推荐答案

您在代码中定义了下载位置:

You defined the download location in your code:

File storagePath = new File(Environment.getExternalStorageDirectory(), "directory_name");
final File myFile = new File(storagePath,"IBM2013507.pdf");

由于要下载到 myFile ，因此可以期望在设备的外部存储目录中的"directory_name"文件夹中找到文件名为"IBM2013507.pdf"的文件.

Since you're downloading to myFile, you can expect the find the file on the device's external storage directory in the "directory_name" folder with the file name "IBM2013507.pdf".

如果您不知道它在哪里，请尝试打印 myFile 的值以查看完整路径.

If you don't know where that is, try printing the value of myFile to see the full path.
