[英]What is the path for MIT App Inventor to access a USB drive files connected via OTG?
I have a thumb drive with videos on it and it is connected to my Android using a USB OTG cable. 我有一个带有视频的拇指驱动器,它使用USB OTG电缆连接到我的Android。 The File Manager app on my phone sees the USB storage device and I can click into it and see the folders and videos I need, but I cant figure out the correct path to load them from the USB device in app inventor.
手机上的“文件管理器”应用程序可以看到USB存储设备,我可以单击它并查看所需的文件夹和视频,但是我无法找出从app inventor中从USB设备加载它们的正确路径。
I have tried this: file:///storage/usbdisk/MyCamera/RecentClips/front.mp4
我已经尝试过:
file:///storage/usbdisk/MyCamera/RecentClips/front.mp4
when the file is in a folder on the USB drive like this: d:/MyCamera/RecentClips/front.mp4
当文件位于USB驱动器上的文件夹中时,如下所示:
d:/MyCamera/RecentClips/front.mp4
but I get an error: 但我得到一个错误:
Error 107: unable to load
错误107:无法加载
How do I access files on a USB drive in MIT App Inventor? 如何在MIT App Inventor中访问USB驱动器上的文件?
I don't know, if it is possible to access the files, but you could try the file extension and its AvailableStorageDirectories method to find out the path 我不知道是否可以访问文件,但是您可以尝试使用文件扩展名及其AvailableStorageDirectories方法来查找路径
