夹

当Code Bellow作为应用程序的一部分是在本地执行（直接从Android Studio启动）时，它的工作正常。

String folderName = Environment.DIRECTORY_DOWNLOADS;
File folder = new File(Environment.getExternalStoragePublicDirectory(folderName) + "/SampleApp/");

if (!folder.mkdirs()) {
    FirebaseCrashlytics.getInstance().recordException(new Exception("Storage access class: can't create folder");
    Log.d("Debug", "Can't create new folder on path: " + folder.getPath());
    return false;
}

return folder.exists();

创建新文件夹的完整路径是：

/storage/emulated/0/Download/SampleApp

但是，当与应用程序的一部分相同的代码上传到Google Play，然后安装到同一手机时，文件夹无法创建，并且触发了异常。记录的调试路径是相同的：

/storage/emulated/0/Download/SampleApp

我仅在Android 12设备上遇到问题。特定的东西从Android 11变为12吗？我还尝试使用mkdir（），但最终结果是相同的。 Inbetweeen这两种测试都显然删除了SampleApp文件夹，因此当我尝试从Google Play尝试应用程序版本时，它不存在。

When code bellow as a part of application is executed locally (directly started from Android Studio) it works correct.

String folderName = Environment.DIRECTORY_DOWNLOADS;
File folder = new File(Environment.getExternalStoragePublicDirectory(folderName) + "/SampleApp/");

if (!folder.mkdirs()) {
    FirebaseCrashlytics.getInstance().recordException(new Exception("Storage access class: can't create folder");
    Log.d("Debug", "Can't create new folder on path: " + folder.getPath());
    return false;
}

return folder.exists();

The full path where new folder gets created is:

/storage/emulated/0/Download/SampleApp

But when the same code as a part of application gets uploaded to Google Play and then installed to the same phone, folder can't create and an exception gets triggered. Logged debug path is the same:

/storage/emulated/0/Download/SampleApp

I get the problem only on Android 12 devices. Has something specific changed from Android 11 to 12? I also tried using mkdir() but end result is the same. Inbetweeen both tests I obviously removed the SampleApp folder, so it doesn't exist when I try app version from Google Play.
